31 December 2008

Snow-Flakes

There is snow yonder cold gray sky of the morning!--and through the partially frosted window-panes, I love to watch the gradual beginning of the storm. A few feathery flakes are scattered widely through the air, and hover downward with uncertain flight, now almost alighting on the earth, now whirled again aloft into remote regions of the atmosphere. These are not the big flakes, heavy with moisture, which melt as they touch the ground, and are portentous of a soaking rain. It is to be, in good earnest, a wintry storm. The two or three people visible on the side-walks, have an aspect of endurance, a blue-nosed, frosty fortitude, which is evidently assumed in anticipation of a comfortless and blustering day. By nightfall, or at least before the sun sheds another glimmering smile upon us, the street and our little garden will be heaped with mountain snow-drifts. The soil, already frozen for weeks past, is prepared to sustain whatever burthen may be laid upon it; and, to a northern eye, the landscape will lose its melancholy bleakness and acquire a beauty of its own, when Mother Earth, like her children, shall have put on the fleecy garb of her winter's wear. The cloud-spirits are slowly weaving her white mantle. As yet, indeed, there is barely a rime like hoar frost over the brown surface of the street; the withered green of the grass-plat is still discernible; and the slated roofs of the houses do but begin to look gray, instead of black. All the snow that has yet fallen within the circumference of my view, were it heaped up together, would hardly equal the hillock of a grave. Thus gradually, by silent and stealthy influences, are great changes wrought. These little snow-particles, which the storm-spirit flings by handfulls through the air, will bury the great earth under their accumulated mass, nor permit her to behold her sister sky again for dreary months. We, likewise, shall lose sight of our mother's familiar visage, and must content ourselves with looking heavenward the oftener.

Now, leaving the storm to do his appointed office, let us sit down, pen in hand, by our fireside. Gloomy as it may seem, there is an influence productive of cheerfulness and favorable to imaginative thought, in the atmosphere of a snowy day. The native of a southern clime may woo the muse beneath the heavy shade of summer foliage, reclining on banks of turf, while the sound of singing birds and warbling rivulets chimes in with the music of his soul. In our brief summer, I do not think, but only exist in the vague enjoyment of a dream. My hour of inspiration--if that hour ever comes--is when the green log hisses upon the hearth, and the bright flame, brighter for the gloom of the chamber, rustles high up the chimney, and the coals drop tinkling down among the growing heaps of ashes. When the casement rattles in the gust, and the snow-flakes or the sleety raindrops pelt hard against the window-panes, then I spread out my sheet of paper, with the certainty that thoughts and fancies will gleam forth upon it, like stars at twilight, or like violets in May--perhaps to fade as soon. However transitory their glow, they at least shine amid the darksome shadow which the clouds of the outward sky fling through the room. Blessed, therefore, and reverently welcomed by me, her true-born son, be New-England's winter, which makes us, one and all, the nurslings of the storm, and sings a familiar lullaby even in the wildest shriek of the December blast. Now look we forth again, and see how much of his task the storm-spirit has done.

Slow and sure! He has the day, perchance the week, before him, and may take his own time to accomplish Nature's burial in snow. A smooth mantle is scarcely yet thrown over the withered grass-plat, and the dry stalks of annuals still thrust themselves through the white surface in all parts of the garden. The leafless rose bushes stand shivering in a shallow snow-drift, looking, poor things! as disconsolate as if they possessed a human consciousness of the dreary scene. This is a sad time for the shrubs that do not perish with the summer; they neither live nor die; what they retain of life seems but the chilling sense of death. Very sad are the flower-shrubs in mid-winter! The roofs of the houses are now all white, save where the eddying wind has kept them bare at the bleak corners. To discern the real intensity of the storm, we must fix upon some distant object,--as yonder spire,--and observe how the riotous gust fights with the descending snow throughout the intervening space. Sometimes the entire prospect is obscured; then, again, we have a distinct, but transient glimpse of the tall steeple, like a giant's ghost; and now the dense wreaths sweep between, as if demons were flinging snow-drifts at each other, in mid-air. Look next into the street, where we have an amusing parallel to the combat of those fancied demons in the upper regions. It is a snow-battle of school-boys. What a pretty satire on war and military glory might be written, in the form of a child's story, by describing the snow-ball fights of two rival schools, the alternate defeats and victories of each, and the final triumph of one party, or perhaps of neither! What pitched battles, worthy to be chanted in Homeric strains! What storming of fortresses, built all of massive snow-blocks! What feats of individual prowess, and embodied onsets of martial enthusiasm! And when some well contested and decisive victory had put a period to the war, both armies should unite to build a lofty monument of snow upon the battle-field, and crown it with the victor's statue, hewn of the same frozen marble. In a few days or weeks thereafter, the passer-by would observe a shapeless mound upon the level common; and, unmindful of the famous victory, would ask--"How came it there? Who reared it? And what means it?" The shattered pedestal of many a battle-monument has provoked these questions, when none could answer.

Turn we again to the fireside, and sit musing there, lending our ears to the wind, till perhaps it shall seem like an articulate voice, and dictate wild and airy matter for the pen. Would it might inspire me to sketch out the personification of a New-England winter! And that idea, if I can seize the snow-wreathed figures that flit before my fancy, shall be the theme of the next page.

How does Winter herald his approach? By the shrieking blast of latter autumn, which is Nature's cry of lamentation, as the destroyer rushes among the shivering groves where she has lingered, and scatters the sear leaves upon the tempest. When that cry is heard the people wrap themselves in cloaks, and shake their heads disconsolately, saying--"Winter is at hand!" Then the axe of the wood-cutter echoes sharp and diligently in the forest,--then the coal-merchants rejoice, because each shriek of Nature in her agony adds something to the price of coal per ton--then the peat-smoke spreads its aromatic fragrance through the atmosphere. A few days more; and at eventide, the children look out of the window, and dimly perceive the flaunting of a snowy mantle in the air. It is stern Winter's vesture. They crowd around the hearth, and cling to their mother's gown, or press between their father's knees, affrighted by the hollow roaring voice, that bellows adown the wide flue of the chimney. It is the voice of Winter; and when parents and children hear it, they shudder and exclaim--"Winter is come! Cold Winter has begun his reign already!" Now, throughout New-England, each hearth becomes an altar, sending up the smoke of a continued sacrifice to the immitigable deity who tyrannizes over forest, country-side, and town. Wrapt in his white mantle, his staff a huge icicle, his beard and hair a windtossed snow-drift, he travels over the land, in the midst of the northern blast; and wo to the homeless wanderer whom he finds upon his path! There he lies stark and stiff, a human shape of ice, on the spot where Winter overtook him. On strides the tyrant over the rushing rivers and broad lakes, which turn to rock beneath his footsteps. His dreary empire is established; all around stretches the desolation of the Pole. Yet not ungrateful be his New-England children--(for Winter is our sire, though a stem and rough one)--not ungrateful even for the severities, which have nourished our unyielding strength of character. And let us thank him, too, for the sleigh-rides, cheered by the music of merry bells--for the crackling and rustling hearth, when the ruddy fire-light gleams on hardy Manhood and the blooming cheek of Woman--for all the home-enjoyments, and the kindred virtues, which flourish in a frozen soil. Not that we grieve, when, after some seven months of storm and bitter frost, Spring, in the guise of a flower-crowned virgin, is seen driving away the hoary despot, pelting him with violets by the handful, and strewing green grass on the path behind him. Often, ere he will give up his empire, old Winter rushes fiercely back, and hurls a snow-drift at the shrinking form of Spring; yet, step by step, he is compelled to retreat northward and spends the summer months within the Arctic circle.

Such fantasies, intermixed among graver toils of mind, have made the winter's day pass pleasantly. Meanwhile, the storm has raged without abatement, and now, as the brief afternoon declines, is tossing denser volumes to and fro about the atmosphere. On the window-sill, there is a layer of snow, reaching half way up the lowest pane of glass. The garden is one unbroken bed. Along the street are two or three spots of uncovered earth, where the gust has whirled away the snow, heaping it elsewhere to the fence-tops, or piling huge banks against the doors of houses. A solitary passenger is seen, now striding mid-leg deep across a drift, now scudding over the bare ground, while his cloak is swollen with the wind. And now the gingling of bells, a sluggish sound; responsive to the horse's toilsome progress through the unbroken drifts, announces the passage of a sleigh, with a boy clinging behind, and ducking his head to escape detection by the driver. Next comes a sledge, laden with wood for some unthrifty housekeeper, whom winter has surprised at a cold hearth. But what dismal equipage now struggles along the uneven street? A sable hearse, bestrewn with snow, is bearing a dead man through the storm to his frozen bed. Oh, how dreary is a burial in winter, when the bosom of Mother Earth has no warmth for her poor child!

Evening--the early eve of December--begins to spread its deepening veil over the comfortless scene; the fire-light gradually brightens, and throws my flickering shadow upon the walls and ceiling of the chamber; but still the storm rages and rattles against the windows. Alas! I shiver, and think it time to be disconsolate. But, taking a farewell glance at dead Nature in her shroud, I perceive a flock of snow-birds, skimming lightsomely through the tempest, and flitting from drift to drift, as sportively as swallows in the delightful prime of summer. Whence come they? Where do they build their nests, and seek their food? Why, having airy wings, do they not follow summer around the earth, instead of making themselves the playmates of the storm, and fluttering on the dreary verge of the winter's eve? I know not whence they come, nor why; yet my spirit has been cheered by that wandering flock of snow-birds.

16 November 2008

I was watching NASA TV when the Shuttle performed its Terminal Initiation burn took place. They had been showing images of the Shuttle and the Moon taken from an external camera on the ISS. The Shuttle just looked like a pulsing light and there wasn't much detail in the Moon. They said they were about 20 seconds from the burn so I started a countdown and right on schedule there was a flash of light from the Shuttle. It didn't last lone and I don't know if I saw the whole burn or if the auto exposure on the camera stopped the lens down so I didn't see the whole burn. It was still mildly interesting to have seen it in real time.

There have been some problems with the Shuttle that NASA is watching. There was a piece of heat shield blanket that was lost. It was 4" wide by 1-1.5' long. NASA says it came from an area of the shuttle that is "not of great concern" [emphasis mine]. They have had blanket problems before and gone outside to remove a piece of protruding blanket and I think filled in a gap left by missing blanket on another occasion. I haven't seen anything saying if they are considering a repair this time around. They are also having trouble with the KU band microwave antenna. That antenna is used to send TV back to earth and also as a radar antenna for rendezvous and docking. The antenna was successfully used rot rendezvous but they are still experiencing problems using it for TV. Other than that the mission is going perfectly.

14 November 2008

I got online in time to see the Airstream driving the astronauts out to the Pad and stayed with the stream until after MECO.

The decision to launch seemed risky to me. They found that the closeout team had failed to secure the frame that seals the end of the white room against the shuttle and it was flapping around in the breeze. With 16 minutes remaining in the final hold they were asking if there was enough time to get someone back up there to secure the frame. They didn't seem to think that there would be a problem with it impacting the Shuttle since there is a railing that it would bang into first. I wonder if it might bang into the railing with enough force to tear something free or break something that would then become a projectile that could impact shuttle tiles as it fell. They seemed to feel that the risk was acceptable and launched without trying to secure the frame. There were no immediate reports of adverse affects immediately after launch.

There are not many stars visible tonight. I lost Jupiters moons while observing them. There is boiling across the face of the Moon. I had to do a lot of refocusing. Earlier in the day there were some stripes of clouds visible and I wonder if they are still around but not illuminated enough for me to see them.

The most striking features are in the area of Schicard.

  • there is an area of flat terrain to the east of Schicard that appears to surround the crater and looks to be circular as though it is a walled plain or drowned crater.
  • I get the same impression from an area southwest of Schiller which extends south to include Segner.
  • There is a nice indication of relief inside the north rim of Schiller – is it an indication that libration is to the north.
    [the Moon is actually tipped up somewhat]

There are lots of chalky white spots between Sinus Medii and Mare Nectaris.

I don’t see any libration features on the eastern limb.

3 November 2008

I decided to look more at the length of sunlight, and eariest and latest sunrise and sunset relative to the solstices and start and end of daylight saving time.

I started with the event that is going on right now. It charted out pretty cleanly.

Then I went back and worked on the Summer Solstice events. First I found that I had to input data for one more month to cover the switch from Standard Time to Daylight Saving Time and the longest day of the year. When I got all of the data inputted and applied some conditional formatting to the spreadsheet to identify the date(s) of earliest sunrise, latest sunset and longest daylight I found that there was a lot of overlap between them.

Eariest Sunrise12-16Jun08
Longest Day15-16Jun08
18-25Jun08
Latest Sunset22Jun08-3Jul08
This made it harder to color code the chart to identify the days. And yes, there is a short day in that run of longest days.

2 November 2008

We just switched from Daylight Saving Time to Standard Time. The Sun had been waking up about a minute earlier each day and going to bed about a minute earlier. Because of the time change the Sun will wake up almost an hour earlier today (0627 EST) than it did yesterday (0726 EDT). The Sun won't wake up as late as it did yesterday again until after we have returned to Daylight Saving Time again in April. On the days during the winter when the Sun wakes up the latest (30Dec08-9Jan09) it only wakes up at 0720.

A piece of garbage thrown overboard from the ISS back in Jul07 is about to reenter earth's atmosphere. The Early Amonia Servicer is the size of a double-wide refrigerator and ways 1400 pounds.


detail from a NASA graphic

It is expected to be completely incinerated as it passes through Earth's atmosphere and pose no threat to earth. The trajectory places reentry in the "early hours" (0346 UTC) of 3Nov08, ±15 hours. Given the high degree of uncertainty about the time of reentry it is impossible to say where it will take place, on which orbit, or even if it will be during the "early hours" of the 3rd. But if it reenters at 0346 UTC the EAS Ground Tacks, at The Center for Orbital and Reentry Debris Studies, shows that it will occur over the Pacific Ocean SW of Baja, Mexico, while on an ascending pass. That would place reentry at ~1946 PST tonight or about 30 minutes after the end of Astronomical Twilight.

Space Weather has a Satellite Tracker application, but it does not show any visible passes of the EAS over the Bronx.

I checked out the STS-126 mission timeline and, given good weather, we should have a chance of seeing it at MECO as it passes NYC but the subsequent ISS passes prior to docking are both short and lot altitude so it is doubtful that we will have a chance of seeing the two craft flying in tandem.

It seems like all of a sudden all of the trees in my neighborhood are at near peak fall coloring. It wasn't like this when I went out this morning.

?could it be the return of milder weather after the recent rainfall
or was it just their time to turn color

NASA has moved the launch date for STS-126 again. The new date is

CNN article

The HST Repair Mission can't fly before Apr09 (CNN) or May09 (BBC) because that is the earliest the repair part that is needed to resolve the recent problems will be ready. In the meantime HST is gathering and sending images back to earth. NASA feels that they will be able to fly the HST Servicing Mission at any time without having an adverse impact on future Shuttle missions to the ISS and ISS construction completion.

Sunspots Observed

There have been some spots this month but they are mainly smaller spots than I can see with my small binocular. I saw spots on only two days this month.

29 October 2008

I went out at 1100 EDT today to make a sun observation and had trouble making it to the end of the block due to the headwind. It has been gusty most of the afternoon and I am extending my charting of the weather another day. While I was out I got caught in a brief hail storm. Obviously I didn't need the welders glass since there was no visible sun although it was bright enough that there were shadows close to the bases of objects.

28 October 2008

The surf is already up in the toilet bowl. They are predicting higher wind gust tonight than we had last Saturday. I am going to graph them again. The rain is knocking the leaves out of the trees and there is supposed to be some flooding as a result of clogged storm drains. And in the Pocono Mountains they are supposed to get a couple inches of snow.

27 October 2008

It got extremely windy around here Saturday evening. When I went home it was just starting and I occasionally had trouble walking across the wind. There is a tree that must be nearly 100 feet tall in an inside corner of my building and as I was laying in bread reading I could see the whole tree whipping around. I decided to compare the conditions at the nearby airports.

The Wild Swans at Coole

The trees are in their autumn beauty,
The woodland paths are dry,
Under the October twilight the water
Mirrors a still sky;
Upon the brimming water among the stones
Are nine-and-fifty swans.

The nineteenth autumn has come upon me
Since I first made my count;
I saw, before I had well finished,
All suddenly mount
And scatter wheeling in great broken rings
Under their clamorous wings.

I have looked upon those brilliant creatures'
And now my heart is sore.
All's changed since I, hearing at twilight,
The first time on this shore,
The bell-beat of their wings above my head,
Trod with a lighter tread.

Unwearied still, lover by lover,
They paddle in the cold
Companionable streams or climb the air;
Their hearts have not grown old;
Passion or conquest, wander where they will,
Attend upon yhem still.

But now they drift on the still water,
Mysterious, beautiful;
Among what rushes will they build,
By what lake's edge or pool
Delight men's eyes when I awake some day
To find they have flown away?

William B. Yeats




I was wondering how much of a stabilizing effect proximity to large bodies of water plays on temperature variation so I charted the temperature for my normal Central Park weather station and also LaGuardia Airport which is spitting distance from home and is right on Long Island Sound, JFK Airport which is on Jamaica Bay and right off of the Atlantic Ocean, Newark Airport which is near NY Harbor, and Westchester County Airport in Westchester County which is probably the farthest station from water. I also looked at Relative Humidity

The frost and freeze warnings are moving closer to the City. I decided to take a romp through the NOAA Glossary to find out exactly what these things mean.

Frost Advisory
Issued during the growing season when widespread frost formation is expected over an extensive area. Surface temperatures are usually in the mid 30s Fahrenheit.

Freeze Warning
Issued during the growing season when surface temperatures are expected to drop below freezing over a large area for an extended period of time, regardless whether or not frost develops.

Other terms used in the forecasts, which are not in the glossary, are "killing frost" and "hard freeze."

And since there is rain on the way I took another look at precipitation.

Fog
(abbrev. F) Fog is water droplets suspended in the air at the Earth's surface. Fog is often hazardous when the visibility is reduced to ¼ mile or less.

Mist
A visible aggregate of minute water particles suspended in the atmosphere that reduces visibility to less than 7 statute miles, but greater than or equal to 5/8 statute miles. It does not reduce visibility as much as fog and is often confused with drizzle.

Drizzle
Precipitation consisting of numerous minute droplets of water less than 0.5 mm (500 micrometers) in diameter.

Scattered Showers
When used to describe precipitation (for example: "scattered showers") - Area coverage of convective weather affecting 30 percent to 50 percent of a forecast zone (s). When used to describe sky cover: 3/8th to 4/8th (sky cover is measured in eighths or oktas) of the sky covered by clouds. In U.S. weather observing procedures, this is reported with the contraction "SCT."

Showers
A descriptor, SH, used to qualify precipitation characterized by the suddenness with which they start and stop, by the rapid changes of intensity, and usually by rapid changes in the appearance of the sky.

Rain
Precipitation that falls to earth in drops more than 0.5 mm in diameter.

Thunderstorms
A local storm produced by a cumulonimbus cloud and accompanied by lightning and thunder.

Frost
(Abbrev. FRST) - Frost describes the formation of thin ice crystals on the ground or other surfaces in the form of scales, needles, feathers, or fans. Frost develops under conditions similar to dew, except the temperatures of the Earth's surface and earthbound objects falls below 32°F. As with the term "freeze," this condition is primarily significant during the growing season. If a frost period is sufficiently severe to end the growing season or delay its beginning, it is commonly referred to as a "killing frost." Because frost is primarily an event that occurs as the result of radiational cooling, it frequently occurs with a thermometer level temperature in the mid-30s.

Flurries
Snow flurries are an intermittent light snowfall of short duration (generally light snow showers) with no measurable accumulation (trace category).

Snow
Precipitation in the form of ice crystals, mainly of intricately branched, hexagonal form and often agglomerated into snowflakes, formed directly from the freezing [deposition] of the water vapor in the air.

Sleet
(PL) - Sleet is defined as pellets of ice composed of frozen or mostly frozen raindrops or refrozen partially melted snowflakes. These pellets of ice usually bounce after hitting the ground or other hard surfaces. Heavy sleet is a relatively rare event defined as an accumulation of ice pellets covering the ground to a depth of 1/2" or more.

Hail
Showery precipitation in the form of irregular pellets or balls of ice more than 5 mm in diameter, falling from a cumulonimbus cloud.

Freezing Fog
A suspension of numerous minute ice crystals in the air, or water droplets at temperatures below 0ยบ Celsius, based at the Earth's surface, which reduces horizontal visibility; also called ice fog.

Freezing Rain
Rain that falls as a liquid but freezes into glaze upon contact with the ground.

There are some qualifiers that are used with the precipitation descriptions that I also ferreted out.

Possible
not defined

Chance
A National Weather Service precipitation descriptor for 30, 40, or 50 percent chance of measurable precipitation (0.01 inch). When the precipitation is convective in nature, the term scattered is used. See Precipitation Probability (PoP).

Slight Chance
In probability of precipitation statements, usually equivalent to a 20 percent chance.

Slight Risk
(of severe thunderstorms)- Severe thunderstorms are expected to affect between 2 and 5 percent of the area. A slight risk generally implies that severe weather events are expected to be isolated.

Likely
(abbrev. LKLY) In probability of precipitation statements, the equivalent of a 60 or 70 percent chance.

Occasional
not defined
