The wind is the current of air in the atmosphere blowing on the surface of the Earth. The main principle concerning air currents is the shifting of atmospheric pressure. The wind blows from the area of high atmospheric pressure to the size of low atmospheric pressure. The wind has different types and forms depending on its speed, such as hurricanes and whirlwinds. The direction and speed of wind are often measured by an anemometer.
Winds play a vital role in spreading pollens and the continuation of flora life on Earth. In the 57th ayah of Sūrah al-A’raf, Allah Subhānahū says: “And it is He who sends the winds as good tidings before His mercy until, when they have carried heavy rainclouds, We drive them to a dead land and We send down rain therein and bring forth thereby [some] of all the fruits (and crops). Thus, will We bring forth the dead (from their graves); perhaps you may be mindful.”
Winds are named according to the areas they prevail and the reasons they occur. The permanent winds that constantly blow throughout the year depending on the movement of the atmosphere are as follows: Polar easterlies which travel towards the Poles; Westerlies which blow between 40 degrees and 60 degrees latitudes towards the west. The north wind blows in the Northern hemisphere in the northeast direction; the winds that blow in the Southern hemisphere in the southeast direction are easterly winds…or trade winds. They permanently travel from the high-pressure areas between 30 degrees north and 30 degrees southern latitude towards the low-pressure areas at the Equator.
In Turkey, north wind, south easter, easterly wind and Lodos prevail. Lodos blowing from the southwest direction are hot. The Poyraz, (north wind) prevails in the Mediterranean, Black Sea and Thrace regions, and it usually brings rain in spring.
