Weather Pack For September 6 2012
2012-09-06 08:00:38

Today on Weather Pack we are going to examine the surface wind around a mature low pressure system, which means that the low pressure has an occluded front associated with it. Yellow Star: The forecasted surface winds would be out of the Northwest as the flow behind the low is counter-clockwise. Green Star: Anyone that is forecasting for the green star would be looking at the winds coming...

Types Of Air
2012-07-19 13:21:39

There are many types of air present in our atmosphere. The first type is known as dry air. Dry air is described as having less than 1% of moisture in it. The best location to find this type of air is in the Southwest part of the United States and also in the Middle East. The second type of air is called moist air. This air is best defined as having moisture present in it. Anything greater...

Difference Between Onshore And Offshore Flow
2012-07-16 11:34:51

Onshore flow describes the movement of any weather feature moving towards the shore. The most common weather features that are affiliated with onshore flow are Hurricanes and the daily sea breeze. What happens with a hurricane is the Northeast side of the storm will produce winds out of the Southeast to South which will force the ocean water (Storm Surge) towards the coast along with all the...

Topographic Features Impact On The Weather
2012-07-10 20:45:32

The first topographic feature that I would like to talk about today is the Rocky Mountains. The Rocky mountains with their rugged terrain and high elevation can really become a large impact on weather patterns in the United States. First, the Rockies provide the Central Plains with the cold air aloft that is needed in the formation of severe weather to include tornadoes. Secondly, the...

Polar Front Jet on the Water Vapor Image
2012-07-10 17:35:31

Water vapor satellite is used to identify moisture in the atmosphere. We can also use it to help us identify the Polar front Jetstream. The Jetstream is outlined in the above image with a red line. As you can see it travels through an area of black or what we refer to as dry air. The reason the polar front jet travels through dry air is that the winds associated with this jet can exceed...

Continental Tropical Air Mass
2012-07-05 10:54:23

Another type of air mass that we are going to talk about is called Continental Tropical also known as CT. This type of air mass can be best described as having dry and hot conditions. The reason for this is because it forms over the land and also is found in the hot tropical regions. The best place in the United States to find this type of air mass is the Southwest portion of the United States....

A Cold Front On The Weather Map
2012-06-18 21:09:52

Looking at our weather map above we can see a cold front moving through the states of Oklahoma and Kansas. The major thing about a cold front is the weather it can bring with it. The eastern side of the cold front provides two chances to receive precipitation. The first one is known as a squall line which usually forms some 50-150 miles ahead of the cold front. The squall line can be...

A Warm Front On The Weather Map
2012-06-18 16:42:53

If you look at our weather map above you see a warm front extending from Iowa into the Great Lakes region. What a warm front does is separate warm air from cool air. On the north side of the front the temps will be about 15-20 degrees cooler than on the south side of the front. The warm front is depicted on a weather map as having red half circles. The reason for using half circles it...

Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
