What are the common meteorological disasters?

Question 1: What are the common natural disasters and meteorological disasters: landslides, mudslides and earthquakes?

Meteorological disasters: cold wave, sandstorm, drought and rainstorm.

1 month: cold wave, freezing injury, heavy snow, blizzard, etc. April: Spring drought in North China and Northwest China, rainstorm, flood and hail in North China. July: Meiyu, drought and flood, typhoon in the Yangtze River basin.

Question 2: What are the main meteorological disasters? Types of Meteorological Disasters in China

Drought is the main meteorological disaster in China. In some areas, although there are certain moisture conditions and even abundant precipitation, which can meet the needs of a large number of people and economy, if the precipitation is abnormally low for a long period of time (months or even years), it will not be enough to maintain the people's living and production needs in this area, resulting in economic losses and even death. This is the so-called drought event. Drought is widely distributed, not only in rainy areas but also in semi-arid areas.

Drought is the largest meteorological disaster in China, with the widest and most serious impact. Drought is widely distributed in China, but the degree is different. Relatively speaking, droughts are most frequent in North China, Loess Plateau, Hexi Corridor and Sichuan Basin.

Drought will also cause some secondary disasters, such as forest and grassland fires and pests and diseases in agricultural and forestry disasters; Soil desertification in geological disasters.

Rainstorm is one of the main meteorological disasters in China. In ancient books of China, continuous rainstorm is usually recorded as "rain" and "rain". "Intermittent rain is like a note" and "continuous rain" is a continuous rainstorm. Rainstorm is one of the meteorological disasters. It is a large amount of accumulated water caused by long-term precipitation or instantaneous heavy precipitation (such as rainstorm, heavy rainstorm), which leads to flash floods, river flooding and waterlogging, resulting in crop failure or failure, traffic and communication obstruction, shipwreck, human and animal diseases and casualties. This kind of disaster is called rainstorm.

China is one of the countries with more rainstorms in the world, with concentrated rainfall and high intensity. Especially in northern China, rainfall often reaches or exceeds the annual average rainfall within a few days.

China has a vast territory and complex terrain, and most areas belong to a typical monsoon climate, so the distribution of rain and waterlogging has obvious regionality and timeliness. Rain and waterlogging mainly affect the eastern and southern regions of China, especially the east of Daxing 'anling-Taihang Mountain-Wuling Mountain. There is little rain in the west of China, and only Sichuan is a rainy and waterlogged area. The temporal distribution characteristics of rain and waterlogging in China are early in the south and late in the north.

The secondary disasters of rain and waterlogging are: pests and diseases in agricultural and forestry disasters; Collapse, landslide and debris flow in geological disasters; Flood, waterlogging, huge waves and storm surges in hydrological disasters.

◆ Tropical cyclone is one of the major meteorological disasters in China. It is a cyclonic vortex that occurs in tropical or subtropical oceans. Because of different regions, the names are different. Typhoons occur in the Pacific Northwest and the South China Sea. Hurricanes occur in the Atlantic Ocean, the Gulf of Mexico, the Caribbean Sea and the eastern North Pacific Ocean. Tropical storms occur in the Indian Ocean and the Bay of Bengal. Australia calls tropical cyclones "powerful?" Power. " According to the regulations of China Meteorological Bureau, China renamed "Typhoon" as "Tropical Cyclone".

Although tropical cyclones have different names in different places, they do the same harm. It is not only human life and property and huge wind speed, but also its huge waves, heavy rains and storm surges are extremely destructive, so it is a very destructive weather system.

There are about 60 tropical storms (including typhoons and hurricanes) around the world every year, of which about 76% occur in the northern hemisphere. China is one of the few countries most seriously affected by tropical cyclones in the world. On average, there are about 7 tropical cyclones landing in China every year, which mainly affect Wuyi Mountain, east of Taihang Mountain, especially the southeast coast and sea area.

Typhoon was called "hurricane" in ancient China. It is the main source of precipitation, wind disaster, tidal disaster and flood in the coastal areas of China. Therefore, tropical cyclones have both advantages and disadvantages. On the one hand, tropical cyclone process can bring abundant precipitation and alleviate local drought. On the one hand, there are many secondary disasters caused by tropical cyclones, such as collapse, landslide and debris flow in geological disasters; Flood, waterlogging, huge waves and storm surges in hydrological disasters.

◆ Cold wave and freezing disaster

? Cold wave: It is one of the major meteorological disasters in China. It is a strong cold air accumulated in high latitudes, which quickly invaded China southward, causing a wide range of severe cooling, accompanied by strong winds, rain and snow, freezing and other disasters. This weather process is called cold wave or strong cold air. Cold wave is the main meteorological disaster affecting China, which lasts from September to May of the following year, and the severe seasons are spring and autumn.

? Freezing disaster: when the temperature drops abnormally, it often causes human and animal casualties, and many objects are deformed and broken, which leads to some accidents, resulting in human and animal casualties and economic losses. This phenomenon is called freezing disaster.

Freezing injury is also the main meteorological disaster in China. ...................................................................................................................................................................... & gt

Question 3: What are the types of natural disasters: drought, rainstorm, flood, typhoon, cold wave, etc.

Geological disasters: mainly include earthquakes, landslides, mudslides, collapses, ground collapses, ground fissures, etc.

Marine disasters: storm surge, tsunami, waves, sea ice, red tide, etc.

Biological disasters: diseases, pests, weeds, rodents, etc. Forest fires and grassland fires are also biological disasters in a broad sense.

Question 4: What are the disastrous weather? Meteorological disaster refers to the direct or indirect damage caused by the atmosphere to human life and property, national economic construction and national defense construction. Natural disasters will cause losses of millions to tens of billions of yuan, and also cause countless casualties in disaster areas.

Meteorological disaster is one of natural disasters. It mainly includes tropical storms in Asia, typhoons in coastal cities of China, drought, high temperature, mountain torrents, thunderstorms and sandstorms in northern China. Hurricanes, tornadoes, hail and heavy rain (snow) are common in North America. China is one of the few countries with frequent natural disasters in the world. There are many kinds of disasters and the losses are very serious.

Question 5: What are the common disastrous weather affecting China? The main disastrous weather includes floods, droughts, cold waves and typhoons. Meiyu is a special weather, and rainfall is normal weather.

There are more than 20 kinds of meteorological disasters, mainly including the following types:

(1) rainstorm: mountain torrents, river flooding and urban water accumulation;

(2) Rain and waterlogging: waterlogging;

(3) Drought: drought in agriculture, forestry and grassland, and water shortage in industry, cities and rural areas;

(4) Dry-hot wind: dry-hot wind and foehn wind;

(5) High temperature heat wave: extreme heat and high temperature, human diseases, burns, and crop ripening;

(6) Tropical cyclones: gale, rainstorm and flood;

(7) Cold damage: crops, livestock and fruit trees are harmed by strong cooling and low temperature;

(8) Freezing injury: frost, crop and livestock freezing injury, water pipes and oil pipes freezing injury;

(9) Freezing rain: wires, branches and roads are frozen;

(10) Freezing: rivers, lakes and seas freeze, and roads freeze after rain and snow;

(1 1) Snow damage: snowstorm, snow;

(12) Hail disaster: destroying crops and houses;

(13) Wind disaster: falling trees, reversing houses, reversing cars and reversing boats;

(14) Tornado: local destructive disaster;

(15) Lightning: lightning casualties;

(16) Continuous rain (plum rain): it is not conducive to crop growth and development, grain mildew, etc.

(17) dense fog: human diseases and traffic jams;
