What does meteorological disaster not include?

Examples of phenomena not included in meteorological disasters are as follows:

Drought: Although drought is also a weather phenomenon, it is not directly caused by abnormal weather changes. Drought is usually caused by long-term lack of precipitation, which leads to water depletion, soil drying and crop damage. Although drought may lead to famine and other social and economic problems, it is different from meteorological disasters because drought is not directly caused by abnormal weather changes.

Earthquakes: Earthquakes are natural disasters caused by tectonic movements of the earth. Although earthquakes may be related to meteorological factors, such as rainfall and groundwater level, earthquakes are mainly caused by geological factors, which are obviously different from meteorological disasters.

Flood: Although the flood may be caused by extreme weather events, such as rainstorm and hurricane, it may also be caused by other factors, such as land use change and water conservancy projects in the basin. Therefore, flood is regarded as a natural disaster, not just a meteorological disaster.

Nuclear accident: A nuclear accident is caused by an accident at a nuclear energy facility and has nothing to do with meteorological disasters. A nuclear accident may cause a series of environmental and health problems, but it is different from meteorological disasters because it is caused by human activities and technical failures.

Meteorological disasters have the following characteristics:

1, extensiveness: Meteorological disasters often affect a wide range, not limited to a certain region or city. For example, storms, floods, typhoons and other disasters can affect the whole country or region, and even cross national boundaries.

2. Sudden: Meteorological disasters often occur suddenly, and it is difficult to accurately predict and prevent them in time. For example, tropical cyclones, rainstorms, floods and other disasters often escalate rapidly in a short period of time, bringing unexpected disasters to people.

3. Diversity: There are many kinds of meteorological disasters, including rainstorm, flood, typhoon and snowstorm. These disasters may cause different degrees of damage to human life, environment and economy.

4. Relevance: Meteorological disasters are related to other natural disasters and man-made disasters. For example, heavy rain may cause geological disasters such as mudslides and landslides; Drought may cause social and economic problems, such as famine and population migration; Climate change may affect the sustainable development of agriculture, energy and water resources.

5. Periodicity: Meteorological disasters have a certain periodicity, such as heavy rain, floods, typhoons and other disasters are more frequent in some seasons or years. This provides people with opportunities for early warning and prevention, but it also needs to constantly strengthen countermeasures.
