Causes of cyclone weather

The formation and movement of cyclones and anticyclones have great influence on the weather in vast areas. In the cyclone area, the airflow converges from the outside to the inside, and the airflow rises with the water vapor in the ground air layer, and cools and condenses at high altitude to form clouds and rain. Therefore, the weather in cyclone areas is generally rainy. In the anticyclone area, the airflow diverges from the inside out, mainly downward airflow, usually sunny.
