The term "typhoon" refers to a tropical, cyclonic storm that originates in the western Pacific Ocean (in the Atlantic, this type of storm is referred to as a hurricane). Typhoons are characterized by large masses of clouds, which spiral around a central point, or eye. Infamous for their destructive powers, typhoons can generate winds of more than 75 miles/hour and have been known to cause flash floods with their intensive rainfall. Buildings and infrastructure, trees and other vegetation, watercraft and water operations, and human and animal life can all be affected.
