The two-dimensional wind fields associated with a tropical cyclone. Wind distribution is one of the parameters describing tropical cyclone structure. See also hurricane. Wall cloud - A band of deep cumulus that partially or completely surrounds the tropical cyclone center. The air particle velocity measured relative to the earth's surface.
Wind consists of both speed and direction, thus it is a vector.
Since vertical components of the large-scale atmospheric motion are relatively small especially near the earth's surface, meteorologist use the term to denote almost exclusively the horizontal component. Vertical winds are always identified as such. The magnitude of wind. Other regions use ten- minute mean, average or sustained wind speed. Maximum sustained wind is the highest mean wind speed or maximum intensity of a tropical cyclone.
