Red Orbit Meteorologist Joshua Kelly In this lesson we will look at different components of a thunderstorm. The first is the thunder which is the audio shockwave that is released just after a flash of lightning occurs. There is a rule of thumb that if you count the seconds after a flash of lightning to the sound of thunder you can determine how far away the thunderstorm is. For example if you count 5 seconds after a flash of lighting to the sound of thunder this would tell you the...

Big Story Weather – March 27, 2012
2012-03-27 05:44:04

Red Orbit Meteorologist Joshua Kelly Big Story news from March 26, 2012: The severe weather was not as active on Monday. There was a few severe thunderstorms that did move through the Northern Plains overnight. Heavy mountain snows found their way through the Northern Sierra Nevada´s and also the Southern portion of the Cascades as the next frontal system began to push onshore. Other big news of the day was the record heat that continues to push its way northward. Big Story news...

Extremely cold cloud top temperatures in thunderstorms are an indication of the strength they possess, and infrared satellite data from NASA revealed a large area of very cold and powerful thunderstorms around the center of Hurricane Dora. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured an infrared image (false-colored) that revealed strong convection (rapidly rising air that forms thunderstorms) and the strong thunderstorms (purple) around the center...

June is Lightning Safety Awareness Month. Lightning is the number two killer of severe weather. Flooding is number one. A lot of people think if it is sunny or maybe just a few clouds around and you hear thunder, it is okay to stay outside until you actually see the lightning. That is not true. If you hear thunder when you are outside, that means that lightning is close enough to strike you! On Thursday, June 23, from 7-8 p.m. EDT, Dr. Richard Blakeslee, atmospheric research scientist at...

System 98A has been bringing rains, gusty winds and churning up the surf along the Arabian Seacoast of west-central India for days, and NASA satellite imagery confirms that it is getting organized now that it has moved into open waters. NASA's Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite captured an image on June 8 at 08:47 UTC (4:47 a.m. EDT) of the hundreds of thunderstorms that make up the low pressure area called System 98A. The low pressure area has now...

Now a remnant low pressure area, former Tropical Storm Carlos continues to move southwest inland over Australia's Northern Territory and dump heavy amounts of rainfall. NASA's Aqua satellite saw some of the high thunderstorms within Carlos over land and extending north into the Timor Sea. The Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite measures cloud-top, sea surface and land temperatures. Those are important factors in determining the strength and power of a...

It's one of the more frustrating parts of summer. You check the weather forecast, see nothing dramatic, and go hiking or biking. Then, four hours later, a thunderstorm appears out of nowhere and ruins your afternoon.Thunderstorms can bring intense rain, hail, lightning and even tornadoes, but "predicting them a few hours out is one of the great problems of meteorology," says Chian-Yi Liu, a postdoctoral researcher at the University of Wisconsin-Madison.And the consequences can be more serious...

Imagine devices that capture electricity from the air "• much like solar cells capture sunlight "• and using them to light a house or recharge an electric car. Imagine using similar panels on the rooftops of buildings to prevent lightning before it forms. Strange as it may sound, scientists already are in the early stages of developing such devices, according to a report presented August 25th at the 240th National Meeting of the American Chemical Society (ACS). "Our research could...

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...

Daily Weather Summary From July 4, 2012

The brief reprieve we saw this week in terms of temperatures has run its course as warmer temperatures will be reinforcing itself into the picture for the latter part of this week and weekend. Wednesday brought many 4th of July festivities and celebrations, as well as temperatures that closed into triple digits for places like Chicago in the mid-west. The 4th of July also featured fireworks in the way of thunderstorms in North Dakota, Wisconsin and Minnesota, continuing the assault of...

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...
