The long-term average weather condition in a place is called climate.

1, definition and characteristics

Climate is a description of the long-term (usually 30 years) average weather conditions in an area. Climate includes the average and range of temperature, precipitation, wind speed and sunshine time, which can help people understand the basic weather characteristics of a place, so as to better adapt to and utilize the local environment.

2. Influencing factors

The formation of climate is influenced by many factors, including geographical location (such as latitude, topography and ocean), atmospheric circulation, ocean current, solar radiation and so on. Their interaction determines the climate characteristics of a certain area.

3. Classification and regions

There are various climatic conditions around the world, which can be roughly divided into tropical, subtropical, temperate and frigid climate types. Different climate types correspond to different geographical areas, and each climate type has its own unique characteristics and influences. For example, temperate climate usually has four distinct seasons, while tropical climate is hot and rainy all year round.

The influence of climate on human beings

1, ecological environment impact Climate change has a great impact on the ecological environment. Rising temperatures and melting glaciers lead to rising sea levels, and coastal areas are at risk of flooding; Extreme weather events such as rainstorm, drought and heat wave occur frequently, which destroy the natural ecosystem and affect biodiversity.

2. Economic and social impact

Climate change has a far-reaching impact on global economic and social development; Agriculture, fishery and tourism are directly affected by climate change, and the economic output value may be affected; The uneven distribution of resources and population migration caused by climate change may lead to social inequality and conflict.

3. Health and safety impact

Climate change poses a threat to human health, and extreme weather events may lead to the outbreak and spread of diseases, such as malaria and dengue fever. High temperature and air pollution will also increase the risk of cardiovascular and respiratory diseases; Climate change may lead to political and economic security problems, such as resource competition, international cooperation and geopolitical tensions.
