Tibetan plateau

Tibetan plateau airborne fine grains produced the enormous amount of loess in the Chinese lowlands. Silt and clay from the glaciers accumulated in these lakes; when the lakes dried at the end of the ice age, the silt and clay were blown by the downslope wind off the Plateau.

This differential warming happens because heating rates differ between land and water. Tibetan plateau turn, air over the land warms faster and reaches a higher temperature than does air over the ocean.

Without the thermal low pressure caused by the heating, there was no monsoon over the Indian subcontinent. Together, these factors mean that the heat capacity of the layer participating in the seasonal cycle is much larger over the oceans than over land, with the consequence that the land warms and cools faster than the ocean.

Archaeological evidence suggests that the colonization leading to the full-time occupation of the plateau occurred much later than the previously thought 30, years ago. The pressure anomaly then causes a steady wind to blow toward the land, which brings the moist air over the ocean surface with it.

Today, Tibet is an important heating surface of the atmosphere.

Thus, while the modern plateau heats the overlying atmosphere, during the Last Ice Age it helped to cool it. With a much lower latitude, the ice in Tibet reflected at least four times more radiation energy per unit area into space than ice at higher latitudes.

Tibetan Plateau Facts

Additionally, the specific heat capacity of liquid water is significantly greater than that of most materials that make up land. Monsoon Natural-colour satellite image of the Tibetan Plateau Monsoons are caused by the different amplitudes of surface temperature seasonal cycles between land and oceans.

Rainfall is then increased by the presence of the moist ocean air. The northern portion, the Changtangis generally too high and cold to support permanent population. History of Tibet Nomads on the Tibetan Plateau and in the Himalayas are the remainders of nomadic practices historically once widespread in Asia and Africa.

Impact on other regions[ edit ] Role in monsoons[ edit ] Main article: In winter, the land cools off quickly, but the ocean maintains the heat longer.

The hot air over the ocean rises, creating a low-pressure area and a breeze from land to ocean while a large area of drying high Tibetan plateau is formed over the land, increased by wintertime cooling.

Temperatures are rising four times faster than elsewhere in China, and the Tibetan glaciers are retreating at a higher speed than in any other part of the world.

Ocean heating is distributed vertically through a "mixed layer" that may be fifty meters deep through the action of wind and buoyancy-generated turbulencewhereas the land surface conducts heat slowly, with the seasonal signal penetrating only a meter or so. The rainfall is stimulated by a variety of mechanisms, such as low-level air being lifted upwards by mountains, surface heating, convergence at the surface, divergence aloft, or from storm-produced outflows near the surface.

Qin Dahe, the former head of the China Meteorological Administrationissued the following assessment in Once they vanish, water supplies in those regions will be in peril.

Animals responded to this shift in climate, with the Javan rusa migrating into India. When such lifting occurs, the air cools due expansion in lower pressure, which in turn produces condensation and precipitation.

Tibetan Plateau

While the world's top mountaineers regularly attempt to summit the forbidding peaks of the Tibetan Plateau, the remote area is home to a rich variety of cultures, from villages in.

Plateau of Tibet, Chinese (Pinyin) Qingzang Gaoyuan or (Wade-Giles romanization) Ch’ing-tsang Kao-yuan, also called Tibetan Highlands or Qinghai-Tibet Plateau, vast high plateau of southwestern China.

The Tibetan Plateau, also known in China as the Qinghai–Tibet Plateau or the Qing–Zang Plateau or Himalayan Plateau, is a vast elevated plateau in Central As. Nov 26,  · The Tibetan Plateau is bounded in the north by a broad escarpment where the altitude drops from around 5, metres (16, ft) to 1, metres (4, ft) over a horizontal distance of less than kilometres (93 mi).

Mar 23,  · According to the Institute of Tibetan Plateau Research, Chinese Academy of Sciences, the Tibetan Plateau “ accommodates the largest tropical glaciological area in the world.” The highest plateau in the world, with an average elevation of over 16, feet, the Tibetan Plateau is surrounded by the highest peaks in the Himalayas.
