What's the climate like in Japan?

Japan is dominated by temperate and subtropical monsoon climate, with hot and rainy summer, cold and dry winter and distinct four seasons. The national latitude is 25, and the temperature difference between north and south is very significant.

Most areas belong to temperate climate with four distinct seasons. Okinawa in the south belongs to the subtropical zone, and Hokkaido in the north belongs to the sub-frigid zone.

The precipitation in Japan is the highest in the world. The main reasons include winter snowfall in Japan's coastal areas; Continuous plum rains in June-July (May-June in Okinawa and Amami); And typhoons that landed in or near Japan from summer to autumn.

The highest recorded temperature in Japan is 40.9℃, which was measured on August 16, 2007 in Kumagu City, saitama and Dongdao City, Gifu County. The lowest recorded temperature is -4 1℃,1measured in Asahikawa, Hokkaido on October 25th, and it is 1902 65438+.

Extended data:

I. Topography

Japan is a mountainous island country. Mountains are distributed in the center of Japan in the form of ridges, which divide Japan's territory into one side of the Pacific Ocean and one side of the Sea of Japan. Mountains and hills account for 765,438+0% of the total area, and most of them are volcanoes.

The forest coverage rate is as high as 67%. Mount Fuji is the highest mountain in Japan, with an altitude of 3776 meters. It is the highest peak in Japan and is honored as "Shengyue" by the Japanese.

The Japanese archipelago is located at the junction of the Asia-Europe plate and the Pacific plate, that is, the volcanic seismic belt around the Pacific Ocean. Volcanic and seismic activities are frequent, and the more harmful earthquakes will occur 1 time on average within three years.

The plains of Japan are mainly distributed in the coastal areas of the lower reaches of rivers, mostly alluvial plains, with a small scale. The larger plains are Shikai Plain, Yuehou Plain, Houwei Plain and Shi Sheng Plain, the largest of which is Kanto Plain. Japan's plain area is small, the cultivated land is very limited, and the population physiological density is as high as 2924 people/square kilometer, ranking 26th in the world.

Japan is located at the extinction boundary between the Asia-Europe plate and the Pacific plate, and it is a part of the combination of island arc, coastal mountains and trenches in the western Pacific. 68% of this country is mountainous.

Japan is located in the volcanic seismic belt around the Pacific Ocean. One tenth of the world's volcanoes are located in Japan, and volcanic activities often occur all over the country. According to statistics, more than 20% of all earthquakes of magnitude 6 or above in the world occurred in Japan.

Second, the distribution of water system

Japan has short rivers and abundant water resources, and the longest Shinano River is about 367 kilometers long. The largest lake is Lake Biwa, with an area of 672.8 square kilometers.

Japan's coastline is 33,889 kilometers long. As Japan is an island country, its coastline is very complicated. There are many cliffs in the Sea of Japan in the west, few ports, and many estuaries in the Pacific Ocean in the east, forming many natural ports.

In the East Pacific Ocean, it is surrounded by the Japanese warm current (Kuroshio) from south to north, and the Kuroshio cold current (pro-tide) forms in the northeast. In the West Sea of Japan, there are warm currents and Riemann cold currents flowing to Malaysia. At the intersection of cold current and warm current, there are abundant fish resources and become natural fishing grounds.

Because it is surrounded by the sea, it is mild and humid all year round, with no severe cold in winter and no heat in summer. There are many typhoons in summer and autumn, and it rains in June. 1 Monthly average temperature is -6℃ in the north and16℃ in the south; In July, it was 17℃ in the north and 28℃ in the south. The annual precipitation is 700 mm to 3,500 mm, and the highest can reach more than 4,000 mm.
