What are the characteristics of tropical rain forest climate?

Tropical rain forest climate, also known as equatorial rainy climate, is mainly distributed on both sides of the equator (near the equator) 10 latitude. It is hot and rainy all year round, with an average monthly temperature of 25-28℃ and an annual precipitation of over 2000 mm, with even seasonal distribution and no dry season. It mainly appears in Amazon Plain in South America, Congo Basin and Gulf of Guinea in Africa, most parts of Malay Archipelago in Asia and southern Malay Peninsula. Remarkable features: high temperature and rainy, small temperature difference throughout the year. The annual variation of solar radiation is small, because the sun passes through the zenith twice before and after the vernal equinox and autumnal equinox in a year, the annual variation of meteorological elements has double peaks. The average monthly temperature varies between 24-28℃ in a year, and the annual temperature difference generally does not exceed 5℃, especially in the ocean, which usually does not exceed 65438 0℃. The daily variation of temperature is greater than the annual variation, and the daily amplitude can reach 10- 15℃. However, the daily maximum temperature rarely exceeds 35℃, and the daily minimum temperature rarely falls below 20℃. The humidity is high all year round. As far as the lower reaches of the Amazon River are concerned, the annual average relative humidity exceeds 90%. There is abundant precipitation, mostly accompanied by thunderstorms. The annual precipitation reaches 1500-3000mm, and the maximum is over 6000mm in mountainous areas. For example, the annual precipitation in Debenga at the foot of Cameroon volcano in Africa reaches 9470 mm. The seasonal distribution of precipitation is relatively uniform, but there are still obvious differences in individual areas. For example, the Congo River basin in Africa is more obvious than the tropical rain forests in Asia and South America. Continental, some places have less rainfall, such as Libreville, Gabon. The monthly rainfall from June to May is 200-300mm, while it is only 5mm in June and July. In addition, there will also be dry and rainless areas in the ocean, such as Modeng Island in the Pacific Ocean (latitude 4 south and longitude 155 west), with an annual precipitation of only 730 mm. In the alpine region with tropical rain forest climate, the temperature is low, but its annual change is still very small. These areas, from the foot of the mountain to the top of the mountain, can have tropical rain forests or a year-round snow-covered climate, showing a variety of natural landscapes similar to those from the equator to the polar regions, with the most colorful vertical distribution. There are two seasons: drought and rain. The weather is very monotonous. Controlled by the equatorial ocean air mass all the year round, the wind is weak and the seasonal phase remains unchanged. It's basically sultry and sunny every morning, and then the cumulus clouds accumulate thicker and thicker. It rained cats and dogs in the afternoon, and it was a little cold after the rain, and it was the same the next day.
