What's the weather like in China when the anticyclone controls most of China? Why is it cold? )

Anti-cyclone refers to the Asian high, which is formed due to the difference of thermal properties between land and ocean. In winter, the temperature in mainland China drops rapidly, with low temperature and high pressure. In fact, it is a high-pressure system formed by the continuous accumulation of cold air. Cold air comes from high latitudes or the Arctic Ocean, so it is cold.
