Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...

Weather Education - Super-cell Thunderstorms
2013-01-13 09:51:18

In this lesson we are going to take a look at super-cell thunderstorms and what they mean and how they impact our daily lives. First, a super-cell thunderstorm is formed from a cumulus-nimbus cloud.  Super-cell thunderstorms are the most advanced form of thunderstorms known on earth. This is because these types of thunderstorms need so many things to come together in the atmosphere at the same time. The first thing they need is the warm moist air at or near the surface. Secondly, is...

Weather Education - Orographic Thunderstorms
2013-01-13 09:40:16

Orographic thunderstorms are formed when the air is pushed up a mountain side. This type of thunderstorm is found only on the windward side of a mountain range. In the United States we would find these types of thunderstorms on the western slopes of the Rocky Mountains and also on the western slopes of the Appalachians. Things that make this thunderstorm important: First of all they only form in certain geographical places on the earth as mentioned above. But they can form anywhere in the...

Cumulus-nimbus Clouds
2014-01-11 00:00:00

The image above shows a Cumulus-nimbus cloud that has an anvil top to it. The reason that can be identified is that the cirrus is in place above the center of the storm. The image below does not have an anvil top yet. The anvil top forms on CB clouds after they reach the height in the atmosphere where they begin to feel the upper level winds becoming too strong for them to continue development vertically. The storm on the right has not felt the upper level winds yet, that is why it lacks the...

Weather Map Identification
2012-07-17 21:51:43

It is very important to understand what you are looking at when working with weather maps. In the image above we are looking at surface wind barbs. Surface wind barbs help us to identify which direction the wind is blowing and also the speed of the wind. If we look in the Northern Gulf of Mexico just to the south of Mississippi we see a wind barb in blue. This wind barb is from the East and it has two full wind barbs which tells us the wind is from the East at 20kts. If you look along...
