For example, a northerly wind blows from the north to the south . Wind direction is usually reported in cardinal directions or in azimuth degrees . Wind direction is measured in degrees clockwise from due north . Consequently, a wind blowing from the north has a wind direction of 0 °; a wind blowing from the east has a wind direction of 90 °; a wind blowing from the south has a wind direction of 180 °; and a wind blowing from the west has a wind direction of 270 ° . In general, wind directions are measured in units from 0 ° to 360 °, but can alternatively be expressed from - 180 ° to 180 ° . </P> <P> Winds are named for the direction from which they come, followed by the suffix - erly . For example, winds from the north are called "northerly winds" (north + - erly). </P>
