Do you know how much is the temperature of the water?

Every year a lot of people like to go on holiday to southeast Asia, the reason is that southeast Asia has a lot of clear, sand beach, swimming in the sea can fall, heat and can exercise the body. Do you know how much is the temperature of the water? The water temperature is reflect the status of seawater hot a physical quantities. Seawater temperature went unquestioned, months, years and years of periodic change and irregular change, it mainly depends on the heat balance of payments and its time to change. The temperature change of the oceans of the world is in commonly - 2℃本; Between 30 ℃, annual average temperature of more than 20 ℃ area accounts for more than half of the entire ocean area. By direct observation showed that the water temperature variation is very small, changes in water depth range from 0 & ndash; 30 meters, the annual change can be reached 350 meters water depth. In the depth of 350 meters, there is a constant temperature layers. But along with the depth increasing, the water temperature gradually decreases, For every 1000 meters deep, about 1 & deg; — 2℃） In the depth of 3000 & ndash; 4000 meters, the temperature reach 2 & deg; — - 1℃。 The water temperature is one of the most important factor in Marine hydrology, often used as a research nature water body, describe the basic index of the water mass movement. Seawater temperature distribution of space and time and the study, sailing, fishing, and underwater acoustic disciplines is also very important. Three years in the surface of the ocean where the average temperature is about 17. 4 ℃, the highest in the Pacific, 19. 1 ℃, followed in the Indian Ocean, up to 17. 0 ℃, the lowest, is 16. 9℃。 Generally decreased with increasing depth, water temperature in the depth of 1000 meters of water temperature is about 4 ~ 5 ℃, 2000 meters for 2 ~ 3 ℃, deeper than the 3000 meters for 1 ~ 2 ℃. 75% of the total volume ocean water, the temperature is between 0 ~ 6 ℃, the average temperature is about 3 global ocean. 5℃。 Seawater temperature and day, month, year, years such as periodic changes and irregular change.
