Consequently, a wind blowing from the north has a wind direction referred to as 0° (360°); a wind blowing from the east has a wind direction referred to as 90°, etc. Weather forecasts typically give the direction of the wind along with its speed , for example a "northerly wind at 15 km/h" is a wind blowing from the north at a speed of 15 km ...
A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Presented in a polar coordinate grid, the wind rose shows the frequency of winds blowing from particular directions.
Wind direction is usually expressed in terms of the direction from which it originates. For example, a northerly wind blows from the north to the south. [8] Weather vanes pivot to indicate the direction of the wind. [9] At airports, windsocks indicate wind direction, and can also be used to estimate wind speed by the angle of hang. [10]
In the Pacific Ocean, the full wind circulation, which included both the trade wind easterlies and higher-latitude westerlies, was unknown to Europeans until Andres de Urdaneta's voyage in 1565. [4] The captain of a sailing ship seeks a course along which the winds can be expected to blow in the direction of travel. [5]
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
However, when the wind is blowing, it will continuously blow that blanket of heat away from our bodies, leaving the skin exposed to the cold air. The faster the wind speed, the faster our body ...
With high wind speeds forecasted in the state, it'll feel much colder than the actual temperature. Here's what to know about wind chill and what the term means.
The association of geographic direction with wind was another source. [3] It was probably farming populations, attentive to rain and temperature for their crops, that noticed the qualitative differences in winds – some were humid, others dry, some hot, others cold – and that these qualities depended on where the wind was blowing from.
