Why does the snow cover of the Tibetan Plateau in winter and early spring have the least effect on the intensity of the monsoon in the south of the Tibetan Plateau? Do temperature and climate change conditions in the Tibetan Plateau affect the monsoon climate?

Asian monsoon systems affect some of the world's most populated regions and affect large parts of Asia and the surrounding oceans. This massive air circulation is mainly due to the significant temperature difference caused by the different heating of the land of Eurasia and the seas around the Indian Ocean and the western Pacific.

Both land and sea influence play a vital role, but disentangling the influence of each has been very difficult. For example, the length of time that current atmospheric conditions influence future climate (the "memory effect") is known to be less than a week: while land and oceanic memory effects are important for seasonal prediction, the specific effect of land conditions is . It is not yet clear to understand

The snow cover of the Tibetan Plateau during winter and early spring has relatively little effect on monsoon intensity for several reasons:

When: Monsoons usually begin to intensify in late spring and early summer, while snow cover on the Tibetan Plateau is at its maximum during winter and early spring. By the time the monsoon arrives, most of the snow has already melted or is melting, so its impact on the monsoon is reduced.

Albedo effect: Snow has a high albedo, which means that it reflects a significant amount of incoming solar radiation into space. However, during the monsoon season, when the sun is high in the sky and solar radiation is at its peak, the effect of snow albedo is reduced compared to other factors affecting monsoon dynamics.

Geographical location: The Tibetan Plateau is located at a higher latitude compared to areas directly affected by the monsoons, such as the Indian subcontinent and Southeast Asia. Therefore, the direct influence of plateau snow cover on monsoon dynamics is somewhat limited.

Atmospheric Circulation Patterns: While the Tibetan Plateau plays a role in influencing regional weather patterns, including the Asian monsoon, its influence is more pronounced at other times of the year, such as the summer months when the plateau warms and generates heat. Is. Low pressure system that helps absorb moist air from surrounding areas.

In general, while the snow cover of the Tibetan Plateau has some influence on the regional climate and weather patterns, its influence on the intensity of monsoon rains during winter and early spring compared to other factors such as ocean temperature, atmospheric circulation patterns , and contrast of land and sea temperature

The vast Serbian plateau of Russia creates the cold air mass centers of the Northern Hemisphere winter. This air mass spreads to lower latitudes due to the rotation of the earth and the surface topography that creates different air currents and cold waves. The Tibet region is a high altitude region and is located at a lower latitude, so the ability for cold air masses to form and affect the lower regions is almost non-existent.
