What is the climate in Japan and its distribution areas?

Hello, I found a good introduction to the climate of Japan on the Internet for your reference. I also managed to find a climate distribution map of Japan on the website. Really hope it can be of help to you.

From the specific conditions of different seasons and different regions, there are three main characteristics of Japan's climate. ?

One? Four distinct seasons with large seasonal differences?

Spring in Japan generally starts around February 10 and ends in mid-May. The weather in spring is changeable and there is less rain. Summer lasts for three months: June, July and August. Due to the high temperature and humidity controlled by the subtropical high pressure in the Pacific, Japan is affected by the hot and humid southeast monsoon. The area south of Honshu has a long period of sultry weather, and the precipitation on the Pacific side, that is, "surface Japan" is relatively large. An important characteristic of Japanese summer is that the rainy season begins soon after summer begins and lasts for a long time. September, October and November are autumn in Japan. The weather in autumn is fine, and there is a saying that "autumn is high and horses are fat". From early September to early October, Japan still has the autumn frost season. During this period, typhoons are more frequent and are often accompanied by heavy rains, causing damage. Winter in Japan generally lasts from November 20 to February 20 of the following year. Affected by the cold northwest monsoon from the Asian continent and the Tsushima Current on the coast of the Sea of ​​Japan, the side of the Sea of ​​Japan, known as "Ura Nippon", has heavy snowfall and cloudy weather. There are many days, short days, and humid air, while "Exterior Japan" has less rain and snow, sunny, and dry weather. In winter, the temperature difference between the north and south of Japan is quite large. For example, the average temperature in January is -7.8℃ in Asahikawa, Hokkaido, and 17.2℃ in Naha, Okinawa Prefecture, a difference of 25℃. Due to the rainy season and autumn frost period, Japan also has six seasons a year. ?

II? Significant regional differences?

Because Japan spans the subtropical, temperate and sub-arctic zones, coupled with complex terrain, and is greatly affected by monsoons and ocean currents, the climate in various places is significantly different. . From south to north, it can be roughly divided into three major climate zones: the western and southwestern coasts (generally areas south of 35° north latitude) have a monsoon subtropical forest climate; the north (Hokkaido and northern Honshu) has a monsoon temperate coniferous forest climate; the rest Most areas have a monsoon temperate broad-leaved forest climate. In addition, based on the four indicators of temperature, precipitation, sunshine rate and excess moisture (wet and dry climate), Japanese scholars have further subdivided Japan's climate zones into the following six types:?

(1) "Ura-Japan" type?

Winter monsoon precipitation (snow), with many cloudy days and short sunshine hours in winter, is the main snow-covered area in Japan. ?

(2) Kyushu type?

The temperature is high, the sunshine time is long, there is little rain in winter, and the rainfall is mainly concentrated in summer. ?

(3) South China Sea type?

Affected by the Kuroshio, the temperature is higher. During the plum rains in June and typhoons in September, the rainfall is concentrated, the sunshine is long, and the humidity is high. ?

(4) Setouchi type?

The climate is warm, sunny, with less rainfall and low humidity. There is less rain in winter and more rain in summer. ?

(5) "Express Japan" type?

The sunshine time is long and the precipitation is high in winter. ?

(6) Okinawa type?

High temperature, no frost, no snow, many typhoons and rain. ?

Three? Warm and rainy?

Japan has a mild climate, and the annual average temperature is mostly above 10℃. Only some areas in Hokkaido, northern Tohoku, and Honshu mountainous areas have an average annual temperature above 10℃. the following. There is no severe cold in winter, and the average temperature in northern Hokkaido in January is no less than -10°C; there is no extreme heat in summer, and the average temperature in August in the southern region is between 25 and 26°C; the annual average temperature in Tokyo, located in the center, is 15.3°C. ?

Japan has abundant rainfall, with an average annual precipitation of about 1,800 mm, which is much higher than that of countries on the east and west coast of Eurasia. For example, the annual rainfall in Akita is three times that of Beijing at the same latitude. Tokyo's annual rainfall is more than twice that of London and Mali. The areas with the most precipitation in Japan are southeastern Kyushu, southern Shikoku, southeastern Kii Peninsula, and the central prefectures of Fukui, Ishikawa, and Gifu, with annual precipitation exceeding 3,000 mm. The Seto Inland Sea coast, the Pacific coast of the northern Tohoku region, and the eastern half of Hokkaido have annual precipitation of less than 1,200 mm. The amount of precipitation in Japan changes significantly depending on the season. There are generally three types:?

(1) "Uri-Japan" type?

Winter monsoon precipitation (snow), and December or January is the most popular. ?

(2) Southwest Japan type?

Meiyu precipitation is the most in June or July. ?

(3) Northeast Japan type?

Typhoon precipitation is the highest in September.
