Some things you may or may not know about the Weather.

Post by windstorm on 2013-07-31, 7:48 am

I hope over time i can add some things in here about the weather that you may or may not know about the weather. It may be a slow go for a while. But if anyone wants to add to this jump right in. Here one. ::::: What is the real shape of a raindrop?

Based on pictures we've seen in magazines, on TV, and elsewhere, most of us would guess that raindrops are shaped like a teardrop. It turns out that this is not the real shape of a raindrop. Small raindrops (< 1mm in diameter) are spherical, like a round ball. This is because a sphere is the shape that requires the least amount of energy for the drop to hold itself together.

As drops grow bigger than a millimeter or so, they start to become flat along their bottom edge as they fall, due to the resistance of air flowing around the drop. By the time a drop reaches 2-3 mm in diameter, it looks more like a hamburger bun than a sphere. Drops bigger than about 6 mm in diameter are relatively rare because the air resistance tends to cause the drops to breakup as they fall. popcorn

I guess we all know this but here it is. Does Wetter Snow Flakes mean colder air ? No. It means, Wetter snowflakes mean the temperature is rising, while dry snowflakes indicate colder air.Very Happy

yes.But you can also get big snows with colder temps. But really super cold air does cut down on the amounts of snow. Because cold air hold less water. When the upper air is say around freezing  lot of times u see these big snow flakes. So a degree or two could change it back to rain even if ground temp is below freezing in which you would have frz rain as it hit the surface. Some parts in the North and South Pole only get maybe 2 to 4 inches of snow a year because of the really super cold dry air. Dry
snow has more air in it also.

normally and alot of times, we get the extreme cold behind a big winter storm... winter of eighty five was a prime example... each big snow we got that year was followed by extreme cold. miinus 10 year was the coldest temp here in jackson that winter, thats ambient temp too

Back in 65 or 66 in January we had a 8 or 9 inch snow in Chattanooga. Snow started about 1 A.M. early Saturday morning. I think when i work up around 6:30 temp was 29 and snowing. The temp was to go down all day long. By 4:30 that afternoon the snow had stop with clear sky's and a temp of 10 degrees. Next morning it was minus 10. I had to get out in it because I had a paper route back in the day. I love it. Water pipes stayed frozen for 7 days. Did not get above freezing for a week. During that time we had a few days later freezing rain with a temp of 21. It has been minus 10 in Chattanooga two or 3 times. I would have to ck to see for sure how many times. Not seen a system like that since, with the snow first and then a extreme cold.  I have seen some extreme cold but not many systems like that one.

When was the Jet Stream discover ??::::: A jet stream is a flat and narrow tube of air that moves more rapidly than the surrounding air. Discovered by World War II bomber pilots flying over Japan and the Mediterranean Sea, jet streams have become important with the advent of airplanes capable of cruising at over 30,000 feet (9,144 meters). The currents of air flow from west to east and are usually a few miles deep, up to 100 miles (160 kilometers) wide, and well over 1,000 miles (1,600 kilometers) in length. The air current must flow at over 57.5 miles (92 kilometers) per hour.

There are two polar jet streams, one in each hemisphere. They meander between 30 and 70 degrees latitude, occur at altitudes of 25,000 to 35,000 feet (7,620 to 10,668 meters), and achieve maximum speeds of over 230 miles (368 kilometers) per hour. The subtropical jet streams (again one per hemisphere) wander between 20 and 50 degrees latitude. They are found at altitudes of 30,000 to 45,000 feet (9,144 to 13,715 meters) and have speeds of over 345 miles (552 kilometers) per hour.

P.S. This is what i have always read. Seen one person say it was discover in japan with an air balloon in the 1920's. This  is highly unlikely. I go with the first read. How do u discover the jet stream back in the 1920's with that. ???popcorn

Yep Bruce, it sure has, I can't think of a morning it hasn't been foggy to some degree. In fact, Friday was not only foggy in the morning, but also that evening right after sunset. That must surely equal a monster snowstorm,, right, lol. 2 snows in the same day haha

Ah, the year w/o a summer. My favorite year! Kind of like this year. Although 1816 was even way colder than this year, and affected New England more than TN. I wish there were more records being kept in this part of the country back then, as I'm sure there were probably some affects here, esp. in the mtns.

Most lightning deaths in the United States occur while people are enjoying outdoor activities, with fishing the most deadly, government weather officials say.

From 2006 to 2012, 238 people died after being struck by lightning in the country — 82 percent of them male. Of the total number of victims, 152 were taking part in leisure activities, according to new findings from the National Weather Service .

Fishing topped the list with 26 lightning deaths, followed by camping with 15 deaths, boating with 14, soccer with 12 and golf with eight, NWS officials said. Other lightning victims died while at the beach, swimming, walking, running or picnicking. [Electric Earth: Stunning Images of Lightning]

Activities like fishing and camping may be most hazardous during a storm because they often require extra time to take shelter in a safe place, explained John Jensenius, a lightning safety specialist with the NWS.

"People often wait far too long to head to safety when a storm is approaching, and that puts them in a dangerous and potentially deadly situation," Jensenius said in a statement.

So far this year, seven people have been killed by lighting — three of them men who were fishing, according to NWS data.

The findings were announced as the NWS kicks off its National Lightning Safety Awareness Week just in time for summer — peak thunderstorm season.

Lightning deaths in the country have been on a decades-long decline, which experts often attribute to better education about lightning safety. Since 2001 — the year the NWS campaign launched — there have been 37 lightning deaths in the United States annually, down from an average of 73 in the years before the campaign began. (Compare that further to the 1940s, when lightning deaths averaged above 300.)

Jensenius said the NWS campaign has been especially effective in the golf community. "We believe our outreach has made a huge difference since lightning-related deaths on golf courses have decreased by 75 percent," he said in a statement.

The NWS says the best way to avoid injury or death by lightning is to monitor the weather and cancel or postpone outdoor activities when a thunderstorm is rolling in. Lightning can strike from 10 miles (16 kilometers) away and the best place to take shelter is a building with four walls and a roof, or a car — in other words, a hut, cabana or tent will not save you from a flash of lightning, the NWS says.

I found an interesting article about the year without a summer in NE TN, specifically Kingsport, TN. I don't know who this Vince Staten is, or how reputable his sources are, but this is the first time I've ever seen anything written about 1816 for TN at all.  Here is the blog article:

The Year Without a Summer, The Year the Holston River Froze - 1816




Barney Pendleton says that with all the cold weather I need to write a column about 1816, the Year Without a Summer, the Year the Holston River Froze. Then I remembered I had already written that column, five years ago!

This column was originally published January 16, 2005:


Torrential rains in sunny Southern California?

A deadly tsunami in the South Pacific?

Reports of mudslides and volcanoes have been all over the news as the weather has moved from its little front-page box to take over the headlines.

In short, the weather has been crazy.

But nothing like 1816.

That was the Year of Hard Times, the Year Without a Summer. That was the year that ponds in the Kingsport area - it wasn’t called Kingsport yet - iced over in July.

Those who survived that crazy climate change would later refer to it as “Eighteen hundred and froze to death.”

It all began in 1812 when the Tambora island volcano in Indonesia awoke from a 5,000-year slumber and began emitting steam and ash. Then on April 5, 1815 Tambora exploded with such force that its volcanic column soared 15 miles into the sky. The blast was heard 600 miles away. But it was only the beginning.

Five days later Tambora really blew her stack, sending volcanic matter up 25 miles.

The superheated flows of ash, rock and pumice from the mountain wiped out the province’s entire population of ten thousand people. And the resulting 20-foot tsunamis swamped nearby islands. In the end the death toll reached more than 117,000.

The Tambora eruption has been assigned retrospectively a 7 on the 8-point VEI (Volcanic Explosivity Index), the only 7 since Baitoushan on the China-Korea border erupted in 1050 A.D. It was a whopper.

It would be a year before the effects of Tambora would be felt around here but felt they were.

As the late Muriel Spoden details in her book “The Netherland Inn Chronicles,” “All went exceedingly well for (merchant) George Hale until April of 1816 when all of the citizens in the Christianville Boat Yard area experienced the beginning of a very hard time.”

It was a very hard time, particularly in the Northeastern states. Adino Brackett of Lancaster, New Hampshire would later record in his diary 1816, “This past summer and fall (of 1816) have been so cold and miserable that I have from despair kept no account of the weather. It could have been nothing but a repeatation of frost and drought.”

Even Europe was affected. “A wet, ungenial summer” ruined a Swiss holiday for Mary Shelley, John Polidori and their friends but produced a happy outcome for readers. Forced to stay indoors Shelley wrote “Frankenstein” and Polidori penned “The Vampyre.”

The odd weather patterns resulting from sunlight being blocked by all that volcanic ash was felt as far south as northeast Tennessee. Locals noted an unusual red glow in sunsets.

Spoden writes, “Starting in April, (1816) severe cold weather, with snow, ice and frost became progressively worse through August…. People froze to death as snow and sleet fell for seventeen days in May. August was worse as ice coating killed everything green and ice covered ponds and rivers.”

There was even a frost on August 22. Spoden says, “Crops were ruined. Seed corn stored in 1815 sold in the spring of 1817 for $5 to $10 a bushel. To add to the farming and boating woes, the spring flood curtailed business throughout the area. These and other problems caused George Hale to lose the King Saltworks contracts, and many charge customers were unable to pay their bills.”

It was a very hard time indeed in east Tennessee

But the long-term effects of the Year without a Summer were even more profound for the country. Dave Thurlow of the Weather Notebook radio show says the impact is still being felt today, particularly the effect of one June cold snap that killed the vegetable crop across the Northeast and inspired many bankrupt farmers to pack up and move to the more temperate Midwest. “Had there been no reason for European settlers to head west at that time, the nation's distribution of farmland and manufacturing, and its balance of power, might have turned out much differently. You could say that our lives today are, in some ways, the product of a 5-day cold snap (189) years ago.”
