Characteristics of temperate monsoon climate

Characteristics of temperate monsoon climate;

1. Summer is hot and rainy. In summer, the solar altitude angle increases, the days are long and the temperature is high. The southeast monsoon blowing from the tropical ocean brings abundant precipitation.

2. It is cold and dry in winter, and the average temperature in Leng Yue is below 0℃, which is cold in winter. This is due to the high latitude, low terrain and flat terrain, which weakens the winter wind.

The monsoon is extraordinary. Summer and autumn are often affected by tropical cyclones.

The temperate monsoon climate (mid-latitude monsoon climate) is distributed on the east coast of the mid-latitude continent in the northern hemisphere, with an annual average temperature of not less than 0℃ and an annual accumulated temperature of 3200℃ ~ 4500℃. It is a transitional climate between subtropical zone and temperate zone, with high temperature and rainy summer, cold and dry winter and distinct four seasons.

cause

The cause of formation is similar to subtropical monsoon climate. Winter is controlled by temperate continental air mass, which is cold and dry with large temperature difference between north and south; In summer, it is warm, hot and rainy, and the temperature difference between north and south is small due to the influence of temperate marine air mass or denatured tropical marine air mass. It is cold and rainy in winter and warm and rainy in summer.

In winter, influenced by the strong Siberian continental cold high, winter winds prevail, the wind is strong, the weather is sunny and cold, and there is little rain and snow. The average temperature in Leng Yue varies greatly from north to south, below 0℃ in the south and below -20℃ in the north, and the average latitude decline rate is 2℃/ latitude distance.

In summer, influenced by the Pacific subtropical high, the summer monsoon prevails, mainly southeast wind, with less wind; It is wet and rainy, and the precipitation from June to August accounts for more than 70% of the annual precipitation. The average temperature in the hottest month in the south can reach above 26℃, but it decreases to the north, not lower than 20℃. The average latitude decline rate is only 0.4℃/ latitude distance. Natural vegetation is deciduous broad-leaved forest and mixed coniferous and broad-leaved forest. The cause of formation is mainly influenced by the thermal properties of land and sea.

distribute

Temperate monsoon climate zone, Korean peninsula, northern Japan and southern Russian Far East. It is located in the east temperate zone of Eurasia, specifically in North China, Northeast China of China, Northeast China of Honshu, Hokkaido Island, most parts of the Korean Peninsula and the Russian Far East.

The east coast of Eurasia, south of the sub-frigid zone, north of Qinling-Huaihe River in China, east of the temperate semi-arid and arid zone, including Northeast China and North China, North Korea and Japan in 37 N, and south of the Far East of the former Soviet Union belong to the temperate monsoon climate zone. The northern boundary of this area is the southern boundary of the sub-cold zone, with the annual average temperature of 4℃ isotherm as the boundary; The southern boundary is based on the average temperature of 9.5℃ in eight months of the year, and it is the northern boundary of the subtropical climate zone.

In China, this boundary is roughly equivalent to the Qinling-Huaihe line, and it is also roughly consistent with the zonality. The western boundary of temperate monsoon climate extends along the northeast of Daxing 'anling to the eastern end of Waixing 'anling. Here, the boundaries between sub-frigid coniferous forest climate, temperate monsoon climate and temperate continental arid and semi-arid climate are relatively close. The land and sea distribution and topographic structure of East Asia have a great influence on the range of temperate monsoon climate, such as the northeast-southwest mountainous areas, which can prevent the deepening of monsoon forces.
