What kind of climate does cold current and warm current bring?

The climate brought by the cold current is low temperature and little rain. The cold current invading China originated in the Arctic Ocean. Because the sunshine time in this area is short, the night is long, and the four seasons are like winter, in such a cold climate, the air volume is constantly shrinking into a powerful cold airflow, which is the cold current. Then, a cold current hits this warm place in China, and the temperature can drop by more than 10℃ in one day and night. The climate brought by the warm current is the huge heat energy contained in the ocean with high temperature, rainy and warm current and its influence on the climate, which has aroused widespread concern of scientists from all over the world, among which the most important ones are the Gulf Stream and Kuroshio. The Gulf Stream contains a huge amount of heat, which is probably more than that generated by burning coal all over the world in one year. Because of its arrival, every 1 meter of land on both sides of the English Channel enjoys the warmth of burning 60 thousand tons of coal every year. If we compare the east coast of Canada at the same latitude, the discrimination is even more obvious: the average annual temperature in eastern Canada on the other side of the Atlantic can be as low as-10℃, while it can be as high as 10℃ in northwest Europe at the same latitude.
