The dust in the air could too trigger rain! And that is just what’s bringing rain over South Asia’s Tibetan Plateau, according to NASA. This is how it happens:
Very small dust particles called aerosols blow in from desert regions and collect in the atmosphere over the plateau’s slopes early in the region’s monsoon season, helping trigger rainfall.
A monsoon is a seasonal shift in wind direction that alternately brings very wet and then very dry seasons to India and much of Southeast Asia.
A research scientist at NASA’s Goddard Space Flight Center, Greenbelt, Md. and his team has used computer models to study the aerosols. Aerosols were found in the form of dust that is lofted from the desert surface and transported to the monsoon region. It is capable of heating the air by absorbing the radiation of the sun. Thus, it alters the Asian monsoon water cycle.
