The word for air (vāyu) or wind (pavana) is one of the classical elements in Hinduism. The Sanskrit word Vāta literally means 'blown'; Vāyu, 'blower' and Prāna, 'breathing' (viz. the breath of life, cf. the *an- in animate). Hence, the primary referent of the word is the 'deity of life', who is sometimes for clarity referred to as Mukhya ...

Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in China and Taiwan as meiyu (梅雨), in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Knowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. [16] A short burst of high speed wind is termed a wind gust ; one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval ...
A tailwind is a wind that blows in the direction of travel of an object, while a headwind blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect.
The term "squall" is used to refer to a sudden wind-speed increase lasting minutes. In 1962 the World Meteorological Organization (WMO) defined that to be classified as a "squall", the wind must increase at least 8 metres per second (29 km/h; 18 mph) and must attain a top speed of at least 11 metres per second (40 km/h; 25 mph), lasting at least one minute in duration.
Khamsin, [1] chamsin or hamsin (Arabic: خمسين ḫamsīn, meaning "fifty"), more commonly known in Egypt and Israel as khamaseen (Egyptian Arabic: خماسين ḫamāsīn, IPA: [xɑmæˈsiːn] ⓘ), is a dry, hot, sandy local wind affecting Egypt and the Levant; similar winds, blowing in other parts of North Africa, the Arabian Peninsula [citation needed] and the entire Mediterranean ...
