Four Seasons Characteristics of the North
Features: It is hot and rainy in summer and cold and dry in winter. Temperate monsoon climate; the temperature is below 0 degrees in winter and the rainiest in summer.
Affected by northerly winds from high latitudes inland, the polar continental air mass prevails here in winter, which is cold and dry
In summer, it is affected by polar ocean air mass or morphed tropical ocean air mass, and Donghe air mass prevails Southeast wind, warm, hot and rainy weather, hot and rainy weather in the same season. The annual precipitation is about 1,000 mm, and about two-thirds of it is concentrated in summer (summer is hot and rainy, winter is cold and dry). Distribution: Appears on the east coast of the Eurasian continent around 35° to 55° north latitude, including the area north of the Qinling Mountains-Huaihe River line in eastern China, the Korean Peninsula, the north of Japan, and the south of the Russian Far East. It is located in the temperate eastern part of Eurasia, specifically in North China, Tohoku, the Northeastern region of Honshu, Japan, Hokkaido Island, most of the Korean Peninsula and the Far East of Russia. Cause: Located between the largest continent and the largest ocean, the thermal properties of land and sea are significantly different. In summer, the Eurasian continental low pressure is connected, and the subtropical high pressure over the ocean extends westward and northward. The southeast monsoon emanating from the North Pacific subtropical high brings abundant precipitation; in winter, the northwest monsoon emanating from the powerful Mongolian high affects the local area. Because the wind shear meets the requirements of monsoon, it is a monsoon climate. Characteristics 1. High temperature and rainy weather in summer: In summer, the sun’s altitude angle increases, the days are longer, and the temperature is higher. The southeast monsoon blowing from the tropical ocean brings abundant precipitation.
2. Winter is cold and dry: the average temperature in the coldest month is below 0 degrees Celsius, and winter is cold. The causes are: the local latitude is relatively high, close to the source of winter winds, and the terrain is low and flat. The terrain is high in the west and low in the east. Winter winds strengthen.
3. The monsoon is significant.
4. Summer and autumn are often affected by tropical cyclones. The natural zone is a temperate deciduous broad-leaved forest zone. Since the climate characteristics of the above temperate climate types are mainly humid (China's North China Plain and Northeast Plains are semi-humid), temperate broad-leaved forest landscapes are more commonly developed (China's North China Plain and Northeast Plains are forest-steppe landscapes). ), but there are some differences. There are more types of broad-leaved trees in East Asia than in Europe, including Quercus mongolica, Quercus liaotungensis, and miscellaneous trees such as Acer, Tilia, and Betula; western Europe often forms pure forests composed of a single tree species, such as beech forests, oak forests, etc.; broadleaf trees in North America The foliage landscape (including south of the Great Lakes, up to the Appalachian Mountains, the Mississippi River Basin, and the Atlantic coastal lowlands) is dominated by American beech and sugar maple. The entire temperate humid broad-leaved forest belt mainly develops colored brown soil and gray brown soil, while the semi-humid forest steppe belt develops cinnamon soil and black soil.
Main disastrous weather conditions for agricultural landscape in the region include wheat, sugar beets, peanuts, cotton, etc. Winter and spring: cold wave (sandstorm, frost, white damage)
Summer: strong convective weather (thunderstorm, strong wind, hail)
