Brief introduction of continental climate characteristics in temperate zone

1, temperate continental climate, characterized by warm Leng Xia in winter, large annual and daily temperature difference, sparse precipitation and concentrated in summer, strong sunshine and windy and dusty weather.

2. The temperate continental climate is mainly distributed in Eurasia, the inland area of North America and the southeast of South America at 40 ~ 60 north latitude. China's temperate continental climate is mainly distributed in northwest China, and the average annual precipitation is generally less than 500mm, which belongs to semi-arid or arid areas. Its climate is characterized by hot winter in Leng Xia, large annual temperature difference, concentrated precipitation, distinct four seasons, less annual rainfall and strong continental climate.

3. Temperate continental climate can be divided into broad sense and narrow sense. The generalized temperate continental climate includes temperate desert climate, temperate grassland climate and sub-frigid coniferous forest climate. The narrow concept will exclude the latter. The temperate continental climate is characterized by severe cold in winter and hot in summer, with large annual and daily temperature differences.

4. Winter is controlled by high pressure, and the lowest temperature reaches-73℃; In summer, the average temperature in July in the south reaches 26 ~ 27℃, and the highest temperature is 33℃, which is close to 20℃ in the north. The maximum annual change range is 62.3℃. Controlled by continental air masses throughout the year, precipitation increases from south to north (from west to east in North America), with annual precipitation below 200mm to about 400mm and 300-600 mm in the north. Natural vegetation from south to north, from temperate desert and temperate grassland, transits to coniferous forest in sub-frigid zone.

Because it is far away from the ocean, the humid climate is difficult to reach, so it is dry and rainy, and the climate is very continental. The annual and monthly temperature differences are the highest among all climate types. Moreover, the closer to the center of the mainland, the drier it is, the greater the annual and daily temperature difference, and the transition of vegetation from forest to grassland and desert. The climate features are: Leng Xia is hot in winter, with large annual temperature difference, concentrated precipitation, four distinct seasons, less annual rainfall and strong continental nature.
