The vertical range of the Qinghai-Tibet high is from near surface to high altitude.

The vertical range of Qinghai-Tibet high is about 500 hectopascals from near surface to high altitude.

Qinghai-Tibet high, also known as South Asia high or Qinghai-Tibet Plateau geogas system, is a powerful high-pressure system formed and maintained on the Qinghai-Tibet Plateau. This high-pressure system is the most powerful in summer, and its center is usually located in southern Tibet, but its influence can be extended to the eastern and southern parts of China and neighboring countries and regions.

The formation and maintenance of the Qinghai-Tibet high is closely related to the special topography and climatic conditions of the plateau. The Qinghai-Tibet Plateau has high altitude, steep terrain and thin air, which makes the temperature above the plateau higher than that in the surrounding areas. In summer, direct sunlight warms the air over the plateau, which rises to form high pressure. On the other hand, the special topography of the plateau makes it impossible for the humid airflow from the Indian Ocean to directly enter the interior of the plateau.

The lack of plateau water vapor is also an important reason for the formation of Qinghai-Tibet high. The vertical range of the Qinghai-Tibet high extends from the near surface to a height of about 500 hectopascals. In the vertical direction, the high-pressure system includes downward flow area and updraft area. Downdraft zone is located near the center of high-pressure system, while updraft zone is located at the periphery of high-pressure system.

This sinking and rising airflow pattern is helpful to maintain the existence of the Qinghai-Tibet high. The Qinghai-Tibet high has an important influence on the climate and weather in the surrounding areas. Downward flow under high pressure system will cause air compression and temperature rise, which will help to maintain sunny weather. However, when the high-pressure system moves or weakens, it may cause a wide range of rainfall or snowfall. For example, when the South Asian high weakens in summer.

It may lead to the reduction of monsoon rainfall in India, thus affecting agriculture and water resources in India and Bangladesh. The Qinghai-Tibet high not only affects the climate in the surrounding areas, but also may have an impact on the global climate. The study shows that the intensity and location of the Qinghai-Tibet high are related to the summer precipitation in eastern China.

There is a complex relationship between East Asian monsoon and global climate change. Therefore, the study of the Qinghai-Tibet high will not only help to better understand the weather and climate changes in China and its surrounding areas, but also help to deepen the understanding of global climate change. Generally speaking, the Qinghai-Tibet high is a complex and important weather system.

It was formed under the special terrain and climate conditions of the Qinghai-Tibet Plateau, which has an important impact on the climate and weather in the surrounding areas and may have an impact on the global climate. Therefore, the study of Qinghai-Tibet high is an important subject in the fields of meteorology, climatology and earth science.
