Weather of cyclone passing area

(1) As can be seen from the figure, the weather system has low central air pressure, high ambient air pressure, heavy short-term rainfall, typhoon eye structure and high central wind speed. The weather system is a cyclone, and there may be violent storms in the passing area.

(2) Typhoons are mostly formed on the tropical ocean surface, which has a great impact on the southeast coast of China, affecting navigation and fishing, causing houses to collapse, causing floods, flooding farmland, and destroying electricity, communications, transportation, etc. It has the advantage of alleviating the drought in the summer drought season in the south of the Yangtze River.

So the answer is:

(1) The air pressure in the center of the cyclone is low, the air pressure around it is high, short-term heavy rainfall, typhoon eye structure, strong central wind speed and violent storms.

(2) The southeast coast of tropical ocean affects navigation and fishing, causing houses to collapse, causing floods, flooding farmland, and destroying electricity, communications and transportation. Relieve the drought.
