What places are the Beibu Gulf mentioned in the weather forecast?

English name: Beibu Gulf

Introduction: China's Leizhou Peninsula, Hainan Island, Guangxi Zhuang Autonomous Region and the bay between Vietnam are all on the continental shelf. The continental shelf is about 260 miles wide, and the water depth gradually deepens from the shore to the middle, reaching the deepest point of 80 meters. There are Nanliujiang, Honghe and so on. Because there are not many rivers along the coast, less sediment is brought into the bay. The difference of surface water temperature between winter and summer is 65438 00℃. Fish are mainly warm water species, which is an excellent fishing ground for catching red snapper, golden thread fish, blue herring and other fish. The main ports are Beihai City, China, coastal waters and coastal defense.

Location: Located in the northwest of the South China Sea, it is a semi-closed big bay. It borders Leizhou Peninsula and Hainan Island in China in the east, Guangxi Zhuang Autonomous Region in China in the north, Viet Nam in the west and the South China Sea in the south.

Climate type: Beibu Gulf is located in tropical and subtropical zone. In winter, it is affected by the cold air from the mainland, with northerly winds and sea surface temperature of about 20℃. In summer, the wind comes from the tropical ocean, the sea surface temperature is as high as 30℃, and it is often hit by typhoons. Generally, there are about five typhoons passing through here every year.

Geological landform: Beibu Gulf is surrounded by the sea on three sides, and the water depth is 10 ~ 60m. The seabed is relatively simple, gradually descending from the top of the bay to the mouth of the bay. The seabed is relatively flat, and the sediment brought by the land is deposited on it. It belongs to a Cenozoic large-scale sedimentary basin with a thickness of several thousand meters and rich oil and gas resources.

Coastal rivers: the Nanliujiang River and the Red River flow into it.

Water temperature of ocean current: In winter, the Beibu Gulf ocean current rotates counterclockwise, the water in the open sea goes north along the east side of the bay, and the water in the bay goes south along the west side of the bay, forming a circulation; In summer, driven by the southwest monsoon, the current forms a circulation in the opposite direction. There is only one tidal fluctuation here 1 day, which is called the diurnal tide. The fluctuating tidal range gradually increases from the mouth of the bay to the top of the bay, and the maximum tidal range in the waters near the North Sea can reach 7 meters. Tidal currents generally flow along the coast, one after another, which is called reciprocating flow. The annual average water temperature is as high as 24.5℃.

Natural resources: Beibu Gulf is rich in resources. Because of the rich bait, there are more than 50 kinds of fish with economic value here, such as snapper, golden thread fish, sardines, mackerel, blue plaice, tuna, flounder, pomfret, mackerel, shrimp, crab and shellfish. This is one of the best fishing grounds in China. The coastal shallow sea is a vast beach, which is an excellent place to develop mariculture. Shellfish include oyster, pearl oyster, sun-moon oyster, mud clam and so on. The world-famous Hepu Pearl (also known as Nanzhu) is produced here. Weizhou Island, Yinggehai and other seabed oil and gas resources are also considerable. There are many mangroves in coastal estuaries.

Important data: The area is close to 6.5438+0.3 million square kilometers, slightly larger than Bohai Sea. The average water depth is 42m, with the deepest point100m.

Strategic location: Beibu Gulf is the nearest sea passage in the southwest of China. Important ports include Beihai, Fangchenggang, Qinzhou and Yangpu.
