1, located in subtropical sea area, controlled by subtropical high, with strong evaporation, less precipitation and high salinity.
2. Surrounded by a tropical desert climate zone, there are basically no rivers injected.
3. The sea area is closed. In the south, only the Mande Strait is connected with the Gulf of Aden, and in the north, only the Suez Canal is connected with the Mediterranean Sea, making it difficult for fresh water from outside to enter. ?
The average salinity of the world oceans is 35%. The Red Sea is located between the Arabian Peninsula in Asia and the African continent, with a salinity of 465,438+0-42% in the north. About 37% in the south. 270% have been measured at individual locations on the deep seabed. Above, almost reaching the concentration of saturated solution, it is the highest salinity ocean in the world.
The Red Sea Basin is a part of the Asian-African Rift Valley, which is about 265,438+000 kilometers long. The average depth of the whole Red Sea is 558m, and the maximum depth is 25 14m. The Red Sea is sandwiched between the east and the west by tropical deserts. The air is hot and dusty all the year round, and there are few sunny days. There is little precipitation, but the evaporation is very large, the salinity is 4 1%, and the surface water temperature exceeds 30℃ in summer, which is the highest water temperature and salt content in the world. The average surface water temperature in August is 27℃ to 32℃. The sea water is mostly blue-green, and some areas are reddish brown because of the lush red algae, hence the name of the Red Sea. The annual evaporation is 2000 mm, far exceeding the precipitation, and rivers on both sides of the strait are injected in unpredictable years. The Red Sea is controlled by subtropical high and trade winds, forming a tropical desert climate with large evaporation, scarce precipitation and high temperature all year round. The climate of the Red Sea consists of two monsoon seasons, the northeast monsoon and the southwest monsoon. Monsoon is caused by the temperature difference between land and sea. The Red Sea is one of the hottest and highest salinity oceans in the world. In summer, the average surface temperature is 26℃ in the north and 30℃ in the south, and the total average temperature is 22℃. The rainfall in the Red Sea and its surrounding areas is very low, only 0.03m per year. Generally speaking, it rains in the form of thunderstorms and sandstorms. Low rainfall and lack of fresh water injection lead to a net evaporation of 205 cm per year and high salinity.
