However, the huge landmass of the Himalayas restricts the low-pressure zone onto the Himalayas themselves. It is only when the Tibetan Plateau heats up significantly more than the Himalayas that the ITCZ rises abruptly and swiftly shifts north, leading to the bursting of monsoon rains over the Indian subcontinent.
The Tibetan Plateau contains the largest area of low-latitude glaciers and is particularly vulnerable to global warming. Over the past five decades, 80% of the glaciers in the Tibetan Plateau have retreated, losing 4.5% of their combined areal coverage. [46] This region is also liable to suffer damages from permafrost thaw caused by climate change.
At that time the most essential heating surface of the atmosphere – which at present, i.e. interglacially, is the Tibetan plateau – was the most important cooling surface. [17] The annual low-pressure area induced by heat above Tibet as a motor of the summer monsoon was lacking. The glaciation thus caused a breaking-off of the summer ...
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area . Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are ...
That, combined with the rise of the hot air, results in a low pressure area called a thermal low. [1] Over elevated surfaces, heating of the ground exceeds the heating of the surrounding air at the same altitude above sea level, which creates an associated heat low over the terrain, and enhances any thermal lows which would have otherwise existed.
A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]
The Asiatic Low is a low-pressure trough which lies over southern Asia, during early summer. It is located roughly over India , heading over the Bay of Bengal . It is a major action centre for the Northern Hemisphere during that time of the year.
Major fault zones around the Tibetan Plateau showing location of the Altyn Tagh Fault. The Altyn Tagh Fault (ATF) is a 2,000 km long, [1] [2] active, sinistral (left lateral) strike-slip fault that forms the northwestern boundary of the Tibetan Plateau with the Tarim Basin.
