What are the five permanent members?

Wuchang is a county-level city under the jurisdiction of Heilongjiang Province, which is managed by Harbin. Located in the south of Heilongjiang Province, on the upper reaches of Lalin River, bordering Acheng District of Harbin in the north, shangzhi city, hailin city and Dunhua in Jilin Province in the east and southeast, shulan city and yushu city in Jilin Province in the south and southwest, and Shuangcheng in the northwest.

Wuchang city is bordered by Zhangguangcailing in the east, Songnen Plain in the west and north, with high terrain in the southeast, mountainous and forested, and hilly and gully in the middle. The northwest lies in the plain. Dadingzi Mountain is 1696 meters above sea level, which is the highest peak in Heilongjiang Province. The Lalin River flows from southeast to northwest, obliquely crossing the territory. There are Longfengshan Reservoir and Mopanshan Reservoir.

The topography of wuchang city is a transitional zone from mountainous areas to plains. Therefore, the geomorphic outline is strictly controlled by the structure, and the geomorphic units are in transitional distribution. Another main feature of geomorphology is that the geomorphic units caused by internal and external forces are very obvious.

Zhongshan landform is produced by the uplift of crustal movement, and hilly landform is the result of external erosion. Various landforms in China clearly reflect the interaction of internal and external forces in the process of landform generation, development and evolution.

Climatic characteristics of wuchang city;

1. Winter is long, cold, dry and little snow: Winter (11-March) lasts for five months, which is often controlled by northwest airflow and Mongolia cold high pressure, resulting in cold, dry and little snow. Once a snowstorm is formed, it will often cause a sudden drop in temperature, accompanied by strong winds, which will affect road traffic and outdoor activities of residents.

2. Summer is short and hot, and rainfall is concentrated: summer (June-August) lasts only about 3 months. Under the influence of subtropical ocean air mass, the temperature is high and rainfall is concentrated, which often shows obvious characteristics of rain and heat in the same season, which is easy to cause floods.

3. The temperature in spring is changeable and the wind is dry: in spring (April-May), the force of warm air in the north is enhanced, and the temperature rises rapidly. Due to frequent cyclone activities, the temperature often changes. When there is a strong cyclone crossing the border, sandstorm weather is formed, and the air is dry, which is prone to spring drought.

4. The temperature is low and cool in autumn, and the first frost is early: in autumn (September-10), the cold air force in the north is strengthened, and the temperature drops suddenly. Due to the large-scale invasion of cold air, the first frost is prone to occur.
