In meteorology, prevailing wind in a region of the Earth 's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface at any given time. A region's prevailing and dominant winds are the result of ...
Sea level. This marker indicating sea level is situated between Jerusalem and the Dead Sea. Mean sea level ( MSL, often shortened to sea level) is an average surface level of one or more among Earth 's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datum – a standardised ...
Topography of Europe. Some geographical texts refer to a Eurasian continent given that Europe is not surrounded by sea and its southeastern border has always been variously defined for centuries. In terms of shape, Europe is a collection of connected peninsulas and nearby islands. The two largest peninsulas are Europe itself and Scandinavia to ...
The foreground shows the transition from trees to no trees. These trees are stunted in growth and one-sided because of cold and constant wind. The tree line is the edge of a habitat at which trees are capable of growing and beyond which they are not. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate ...
Thermohaline circulation ( THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [1] [2] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea water.
Animation of circulation around ice shelves of Antarctica. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [1]
Rainfalls from the southern South Asian monsoon do not make it far past the Himalayas (seen by the snow line at the bottom), leading to an arid climate on the leeward (north) side of the mountain range and the desertification of the Tarim Basin (top). A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the ...
This barrier jet can increase the low-level wind by 45%. [51] Wind direction also changes because of the contour of the land. [52] If there is a pass in the mountain range, winds will rush through the pass with considerable speed because of the Bernoulli principle that describes an inverse relationship between speed and pressure. The airflow ...
