Ocean Currents Responsible For Wetter Northern Hemisphere
2013-10-21 04:29:04

Ocean circulation is responsible for causing more tropical rainfall in the Northern Hemisphere than in the southern part of the world, according to new research published Sunday in the journal Nature Geoscience.

Weather Educartion: Impacts Of The Canadian High Pressure Center
2012-12-29 11:43:39

The Canadian High pressure center shifts into the United States throughout the year and has a major impact on the weather from season to season. In the summer when this high pressure moves in, the temps usually cool off by about 10-15 degrees. For example:  if the temp was 91F in Fargo, it would cool down into the 70s once this high moved in. The high also creates drier weather. In winter when this system moves in the weather pattern is the same in that the temps will drop and the air...

Upper Air Map Identification for July 6, 2012.
2012-07-06 12:00:10

Looking at the upper air map for the entire region from Alaska to the Atlantic Ocean we can identify a few significant features. The first is the deep low height center over Alaska, this is telling us that at 30,000ft the air is rising upwards allowing for the surface low to still be gaining strength. Also if you look to the west of that closed low you will see what is referred to as a jet max getting ready to enter the base of the low height center. This will further amplify the low...

Surface Weather Map Features for July 5, 2012
2012-07-05 10:00:03

The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...

Surface Weather Map Features
2012-07-16 14:20:04

Looking at the weather map above we can see that we have three and four digit numbers on the map. These numbers are known as Sea Level Pressure. They are recorded in MB. Looking at the Northern part of South Dakota we see a number at 995mb while over parts of Maine we see the number closer to 1020mb. So we would say that high pressure is over Maine, while low pressure is over the Dakota’s as our MB numbers show. A surface pressure map can be very useful to a weather forecaster in many...

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...
