Annual precipitation in Japan

Most of Japan's 370,000 square kilometers of land belongs to temperate zone, surrounded by the sea, which can basically be said to be a temperate maritime climate.

Compared with China and other Eurasian countries, Japanese climate has the following basic characteristics.

(1) The regional differences are obvious.

Because Japan's land spans a long latitude and is arranged in a long and narrow shape from south to north, spanning the sub-frigid zone, temperate zone and subtropical zone, and each big island has many mountains and complex terrain, which is often influenced by monsoon and ocean currents, the climate difference between regions is very obvious. Japanese meteorologists generally divide Japan into the following three climatic zones: the monsoon subtropical forest climatic zone in the west and southwest, the monsoon temperate coniferous forest climatic zone in the north (Hokkaido and northern Honshu) and the monsoon temperate broad-leaved forest climatic zone in the middle. Even on the same Honshu island, there are great differences in climate between "Japan" facing the Pacific Ocean and "Japan" facing the Sea of Japan: there is a lot of precipitation in winter in Japan, and it is cloudy and snowy; It is often sunny in winter in Japan, but there is a lot of precipitation in summer.

(2) The seasonal characteristics are obvious.

Like China, Japan still uses 24 solar terms, and takes beginning of spring, Changchun, beginning of autumn and beginning of winter as the beginning of the four seasons in the calendar. In astronomy, vernal equinox, summer solstice, autumn equinox and winter solstice are regarded as the beginning of four seasons respectively. Japan's spring is characterized by frequent changes in sunny and rainy days, and its summer is characterized by high temperature and rainy days. In autumn, "typhoon" and "late frost" frequently patronize. Heavy snow is a unique landscape in winter in Japan, especially in northern Japan.

(3) Heavy precipitation

The average annual precipitation in Japan is about 65,438+0,800 mm, while the annual precipitation in southeastern Kyushu, southern Shikoku, Ishikawa, Fukui and other counties exceeds 3,000 mm. The average annual precipitation in Europe is only about 560 mm, and that in North America is only about 640 mm. Akita Prefecture is at the same latitude as Beijing, but the precipitation is three times that in Beijing.
