What factors affect weather changes?

The rotation and revolution of the earth, light, temperature, ground water sources, vegetation, human influence, such as pollution, geological movements, the influence of other celestial bodies, such as the moon, the sun, etc., and the distance between the sun and the earth

(The influencing factors of climate mainly include solar radiation, atmospheric circulation, ground conditions (terrain, reflectivity, heat capacity), ocean currents, etc. Among them, solar radiation determines the climate zone, atmospheric circulation directly restricts the climate type, and the ground Conditions and ocean currents change the main rules of climate distribution. The causes of the main climate are relatively easy to analyze. Let’s analyze several local climates.

1. Similar to the Tropic of Cancer, the tropical desert climate of Africa appears. The reasons for the tropical monsoon climate in South Asia and the subtropical monsoon climate in southeastern my country are: North Africa is affected by tropical continental air masses and trade winds from the interior of the continent, making it hot and dry all year round, South Asia is affected by the tropical monsoon, and southeastern my country is affected by the subtropical monsoon.

2. The cause of the Thar Desert in South Asia: controlled by the subtropical high pressure zone, the southwest monsoon is not easy to reach, and the original vegetation is destroyed.

5. The higher the latitude, the greater the annual temperature range. The reason is that the higher the latitude, the greater the annual change in the height of the noon sun, the greater the annual change in day and night length, and therefore the greater the annual temperature range; the opposite is true at low latitudes, the further away from the sea, the greater the annual temperature range. : The heat capacity of land is smaller than that of the ocean. It heats up quickly in summer and has a higher temperature than the ocean. It cools down quickly in winter and has a lower temperature than the ocean. Therefore, the annual temperature range is greater than that of the ocean. The coastal area is more affected by the ocean than the inland annual range.

6. The reasons for the large temperature difference between the north and the south in winter in my country are: my country has a large latitude span, and the direct point of the sun in winter is in the southern hemisphere. The farther south our country goes, the greater the height of the sun at noon and the longer the day, so the farther south we get The more solar radiation, coupled with the frequent southward movement of winter monsoons, the greater the impact on northern my country.

7. The reasons for the generally high temperatures in summer in my country are: the direct point of the sun is in the northern hemisphere, and although the height of the sun at noon is smaller in the north than in the south. Some, but the daytime is longer than that in the south, and the solar heat received is not much less than that in the south.

8. The reason why my country’s winter temperature is lower than that in other areas at the same latitude is that it is affected by the strong Mongolian-Siberian cold. Affected by high pressure (or affected by winter monsoon).

9. The reason why India has higher temperatures than my country at the same latitude is the high mountain barrier (the tall Himalayas block the cold air flow from the south)

10. The reasons for the formation of tropical rainforest climate in the southeastern coast of Brazil, northeastern Australia, and eastern Madagascar: mainly due to the influence of terrain (mountain), on the windward slope of the southeast trade wind, and secondly, the warm current passing along the coast.

11. Is there any forest belt on the southern slope of Tianshan Mountains: No, the reason is: leeward slope, less precipitation

12. The reason why Europe has a larger oceanic climate than North America is that Europe lacks the height extending from north to south. In the large mountainous system, the westerly wind from the ocean can penetrate deep into the interior of the continent. Affected by the shape of the land and the power of ocean currents, the west coast of Europe is greatly affected by the warm current.

13. The cause of the Patagonia Desert in southern South America: Earth. It is located in the temperate zone, with prevailing westerly winds. It is on the east side of the Andes Mountains, on the leeward slope, and receives little precipitation.

14. The reason why the subarctic coniferous forest is more southerly on the southern edge of the east coast of the continent: mainly because there is a cold current on the east coast and a warm current on the west coast; secondly, the east coast is affected by the wind from the interior of the continent, and the opposite is true on the west coast.

15. The annual temperature range of the Qinghai-Tibet Plateau is smaller than that of plains and basins at the same latitude in my country. The reasons are: the large plateau at low latitudes is cooler in summer due to its high altitude; in winter due to the low latitude and the influence of high terrain The cold airflow that affects the south is not affected, and the temperature is not too low; the diurnal range is large. The reason is: the density of the atmosphere is small at high altitudes, and the insulation and weakening effects of the atmosphere are low, so the temperature rises quickly during the day and cools down quickly at night.

16. The diurnal variation of temperature: the higher the latitude, the smaller it is. The reason is: mainly because the diurnal variation of the sun's altitude is small. The relationship between the diurnal temperature range and the weather and land and sea is that the diurnal range of temperature is smaller on cloudy days than on sunny days, and the diurnal range of temperature in the inland is larger than that of the coastal areas. The diurnal temperature range of the mountaintops is smaller than that of the plains below the mountains, and the annual temperature range is also smaller.

17. The East African plateau area where the equator passes through mainly has a savanna climate, and the main influencing factor is terrain.
