Wind roses are tools used to display the direction of the prevailing wind. Knowledge of the prevailing wind allows the development of prevention strategies for wind erosion of agricultural land, such as across the Great Plains. Sand dunes can orient themselves perpendicular to the prevailing wind direction in coastal and desert locations ...
The term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". [2] The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.

The westerlies, anti-trades, [2] or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes (about 30 degrees) and trend towards the poles and steer extratropical cyclones in this general manner. [ 3 ]
A wind atlas contains data on the wind speed and wind direction in a region. [1] These data include maps , but also time series or frequency distributions . A climatological wind atlas covers hourly averages at a standard height (10 meters) over even longer periods (30 years) but depending on the application there are variations in averaging ...
Wind direction is generally reported by the direction from which the wind originates. For example, a north or northerly wind blows from the north to the south; [1] the exceptions are onshore winds (blowing onto the shore from the water) and offshore winds (blowing off the shore to the water). Wind direction is usually reported in cardinal (or ...
Whether you're heading home or going somewhere fun to celebrate New Years Eve, the busy holiday travel period continues, and weather may be a factor. For some, snow, rain, thunderstorms, fog, even ...

By controlling the position of the Azores High, the NAO also influences the direction of general storm paths for major North Atlantic tropical cyclones: a position of the Azores High farther to the south tends to force storms into the Gulf of Mexico, whereas a northern position allows them to track up the North American Atlantic Coast.
