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 ...
The ITCZ is visible as a band of clouds encircling Earth near the Equator. The Intertropical Convergence Zone ( ITCZ / ɪtʃ / ITCH, or ICZ ), [1] known by sailors as the doldrums [2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the ...
Fjord. In physical geography, a fjord or fiord ( / ˈfjɔːrd, fiːˈɔːrd / ⓘ [1]) is a long, narrow sea inlet with steep sides or cliffs, created by a glacier. [2] Fjords exist on the coasts of Antarctica, the Arctic, and surrounding landmasses of the northern and southern hemispheres. [3]
The term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.
Tropical cyclones which cross the subtropical ridge axis into the westerlies recurve due to the increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere . The westerlies are strongest in the winter hemisphere and times when the pressure is lower over the ...
The reference to "a Chinook" wind or weather system originally meant, to euro-American settlers along the Pacific Northwest coast, a warming wind from the ocean blowing into the interior regions of the Pacific Northwest of the North America. A strong föhn wind can make snow one foot (30 cm) deep almost vanish in one day. [6]
The North Atlantic Oscillation ( NAO) is a weather phenomenon over the North Atlantic Ocean of fluctuations in the difference of atmospheric pressure at sea level (SLP) between the Icelandic Low and the Azores High. Through fluctuations in the strength of the Icelandic Low and the Azores High, it controls the strength and direction of westerly ...
