Interpretation
Japanese warm current is also called "black tide". The best warmth of the Western Pacific Western China. It is adjusted to the northbound of the East Bank of the Philippine Islands. Mainstream along the east bank of Taiwan Island, the west side of the Ryukyu Islands to Northern China, direct to the southeast shore of the Japanese Islands. It is about 100-200 km wide in the eastern side of Taiwan Island, 400 meters deep; the flow rate is 60 per day 60 kilometers per day. The surface temperature in summer is 29 ° C, 20 ° C in winter, and will be reduced to the north. To the north latitude 40o. In the vicinity of the Qiandao cold flow, under the flooding of the West Breeze, it is repeated to become the North Pacific warmth.
distribution
Japanese warm current is also called "black tide". It is the north branch of the Pacific North Equator Warm. It is a ring of the Pacific Warm Stream, which is the world's second largest warm stream, only after the warmth of the Gulf of Mexico. From the East Sea District, Luzon Island originated in the Philippines, flowing through my country, and east to Northern Pacific warmth in the east. For the world famous warmth. It is characterized by: high temperature, high salt, high water, large transparency.
Cause
It has three factors to form: 1. The North Equator is warm and in the mainland. Second, the summer ocean wind blows and the southeast of the southwest wind in the southeast trust. Third, the influence of gentle deviation strength.
Japanese warmstream is formed by the North Tricolian warmstream to deflect from the eastern part of the Philippine Islands. Its mainstream is along the east bank of Taiwan, the west side of the Ryuket Islands, directly to the east bank of the Japanese Islands, meets the cold flow in the north latitude 40 ° in the north latitude, in the Western Breeze, and then folded to the East, become the North Pacific warmth. Japanese warmth is the most powerful warmth in the western part of the North Pacific. It has a width of about 100-200 km in the eastern side of Taiwan Island, with a depth of 200 meters. The maximum flow rate can reach 60-90 kilometers per day. The average flow rate is about 2.2 million cubic meters per second. Since the Japanese warm current comes from the North 2nd, the water temperature and salinity are higher. The water temperature is 29 ° C in summer, 20 ° C in winter, and the two gradually decrease in north; the salinity reaches the maximum value at a maximum of 150-200 meters, and is 34.8-35.
Effects
Japanese warm flow is the mainstry of the entire East China Seahuan, which has a significant impact on the hydrological meteorological conditions of the sea area.
black tide is a Pacific warm flow Rings, for the world's second largest warm stream, only after the Gulf of the Mexico. Since the Philippines, through the eastern sea area of Taiwan, along the northeast of Japan, in the northern part of the northeast, exchanged in the northern Pacific warmth in eastward. The black tide will bring warm sea water from the tropical water to the cold Arctic sea, warm the cold polar water into the temperature of life survival. The black tide is known from its color than other normal seawater, which is due to less impurities contained in the black tide, and after the sun penetrates through the surface of the water, it is less reflected back to the water. The flow rate of the black tide is quite fast. It is like a highway, providing a rapid and convenient path of a rapidly flowing fish, advancement to the north, so the black tide basin can capture a visualty-like fish, and Other large fish classes attracted to these fish.
Black tide is about 100 to 200 cm per second, with a thickness of about 500 to 1000 meters, a width of about 200 kilometers. The sea-water flow rate of 65 million cubic meters per second in the Tide of Japan, Town, Japan, is about 360 times the largest flow of the Amazon River in the world. The average water temperature of the black tide is approximately 24 to 26 degrees Celsius, and the winter is about 18 to 24 degrees Celsius, and the summer can reach 22 to 30 degrees Celsius. The black tide is also more than 7 to 10 degrees Celsius, which is more than 20 degrees Celsius. The mainstream of the black tide is not flowing along the edge of the East Asia, but along the East Asian island arc, therefore, the impact of black tide on the island arc is also significant from the mainland. However, the tributary of the black tide extends into the edge of the East Asian continent, but also has a certain impact on the continental area.
