The following options do not belong to meteorological disasters in China: A. Drought and flood B. Debris flow C. Cold wave D.

Analysis of test questions: precipitation in China is mainly affected by southeast monsoon and southwest monsoon. Whether the monsoon comes early or late, it is easy to cause floods. The monsoon comes early and it is easy to flood. When the monsoon comes late, it is easy to produce drought. Typhoon is an atmospheric vortex originating from the tropical ocean surface, which will bring a lot of precipitation and cause waterlogging or other damage. Cold wave is a large-scale intense cold air activity. It is caused by strong cold air and high pressure activities. Harm-it harms agriculture, animal husbandry and transportation, and the north is often accompanied by sand blowing and sandstorm weather. These are meteorological disasters that are easy to encounter in China. Debris flow refers to the landslide caused by heavy rain, snow disaster or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain, carrying a lot of sediment and stones. Debris flow has the characteristics of strong suddenness, fast velocity, large flow, large material capacity and strong destructive power. The factors affecting the formation of debris flow are very complicated. They include lithologic structure, topography, soil layer vegetation, hydrological conditions, climate and rainfall. Debris flow is not a meteorological disaster but a geological disaster.
