Where does the wind in Thailand come from, what winds blow and what influences the climate?

Thailand has a tropical monsoon climate. There are three seasons in a year, namely hot season (from mid-February to mid-May), rainy season (from late May to mid-June 10) and cool season (1mid-October 165438 to mid-February of the following year). The annual temperature is not lower than 18℃, and the temperature difference is between 38℃- 19℃. The humidity is between 82.8% and 66%. Take Bangkok as an example. In the hottest April, the temperature can be as high as 37℃, with scorching sun and sultry air. Especially in April, sometimes it even exceeds 40 degrees. At the same time, don't forget to bring a hat and sunglasses to keep out the sun. It's cold in the north, and it's chilly in the north of Chiang Mai and the mountains at night. Be sure to carry a thick coat with you.

Cool season: 165438+ 10 to February of the following year, affected by the cool northeast monsoon. Although the weather is dry during the day, it will be a little cold at night, so it is best to prepare a long-sleeved coat. At this time, the probability of rainfall in northern Thailand is small, and the lowest temperature can reach below 10 degrees. It is common that it doesn't rain for two months, but there are bottles and cans of water in front of every household. Even so, it is still the most comfortable day of the year. The highest temperature is 40-42℃ in March-May. From July to September, due to the influence of southwest monsoon, it is rainy season. There were several violent short-term showers in the afternoon, ranging from a few minutes to several hours. Remind you not to forget to prepare umbrellas and other rain gear when you go out! However, the Thai people never regard the flood as a disaster, and call it "the top of the ear of rice". On the contrary, they are grateful.

From June 5438+ 10 to February 65438+2, tropical cyclones occasionally attacked eastern Thailand from the South China Sea via Indochina Peninsula, but the tropical cyclones formed in Siam Bay were few and weak.

1, the temperature is high all year round, the annual average temperature is above 20℃, and the most Leng Yue in winter is generally above 18℃ for half a year. The alpine plateau in the north blocked the invasion of cold air to the south, which made the temperature in this area relatively high for half a year in winter.

2. The annual precipitation is large, which is obvious in dry and wet seasons, and the precipitation is concentrated in summer. In summer, under the control of equatorial ocean air mass, there is more convective rainfall, and tropical cyclones bring a lot of precipitation, resulting in more rainfall in summer than in tropical dry and wet seasons. On some windward coasts, due to the influence of topography, the summer precipitation even exceeds that in the equatorial rainy climate zone. The annual precipitation is generally above 1, 0,500 ~ 2,000 mm. Winter is controlled by the dry northeast monsoon, and precipitation is scarce.

3. In the obvious dry season, the northeast monsoon issued by the land high pressure flows into the equatorial convergence zone on the ocean. In the rainy season, the southwest monsoon from the subtropical high in the southern hemisphere flows into the Tal low.

4. Tropical cyclones prevail. Synchronized with the "summer monsoon", tropical cyclones prevail from mid-May to mid-September every year.
