A storm is the result of the air that upraises rapidly and takes with it an abundant amount of moisture. Storms are created when a center of low pressure develops with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds.

A storm may be marked by strong wind, hail, thunder and/or lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc. Storms generally lead to negative impacts to lives and property.

The storms called Frontal Storms, are just one way in which air is pulled up into the atmosphere. A front is a boundary between warm air (to the South), and cold air (to the North). There are also tropical storms, which have very low pressure and wind rotation, and they usually develop in the tropics. Actually a tropical storm is classified in the same way as a hurricane. The wind speed is a determining factor; wind speeds within a tropical storm must be between 39 and 73 miles per hour (or 63 to 118 kilometers per hour).
