Is there a big difference between Mianyang climate and Meishan climate?

Mianyang and Meishan are both in Sichuan basin, and their climate is similar. But there are also the following differences:

The sea-land monsoon alternates in Meishan, which is controlled by the subtropical high in the western Pacific in summer, influenced by the cold air in the northwest and Mongolia in winter, and the annual variation of solar radiation, forming a variety of climate types in this area. Due to the influence of topography and landforms, the annual average temperature is high in the east and low in the west. The annual average temperature in Renshou 17.4℃ is the highest in the city. The annual average temperature in Shan Ling is 16.6℃, which is the lowest in the city. The hottest months are July and August, with an average temperature of 25.4-26.3℃, an extreme maximum temperature of 38.6℃ and an average temperature of 6.2-0 in Leng Yue. The annual frost-free period is 302-3 14 days. Abundant rainfall, uneven distribution of rainfall in time and space. Rainfall increases with different regions from northeast to southwest, with an average annual rainfall of 983- 1490 mm, the minimum annual rainfall of Pengshan is 983mm, and the maximum rainfall of Hongya is 1490 mm. The rainfall is concentrated from May to September, accounting for about 85% of the total annual rainfall (July 28 1996, The maximum rainfall in Hongya is 4 10.8 mm), which is an important reason. The annual sunshine hours are 1060- 1202 hours, which is 24-28% of the available sunshine hours, less than that in the same latitude area, and it belongs to one of the low sunshine areas in China. With the increase of altitude, a complete climate zone from subtropical zone to warm temperate zone to cold temperate zone to sub-cold zone has been formed in Nanshan District of Meishan. The vertical difference of climate (stereoscopic climate) is obvious. The temperature decreases with the elevation, and the temperature decreases by 0.66℃ for every increase of 100 m. Rainfall increases with altitude; It has the climate concept of higher altitude, lower temperature and more rainfall.

Mianyang city belongs to the humid monsoon climate zone in the northern subtropical mountainous area. Mianyang annual average temperature 14.7 ~ 17.3℃. Pingwu County is the lowest, with 14.7℃. The annual average temperature in Mianyang has little interannual change, and the difference between the highest year and the lowest year is only about 65438 0.5℃. The extreme maximum temperature in Mianyang is 36. 1 ~ 39.5℃, and the extreme minimum temperature is -4.5 ~-7.3℃. Mianyang is rich in precipitation, which varies greatly from year to year. The average annual precipitation in Mianyang is 825.8 ~ 14 17mm. Its distribution characteristics are: less in the north and south, more in the middle; There are few in the East and many in the West. Generally the wind speed is small. Only when there is a large-scale invasion of cold air in the north in winter and spring or there is a thunderstorm in summer will there be windy weather. The northeast wind to the north wind prevails in this city. The annual average foggy days in this city are 3.3 ~ 6 1.0 days. Mianyang City is the highest and Pingwu County is the least.
