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

Good read, thanks for the info. I think i will write a book on the years Tennessee had no winters. This should be a pretty thick book. Thanks Again have a good weekend coming up.... 

Also on Sept. 26,2013 Sun comes up at 7:32 A.M. and set at 7:32 P.M. Here in Chattanooga. So about as close as you can come too same day light & darkens . Really a full 24 hours is a little more than 24. But this again happens in the Spring time also with the same amount of day vs dark. Does not happen in Summer or Winter.

Calendar for September 18th, 2013
Ember Days

The Almanac traditionally marks the four periods formerly observed by the Roman Catholic and Anglican churches for prayer, fasting, and the ordination of clergy. These Ember Days are the Wednesdays, Fridays, and Saturdays that follow in succession after (1) the First Sunday in Lent; (2) Whitsunday/Pentecost; (3) the Feast of the Holy Cross, September 14; and (4) the Feast of St. Lucia, December 13. The word ember is perhaps a corruption of the Latin quatuor tempora, "four times." Folklore has it that the weather on each of the three days foretells the weather for three successive months; for example, in the case of September's Ember Days: Wednesday, September 18, forecasts the weather for October; Friday, September 20, for November; and Saturday, September 21, for December.

Antarctic summers average just above freezing, with the more mountainous East Antarctica colder than its western counterpart. The lowest temperature in the world, -89.6 degrees Celsius (-129.3 degrees Fahrenheit), was recorded at the Russian Vostok station in Antarctica. 

Do you know the difference between drizzle vs light rain.? Well here one difference. We all seen when it is raining the the puddles it makes and how light rain breaks the surface and makes a wave in the water. But very fine drizzle will not make a wave on the waters surface. This is the difference in drizzle and light rain. Anytime rain breaks the surface of the water, it not drizzle anymore.

 Lowest Temperatures
The lowest temperature ever recorded in the United States was -80 degrees Fahrenheit (-62 degrees Celsius) on January 23, 1971 at Prospect Creek Camp, located near the Arctic Circle along the Alaska pipeline. This is not much warmer than the -81.4 °F record low for North America that Snag in the Yukon dropped to on February 3, 1947. On that extremely cold February day, Tanacross Alaska reached -75 °F.
The lower 48 states of the US hit their official coldest temperature of -70 °F on January 20, 1954 at Rogers Pass, Montana. The pass sits at 5,470 feet (1,667 metres) elevation in the Rocky Mountains, northwest of Helena.

Questions and Answers About Winter

Question: Why is there such a time lag between the shortest day of the year and the lowest average daily temperature of the year?

Answer:This is the shortest day of the year—the time when the Sun reaches its southernmost point in the sky. Although this part of Earth is cooling, its great thermal mass still retains some heat from the summer and fall. As the gradual cooling process continues over the next two months, temperatures will continue to fall, and the coldest temperatures will be recorded. The same pattern holds true for the summer solstice in June, as the year's highest temperatures are recorded later, in July and August.

Question: Was Stonehenge built to celebrate the winter solstice?

Answer: That's one theory. Stonehenge was constructed in several phases over a period of many centuries. Due to the alignment of the stones, experts acknowledge that the design appears to correspond with the use of the solstices and possibly other solar and lunar astronomical events in some fashion. There are several theories as to why the structure was built, including that the area was used as a temple to worship the Sun; as a royal burial ground; and/or as a type of astronomical observatory. However, because none of these theories has been proven correct as yet, the true reason (or reasons) for Stonehenge remains a mystery.

This part is about setting up Anemometers... Installing A Wind Speed Sensor

The goal of installing a wind speed meter (anemometer) is to position it in a location where the wind flows freely and is not influenced by nearby objects. The World Meteorological Organization has set the international standard height for wind measurement devices at 10 meters (33 feet) above ground, with no obstructions at or above this level. Attaining this height can not only be difficult but expensive as well. For most home weather stations installations, striking a compromise is likely the best alternative.

So what are your alternatives? Part of the answer to that is how accurate you want your measurements to be? Wind observations taken at 7 meters (23 feet) are accurate enough for the National Weather Service to accept. For a rooftop installation, the minimum height to avoid anomalous winds caused by the roof itself is 3 meters (10 feet) above the most exposed part. Accuracy of the wind speed indicator is not just a matter of height. Local obstructions like nearby mature trees, houses and buildings all have the potential of impacting anemometer readings. Unfortunately this is the reality of taking wind measurements and the choice of how to deal with it is ultimately yours.

Everyone i guess has heard how warm it is at the winter Olympics. Here a article about it. If you are like me you don't watch it.https://patriotpost.us/opinion/23393

Sheesh. Anything those AGW types can use to push their agenda. Anyone else notice there are palm trees outside that big ice arena?

Weather term :::
Rope Stage
The dissipating stage of a tornado, characterized by thinning and shrinking of the condensation funnel into a rope (or rope funnel). Damage still is possible during this stage.

Weird Weather Facts:
On 14th April, 1986 Bangladesh was hit by the biggest hail stones ever recorded - weighing in at over 1kg each - killing 92 people. 1KG is about 2.2 pounds or 35.3 ounces. Not sure if this record has been broken, This is the latest i have on it without a lot of research. Maybe someone knows of some bigger hail stones.

Difference between climate and weather.... We hear about weather and climate all of the time. Most of us check the local weather forecast to plan our days. And climate change is certainly a “hot” topic in the news. There is, however, still a lot of confusion over the difference between the two.

Think about it this way: Climate is what you expect, weather is what you get.

Weather is what you see outside on any particular day. So, for example, it may be 75° degrees and sunny or it could be 20° degrees with heavy snow. That’s the weather.

Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. This is climate. The climate record also includes extreme values such as record high temperatures or record amounts of rainfall. If you’ve ever heard your local weather person say “today we hit a record high for this day,” she is talking about climate records.

So when we are talking about climate change, we are talking about changes in long-term averages of daily weather. In most places, weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, however, is the average of weather over time and space.

A bolt of lightning can travel at up to 136,000mph and reach temperatures of 30,000 °Celsius — hotter than the surface of the Sun!

We think zero is pretty cold, and it is very cold. But here is cold. Absolute zero is believed to be the lowest possible temperature, the point at which all molecular motion would cease. - 459.6 F...
