What are the main differences between the climates in Chongqing and Qingdao?

A Chongqing is located in the subtropical inland area of the northern hemisphere and belongs to the humid monsoon climate type in the middle subtropical zone. There are mountains in the north and southeast, which constitute the marginal mountains of Sichuan Basin. It has formed a climate feature of "hot summer and warm winter, long frost-free period" and is one of the three "stoves" in the Yangtze River.

The climate of Chongqing is characterized by (1) hot summer and warm winter, and a long frost-free period. Leng Yue (65438+1October) has an average temperature of 7.8℃, a frost-free period of 340-350 days, and an active accumulated temperature above 0℃ of 6000-6900℃, which is the longest frost-free period in the same latitude. (2) The precipitation is abundant and unevenly distributed in time and space. Affected by the Qinghai-Tibet high and subtropical high, heavy rains often lead to droughts in July and August for 30-50 days. (3) It is rainy in autumn, foggy in winter and few sunshine hours, so it is called "foggy city". (4) The vertical distribution of climate is obvious. Due to the influence of topography, Chongqing generally has two inversion layers, about 500-600 meters and 800 meters. The precipitation increases with the elevation, and the rain areas vary from place to place.

B, the climate characteristics of Qingdao:

Qingdao is located in the north temperate monsoon region, near the Yellow Sea. It has the characteristics of monsoon climate and marine climate, with high temperature in winter, slow recovery in spring, less heat in summer and slow cooling in autumn. The air is humid, the precipitation is moderate, the rain and heat are in the same season, and the climate is pleasant.

1, temperature

The annual average temperature in Qingdao 12.7℃, the hottest month appeared in August, the monthly average temperature was 25.3℃, and the extreme maximum temperature was 38.9℃, which appeared on July 15, 2002. The most Leng Yue appeared in 65438+ 10 month, with the monthly average temperature of -0.5℃ and the extreme minimum temperature of-16.9℃, appearing in 193 1 year, 1 month.

Step 2 precipitate

The average annual precipitation in Qingdao is 662. 1 mm. The annual maximum precipitation is1272.7 mm (191year), the daily maximum precipitation is 367.9 mm (1August 199719 days), and the annual minimum precipitation is 308.3 mm (. Most of the annual precipitation is concentrated in summer, and the precipitation from June to August is 377.2mm, accounting for about 57% of the annual precipitation. The maximum precipitation in August is 15 1. 1 mm; The maximum daily precipitation is 223.0mm, which occurred on September 4th. 1970. The minimum precipitation in 65438+ 10 is11.3mm.

July-September is the season with the smallest wind speed in Qingdao. Qingdao is surrounded by the sea, and the characteristics of land and sea breeze are obvious.
