Causes of climate change in a region for a long time or a certain period of time

Up to now, there are different opinions on the reasons that affect climate change in a region for a long time or for a certain period, and it is impossible to accurately explain the influence degree of various factors on climate change. However, it can be asserted that on the whole, natural factors are still the dominant factors that affect climate, and human activities are still not enough to affect the basic attributes of regional climate, let alone cause huge climate changes such as ice age or interglacial period. This passage is intended to show that the basic attributes of regional climate mainly depend on natural factors.

Regional climate refers to the typical weather conditions and climate characteristics of a geographical area for a long time. Its basic attributes mainly depend on the following natural factors:

1, latitude: the temperature near the equator of the earth is high, and the temperature in the polar regions is low. With the increase of latitude, the temperature gradually decreases.

2. Height: The higher the altitude, the lower the temperature, the lower the air pressure, and the more significant the temperature change.

3. Terrain: Different terrains have obvious effects on the climate. For example, mountains block the wind direction, and cold air tends to gather in low-lying areas.

4. Waters: The ocean or lake can adjust the climate. For example, the high pressure area and low pressure area generated above the ocean can guide the water flow.

5. Atmospheric circulation: There are different atmospheric circulation between the tropics, temperate zones and polar regions, such as the tropical low pressure region over the equator and the polar high pressure region in the polar regions.

The interaction of these factors makes the climate in different regions show different characteristics, such as temperature, precipitation, seasons and so on. For example, near the equator, the temperature is high and there is a lot of rainfall, but it is cold and dry in polar regions.

Regional climate characteristics usually include the following descriptions:

1, temperature: refers to the average temperature and temperature change in a certain area within a certain time range. The temperature in different areas is affected by latitude, altitude, topography, atmospheric circulation and other factors.

2. Precipitation: refers to the total annual precipitation and the distribution of annual precipitation in a certain period. Precipitation in different areas is also affected by many factors, such as tropical cyclones, monsoons and ocean circulation.

3. Seasonal variation: refers to the difference of temperature, precipitation, humidity and sunshine hours between different seasons in a certain area. The seasonal variation forms are different in different regions, for example, there is almost no obvious seasonal variation near the equator, while the middle and high latitudes are obviously affected by the seasons.

4. Wind direction and wind speed: refers to the average value and variation of wind direction and wind speed in a certain area. The change of wind direction and speed in different areas is also influenced by many factors such as seasons and topography.

5. Air pressure and weather system: refers to the distribution of air pressure in a certain area and related weather systems, such as high-pressure system, low-pressure system and typhoon. The atmospheric pressure and weather system in different areas are also affected by many factors, such as atmospheric circulation and topography.

Generally speaking, the regional climate characteristics are formed by the comprehensive action of many factors, which have an important impact on human production and life and the natural environment.
