The differences in climate around the world are mainly manifested in what and what.

The differences in climate around the world are mainly manifested in two aspects: temperature and precipitation.

Climate, a natural science term, is the long-term average state of atmospheric physical characteristics. Unlike the weather, it has stability. Time scales are months, seasons, years, years to hundreds of years. Climate is measured by the characteristics of cold, warm, dry and wet, and is usually characterized by the average value and deviation value of a certain period. The subject of studying climate is climatology.

Climate is the general state of the atmosphere in a certain region of the earth for many years, and it is the comprehensive expression of various weather processes in this period. Various statistics (mean, extreme, probability, etc. Meteorological elements (temperature, precipitation, wind, etc.). ) is the basic basis for expressing climate. Climate is closely related to human society, and many countries have recorded climate phenomena for a long time.

In ancient times, there were 24 solar terms and 72 climaxes. Twenty-four solar terms were established in ancient times, and were later absorbed into taichu calendar law as a supplementary calendar to guide farming. Twenty-four solar terms are not only the time criterion promulgated by successive governments, but also the compass to guide agricultural production and to predict cold, warm, snow and rainy days in people's daily life. The word climate comes from ancient Greek, which means inclination, meaning that the climate in different places is related to the inclination of the sun's rays.

Tropical rain forest climate:

Tropical rain forest climate (also known as equatorial rain forest climate) is characterized by high temperature and rainy all year round. Located near the equator, it extends about 5 ~ 10 from south to north. Its main distribution areas are: Amazon Plain in South America, Congo Basin in Africa, Malay Peninsula and Malay Archipelago.

These areas are located in the equatorial low pressure area, and the airflow is mainly upward, so there are many opportunities for water vapor to condense into rain. It rains all year round, and there is no dry season. The annual precipitation is generally above 2000 mm, and the minimum monthly precipitation is above 60 mm, with frequent thunderstorms. The average temperature in each month is 25 ~ 28℃, and the summer is long all year round, with no seasonal change. The annual temperature is generally below 3℃, and the average daily temperature can reach 6 ~ 12℃.

Several special distributions: eastern Madagascar, northeastern Australia, southeastern Brazil and northeastern Caribbean island countries. In this high temperature and rainy climate all the year round, plants can grow all year round, with diverse tree species, dense vegetation and a wide variety of animals and plants.
