Etesian (Greek name) or Meltem (Turkish name) (northerly across Greece and Turkey) Euro (a warm and usually moderate wind from Africa that reaches the Ionian coast of Italy) Euroclydon (a cyclonic tempestuous northeast wind in the Mediterranean) Föhn or foehn (a warm, dry, southerly wind off the northern side of the Alps and North Italy.
A difference in air pressure causes an air displacement and generates the wind. The Coriolis force deflects the air movement to the right in the northern hemisphere and the left in the southern one, which makes the winds parallel to the isobars on an elevation in pressure card. [1] It is also referred as the geostrophic wind. [2]
A valley exit jet is a strong, down-valley, elevated air current that emerges above the intersection of the valley and its adjacent plain. These winds frequently reach speeds of up to 20 m/s (72 km/h; 45 mph) at heights of 40–200 m (130–660 ft) above the ground.
The rising air creates a low pressure zone near the equator. As the air moves poleward, it cools, becomes denser, and descends at about the 30th parallel, creating a high-pressure area. The descended air then travels toward the equator along the surface, replacing the air that rose from the equatorial zone, closing the loop of the Hadley cell. [3]
It is caused by the rising air motion of a large-scale flow of moist air across the mountain ridge, resulting in adiabatic cooling and condensation. In mountainous parts of the world subjected to consistent winds (for example, the trade winds ), a more moist climate usually prevails on the windward side of a mountain than on the leeward or ...
This alphabetically arranged list of air forces identifies the current and historical names and roundels for the military aviation arms of countries fielding an air component, whether an independent air forces, a naval aviation, or army aviation units. At the end is a separate list of no longer existent nations that once operated air forces.
Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 205 listed states can be divided into three categories based on membership within the United Nations System : 193 UN member states , [ 1 ] two UN General Assembly non-member observer ...
