Xiamen has a subtropical maritime monsoon climate, which is mild and rainy. The annual average temperature is about 265,438+0℃, with no severe cold in winter and no intense heat in summer. The annual average rainfall is about 1200mm, with the maximum rainfall from May to August every year, and the wind force is generally 3-4, and the dominant wind force is the northeast wind. Due to the temperature difference airflow in the Pacific Ocean, it is affected by 4-5 typhoons every year on average, mostly in July-September.

Climatic characteristics of subtropical ocean monsoon;

1, the annual temperature difference is small, and the maximum Leng Yue is below 25 degrees Celsius. The daily temperature difference is also relatively small.

2. There is a lot of precipitation in the whole year, and it is concentrated in summer and autumn. There is no obvious dry season, and there is often topographic precipitation.

Extended data:

Xiamen is dominated by coastal plains, terraces and hills. Xiamen's topography inclines from northwest to southeast, and there are various types of topography, including Zhongshan, low mountains, high hills, low hills, terraces, plains and beaches. There are many middle and low mountains in the northwest, among which Genting Mountain, located at the junction of Tongan and Anxi, is the highest mountain in the city with an altitude of 1 175.2 meters. From northwest to southeast, there are high hills, low hills, terraces, marine plains and beaches in turn, and Xiamen Island and Gulangyu Island in the south. Genting Mountain is the highest peak in Xiamen, Genting Rock is the highest peak in Xiamen Island, and Sunlight Rock is the highest peak in Gulangyu Island.

The formation background of subtropical maritime monsoon climate;

Tropical maritime monsoon climate, located on the windward slope of the trade wind area, prevails all year round, and warm currents often flow through the east coast, which is of great oceanographic significance.

The land area is small, the difference of thermal properties between land and sea is not significant, and the phenomenon of tropical monsoon is less than that in tropical monsoon climate zone. ? [ 1]?

There is much convective rainfall in summer and frequent tropical cyclones in summer and autumn; Located on the windward slope of the trade wind zone, there is still some precipitation (topographic precipitation) in the coldest season. Tropical maritime climate and tropical dry and wet season climate are often bounded by mountains, with windward slopes of mountains as tropical maritime climate and leeward slopes as tropical dry and wet season climate.
