The contents of the Dover Strait in England

The English-Dover Strait consists of the English Channel (called the Lamanche Strait) and the Dover Strait (called the Dover Strait). Located between the European continent and the island of Great Britain, it is an important sea passage connecting the North Sea and the Atlantic Ocean. The channel is about 600 kilometers long, bounded by the estuary of the Seine River in France and Portsmouth on the south bank of England, with the English Channel in the southwest and the Dover Strait in the northeast. The narrowest part of the strait is only 33km, and the widest part is 180km. It covers an area of about 90,000 square kilometers. These two straits are actually one, but they have been divided into two straits in history.

The island of Great Britain was originally connected with the European continent. Later, influenced by the alpine orogeny, the island of Great Britain was separated from the European continent and became the current strait. The bottom of the river is mainly gravel and rocks. Because the Atlantic Ocean and the North Sea meet here, the English Channel has rough waves, strong winds and dense fog, making it very difficult for ships to sail. The southwest opening of the strait is wide and trumpet-shaped. Tidal energy collected from the Atlantic Ocean is rapidly concentrated, and the powerful tidal current causes huge waves as high as 6 meters, which also forms a huge tidal range. The tidal range between St. Marlowe Bay and the mouth of Songmei River in France can reach 12 meter high. The maximum tidal range at Langsi estuary is as high as13.5m. ..

Influenced by the North Atlantic warm current and westerly wind, the Strait is warm in winter and cool in summer, with wet, rainy and foggy all year round and few sunny days. On the French coast here, there are about 200 rainy days a year, with rainfall exceeding 800 mm; The British coast is blocked by mountains, and the annual rainfall exceeds 150 days. Because the cold air in the north meets the warm ocean, it is foggy all year round, and the foggy season lasts for more than 6 months. The strait is rich in resources, rich in herring, herring and flounder. Mineral resources include oil and natural gas. Ocean tidal energy is about 80 million kilowatts, accounting for about 5% of the total tidal energy in the world. France's Reims tidal power station, built in 1966, with an annual power generation of 544 million kWh, is the largest tidal power station in the world at present.
