Is everything warm and humid in Hainan? What are the advantages and disadvantages?

Although Hainan is not big, there are five climates in a Hainan island. According to the classification of chinese national geography, the geographical climate of Hainan Island is divided into five areas: 1, and the northern part is a semi-humid area, including Haikou, Ding 'an, Danzhou, Lingao, Chengmai and a part of Tunchang. In winter, because it is far from the equator, it is often attacked by cold air, which is characterized by wet and cold weather and much rain. 2. The east is a humid area, including Wenchang, Qionghai and Wanning. Facing the vast South China Sea to the east, ocean currents often bring rain, and it often rains in winter, which is the wettest area on the island in winter, especially Wenchang, followed by Qionghai and Wanning. 3. The west is a semi-arid area, including Changjiang River and the East. It is in the lee of Wuzhishan and Sakuragi Ridge, so it seldom rains all the year round, and it is also very dry in winter, but the windy weather in the east is the most in the whole island because it is close to the sea. 4. The south is a semi-arid and semi-humid area, including Sanya, Lingshui, Ledong and Baoting. The climate is the warmest in the whole island, especially in the north and east of Hainan, which is wet and cold in winter, and the south is usually sunny, clear and Wan Li, which is relatively dry. 5. The middle part is a humid mountainous area, including Wuzhishan, Qiongzhong and Baisha. Taking Wuzhishan as the center, it is relatively humid and cold in winter, but the white sand in the leeward area of Wuzhishan is relatively good. The concrete and intuitive climate map of Hainan can be found in Haiju. com。 Reasons for the formation of Hainan's climate: The climate difference in Hainan is related to the direction of the South China Sea monsoon, the barrier of Wuzhishan and the barrier of Niu Ling. The barrier of Wuzhishan in the middle makes the east moist, the middle is moist because of the rainforest, and the west is dry. The barrier in Niu Ling makes the area south of the north latitude 18 line less affected by cold air. When it rains continuously in winter and spring in the northern and central parts of Hainan Island, the southern part of Hainan Island is just in the dry season, which is dry and sunny. Therefore, Hainan is warm as a whole, but the degree of wetness is different. It is humid in the east and middle, and relatively dry in the south and west. Climate difference constitutes the difference of ecological environment in Hainan Island. The warm and humid climate is conducive to the reproduction and growth of animals and plants, so the eastern and central parts are densely forested areas. The green coverage rate in western China is relatively low. As for the climate in Hainan, its advantages and disadvantages are relative to people. Humidity is a disadvantage for rheumatism patients, but it is an advantage for those who want to be beautiful. For the cold regions in Northeast China, the warmth of Hainan is an advantage, so many Northeasters have settled in Hainan. For those who like four distinct seasons, the warmth of Hainan is another disadvantage.
