Briefly describe the typical cold and high pressure weather model.

Answer: Front weather of cold high pressure: located at the back of cold front, the temperature drops sharply, the air pressure rises, and the northerly wind sometimes produces bad weather such as rain and snow, causing big waves on the sea.

Weather in the middle of cold and high pressure: the air pressure is high, the temperature rises somewhat, and it is dry, cold, sunny, breezy, and partly cloudy, which is easy to produce radiation fog. The harbor controlled by cold and high pressure forms radiation fog).

Weather behind the cold high pressure: southerly wind (3-4). The temperature rises and rises, similar to warm front weather. After entering the sea, it changes, and rain or stratus clouds often appear in advection fog and Mao Mao.
