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 from the South-Southeast just right ahead of the warm front of the low pressure system. Red...

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 than 1% would be described as being moist. The best places to find this type of air is along the...

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 extensive precipitation shields. Another feature is known as the Sea breeze. The sea breeze happens...

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 Rocky mountains act as a barrier for any large weather system that moves onshore along the Pacific...

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 150mph which keeps the air moving too fast to develop moisture at high levels. The polar front jet...
