Storm

A storm is a kind of severe weather marked by hard wind (a wind storm), or wind transporting some substance through the atmosphere (as in a dust storm, snowstorm, etc). A storm is usually defined as wind measuring 10 or higher on the Beaufort scale, meaning a wind speed of 89 kilometers per hour (55 miles per hour) or more.
