What is the weather system of dusty weather?

(1) The sandstorm weather in northern China is mainly formed by the cold front weather system. According to the diagram analysis, A is a southern hemisphere cyclone B is a northern hemisphere cyclone C is a warm front D is a cold front.

(2) The characteristics of surface environment in sandstorm-prone areas in China mainly include: arid and semi-arid areas; Deserts are widely distributed; The surface vegetation is seriously damaged.

(3) There is little precipitation and dry climate in northern China in spring; The temperature in the northern region rises rapidly and evaporates vigorously; Coupled with sparse vegetation and frequent windy weather, spring is the high season of sandstorms in China.

(4) The main hazards of sandstorm are: intensifying land desertification; Causing serious pollution to the atmospheric environment; Causing great damage to the ecological environment; Farmland and pasture are buried, which seriously affects the production of agriculture and animal husbandry; It has an important impact on infrastructure such as transportation and power supply lines; Affect people's travel; It affects human health and causes serious losses to people's lives and property.

So the answer is:

( 1)D

(2) Arid and semi-arid areas; Deserts are widely distributed; Sparse vegetation

(3) There is little precipitation in spring and summer in northern China, and the climate is dry; The temperature in the northern region rises rapidly and evaporates vigorously; Vegetation is scarce; There are often cold front weather system activities and strong winds.

(4) Intensifying land desertification; Causing serious pollution to the atmospheric environment; Causing great damage to the ecological environment; Farmland and pasture are buried, which seriously affects the production of agriculture and animal husbandry; It has an important impact on infrastructure such as transportation and power supply lines; Affect people's travel; It affects human health and causes serious losses to people's lives and property.
