Snowstorms happen when the cold air moves away from the polar regions and collides with warm air. The warm air rises quickly and the cold air cuts underneath it. This causes a huge clouds to form, leading to heavy snowfall.


Rain is a very common type of weather that occurs all over the world. Rain is created when water that was evaporated from earths surface as a gas turns into a liquid as it is condensing in the clouds. When those droplets get to heavy the cloud with open up and the rain will fall back down to the earth.

Teaching you about 10 different types of weather, and how they are formed.



Tornadoes are usually the extreme result of a supercell thunderstorm. During the storm, cold air and warm air combine in a pattern. When the cold air drops the warm air will rise. The warm air eventually twists into a spiral and forms the funnel cloud that we all associate with a tornado.

Hurricanes form when hot tropical waters react with areas of low atmospheric pressure. The water begins to evaporate and condense thus creating a rotation and the center or eye of the storm.

Droughts are caused by lack of rain over a long period of time. They also mainly occur in hot dry areas of land; the area is dry because there is very minimal rainfall.




Highs are usually associated with light winds at the surface and subsidence through the lower portion of the troposphere. The subsidence will dry out an air mass by compressional heating. High pressure typically brings clear skies.

Clear Skies

Squall lines are several thunderstorms that have come together in a line. They usually develop ahead of an advancing front, or between a cold front and a warm front.

Squall Lines

Fog is formed in many ways but one common way is when there is a temperature difference between the ground and the air. When the humidity is high and there is enough water vapor fog is sure to form.


Wind is formed when there is a difference in pressure gradient. Particles move from areas of high concentration to areas of low concentration. So when an area heats up more than another area next to it, the difference in pressure creates wind.


Hail forms when tiny clumps of ice, kept aloft by strong updrafts, get blown through freezing thunderclouds until they are heavy enough to fall to earth.
