Weather Pack For July 30 2012
2012-08-01 12:22:59

Weather Pack is our way to envision what is happening with the weather and create a weather forecast for a certain area of the United States. Today’s focus is on Southwest Mississippi along the Mississippi River. On the left side we have a Skew-T which is used to help us determine what is happening in the upper levels at our forecast location. On the right side is our morning satellite...

The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such...

Cumulus-nimbus Clouds

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...

The above cloud is known as a towering cumulus cloud or TCU for short. TCU clouds are a form of cumulus clouds. They are the second stage of the cumulus family. The thing that makes these clouds unique is the vertical extent of them. They can extend very high into the atmosphere and sometimes they form in multiple rows. Towering Cumulus clouds can bring waterspouts when they are over the open...

If you look in the photo above you can see the line of Cumulus clouds that appear in the background. These clouds were created by daytime heating and also an unstable atmosphere. The moisture for these clouds was rising from the Pacific Ocean. The darker cloud is the stronger of the cumulus clouds meaning that the majority of the moisture is being absorbed by that cloud. The clouds around this...

Cumulus clouds are white in appearance and are formed when warm moist air near the earth’s surface is forced aloft by day time heating. Cumulus clouds are usually associated with nice weather, however if they continue to grow and get more moisture and instability with them they can turn into Towering Cumulus and CB clouds which would change the weather to increase the chance of seeing...

There are several types of cumulus clouds. Some are only 3,000ft above the ground while others are found above 20,000ft. They range in size from small to very large and have a wide aspect on impacting the weather. Cumulus- These clouds are generally found 3,000ft above the ground and white in color. They are formed by warm air rising from the surface and saturating in the upper levels. These...

Thermal Column
2009-07-18 15:14:24

A thermal column is a column of rising air in lower altitudes of the atmosphere. Thermal columns are created by uneven heating patterns of the Earth's surface from solar radiation. The sun warms the ground, and the air directly above the ground begins to warm. As the warm air expands, it becomes less dense than the air around it and rises. As the warmer air rises, it cools due to its expansion...

A Stratus cloud is a cloud belonging to a class distinguished by horizontal layering with a uniform base. This type of cloud is different from other clouds that are usually taller than they are wide (these are known as cumulus clouds). The term "˜stratus', In Latin, means layer or blanket. Stratus clouds are flat, featureless clouds of low altitude that can vary in color from dark gray to...

Cirrocumulus clouds are high-altitude clouds that mainly occur between 16,000 and 40,000 feet. Like most cumulus clouds, these clouds indicate a vertical and upward transference of atmospheric conditions. Unlike other cirrus clouds, cirrocumulus composition includes super-cooled liquid water droplets. Ice crystals are also present, and usually, the ice crystals cause the droplets in the cloud...

Word of the Day
  • Small missiles, especially grape, canister, fragments of iron, and the like, when fired, as upon an enemy at close quarters.
  • To fire mitraille at.
The word 'mitraille' comes from the Old French 'mitaille', meaning 'small coins', sometimes used to mean 'scrap iron'.
