wind circulationSummary The movement of air is governed by the equations of motion, where the mass of a parcel of air multiplied by its acceleration is equal to the vector sum of the forces acting on the parcel. The forces acting on the parcel are the pressure gradient force, the ...

ocean circulation system. Upwelling isn't the only way out of the deep sea. Any process which encourages vertical mixing will transfer water out of the depths. Water flowing over variable seabed topography can experience strong mixing which is particularly effective where the vertical temperature grad...
European storminess and associated circulation weather types: future changes deduced from a multi-model ensemble of GCM simulations A range of possible changes in the frequency and characteristics of European wind storms under future climate conditions was investigated on the basis of a...

Another possible consequence of global warming is a decrease in the global ocean circulation system known as the “thermohaline circulation” or “great ocean conveyor belt.” This system involves the sinking of cold saline waters in the subpolar regions of the oceans, an action that helps to dr...
Hadley cell, model of the Earth’s atmospheric circulation that was proposed by George Hadley (1735). It consists of a single wind system in each hemisphere, with westward and equatorward flow near the surface and eastward and poleward flow at higher alt
The vegetation mosaic around Kedarnath which results from the varying topographic (altitudinal ranges, slope gradient), climatic (rainfall pattern, wind circulation) and edaphic factors, is dominated by conifers (~50%)23. Sub-alpine vegetation occurs below the elevation of ~3500 m AMSL36.The ...
Wind directions predicted from global circulation models and wind directions determined from eolian sandstones of the western United States--A comparison. In: G. Kocurek (Editor), Late Paleozoic and Mesozoic Eolian Deposits of the Western Interior of the United States. Sediment. Geol., 56: 261-...
1) global wind-circulation pattern 全球风向流动模式2) GCMs 全球环流模式 1. Based on the SWAT(soil and water Assessment Tools) model and four GCMs(General Circulation Models) under three emission scenarios,this study assessed the potential impacts of climate change on water resources in the ...
circulation anomalies over the Asia-African monsoon regions on interdecadal time scale.Just because of the effect of this wave train,there exists an obvious relationship between the droughts occurred in North China from 1965 and the desertification occurred in the Sahelian region of North Africa.More...
