The following do not belong to the common disastrous weather in our country: () A. Typhoon B. Cold wave C. Flood and drought D. Ocean.

D Typhoon is mainly caused by strong tropical cyclone in the northwest Pacific Ocean, which mainly affects Guangdong, Taiwan Province, Taiwan Province and Fujian provinces, and is conducive to alleviating the drought in the Yangtze River basin, easily causing strong winds, heavy rains and storm surges.

The cold wave is mainly caused by the strong cold air invaded by Mongolia and Siberia in late autumn, winter and early spring every year, and the consequences are cold, strong wind and frost.

Flood and drought disasters have the greatest impact on the disaster weather in China, which is caused by uneven seasonal distribution of precipitation, great interannual variation, typhoon-induced rainstorm and other reasons.
