A tornado is a meteorologic phenomenon which consists of a column of air spinning violently: a tornado is usually in contact with both the surface of the ground and a cumulonimbus cloud. Tornadoes are formed inside thunderclouds (supercells) several meters above the Earth's surface. The...

Due to the tremendous natural forces involved in the development of a tornado, it turns out almost impossible to place measuring weather instruments inside a tornado to calculate its force. The best method which meteorologists have devised for estimating the intensity of a tornado has...

Tornadoes are vicious weather phenomena that sometimes appear with severe thunderstorms. There are two types of tornadoes, the type spawned by supercell storms and all others, but there are as many varieties of destruction and wild beauty within those types as imagination allows.

Meteorologists are so often wrong in their weather predictions because the wind blows where it wills. No one knows where comes from or where it goes. Wind drives many storms and makes them go in a direction that computer models don't see. Weather prediction has...
How people know that global climate has been changing for millions of years
By: Christyl Rivers
Climate change happens slowly over time. The evidence is in the sedimentary rock, in the dried sea beds, in the fossils found in places of very different climate today. Climate change affects all of life, although its impact is measured in geological time. Therefore, although...
How people know that global climate has been changing for millions of years

For several decades, global climate change has been a phrase the news media and others appear to love using. The idea isn't too hard to grasp, and yet it can cause confusion. People might wonder how anyone can know the extent of the change, especially...

The earth's climate has changed throughout earth's history. There have been periods, such as the glacial periods (ice ages) where earth has been covered by ice or interglacial periods where ice has retreated entirely to the poles or has melted completely. Samples left by ancient...

The solstices occur when the Sun reaches its highest position in the sky as seen from the South and North Poles. The word solstice is derived from the Latin "sol," which means sun and "sistere," meaning to stand still. A solstice is the...
Why is there more humidity at night?
By: Jon Barr
Have you ever been outside on a summer night and wondered why it is so humid? Why glasses will “fog” up? Why you feel like you just got out of a shower at times? It is really a very simple reason that you do...

Both the winter and summer solstices have been an important part of human understanding regarding the changes in seasons for millennia. The differences in the two solstices are central to daily living. Although the importance may have been lost to the modern world, ancient cultures...
