Types Of Lightning
2012-05-10 10:05:27

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and...

Cumulus Clouds
2012-05-07 08:43:06

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...

Hard Rime
2009-07-06 15:49:33

Hard rime is a type of white ice that forms when water droplets found in fog freeze to the outer surfaces of objects. Hard rime is most often found on trees atop mountains and high ridges in winter, when low clouds cause freezing fog. This fog freezes along the windward (sides facing the wind) side of trees, buildings, and any other solid objects. The air temperature needed for hard rime to...

Rain
2009-07-04 16:31:47

Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface....

Nimbostratus
2009-07-04 15:37:27

Nimbostratus clouds are distinguished by a formless cloud layer that is predominantly dark gray in color. "Nimbo" comes from the Latin word "nimbus", meaning rain. It is a cloud that produces rain, and develops a cloud base between the surface and 10,000 feet. These clouds normally have a thickness of 6,500 to 10,000 feet, but can range from 3,500 to 15,000 feet. In rare cases, nimbostratus can...

Stratus
2009-07-04 15:24:37

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...

Cirrus
2009-07-04 15:10:05

Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of...

Cirrocumulus
2009-07-04 15:02:09

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...

Sky

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The...
