Emei Climate Mount Emei is located in subtropical monsoon climate region, its climate being subject to radiation, atmospheric circulation constraints, the topography plays a very important role. Mount Emei in the "Emei Plain" suddenly the southwest end of the stand, seat west to east, north-south direction, west, twenty to thirty-degree slope and western mountains of buffer bordering the eastern side of the intake body for the steep cliff face of the Sanjiang Plain, Golden Summit , terra-top, the three main peak elevation of 3 Wanfo Ding Qian Yumi, Emei City Shiqianliubai meters higher than at the southwest corner to form a tall city natural barrier, preventing the sea warm and humid air currents drive straight, combined with terrain conditions and the geographical environment on the occurrence and development of precipitation systems and movement, creating a cloud over the entire mountain, the Rizhao less rainfall characteristics of the gas, with the west and other regions constitute a small Liangshan famous Quartet's "West rain screen." While the distribution of climate factors are significant differences emerged in Yicheng to form a "mountain has four seasons, different days, ten-mile", with a cold from the sub-tropical to sub-bands of the climate system as a whole. And thus also the formation of a multiple-attraction, Mount Emei and change the characteristics of - the venue and Jing Shu, Yunfu mountain moving the walls.
Emei obvious vertical distribution of climate, elevation 1,500 meters under the sub-tropical climate; altitude of 1,500 meters ~ 2100 meters is a warm temperate climate; altitude of 2100 meters ~ 2500 meters is in the temperate climate; an altitude of 2,500 meters above belong to sub-arctic climate. Peak and Pingba, a larger temperature difference between the foothills, about a difference of 14 ? for every rise in elevation of 100 meters, the temperature dropped from 0.5 to 0.6 degrees.
Emei City coldest in January, monthly mean temperature of 4.3 degrees, the minimum temperature of minus 4 degrees. Top Mount Emei monthly average temperature from November to March next year are below zero, the coldest month in January, in order to minus 6 degrees, the lowest temperature of minus 20 degrees.
The average July temperature of 11.8 degrees, the maximum temperature of 20 degrees. Emei Mountain region for more than 2,000 m above sea level of about half a year for the snow-covered, usually in October to next April, are the snow-capped Mount Emei, there is no four seasons, only winter and spring of difference, just as our predecessors wrote Cao Song : "May Emei similar to the fire, just like veneer Ridge in winter."
Mount Emei's snow is quite distinctive, both "scenery of the North", another "southern scenery" - trees Qionghua, crystal clear. | Leshan Climate Leshan, Sichuan Basin, southwest mountainous area in the transition zone, topography was Southwest, Northeast High, height difference disparities, in a particular geographical environment, climatic conditions, the formation of a variety of types. From region to region in the vicinity of latitude 29 degrees, the city is in the subtropical climate zone, with four distinct seasons and the characteristics of abundant rainfall, water, heat in the same quarter, a long frost-free period, agro-climatic condition is superior. The annual average temperature at 16.5-18.0 degrees, greater than or equal to 0 ?accumulated temperature of 6100-6500 ? greater than or equal to 10 ?accumulated temperature 5269-5662 ? greater than or equal to 20 ?accumulated temperature of 2930-3376 ? annual average frost-free period as long as 300 days or more, the annual average frost date 4.2-9.4 days, the annual average number of days of snowfall is only 1.0-2.7 days is rice, wheat, oilseeds, sugar, fruit, cotton and other agricultural products of high yield area. Southwest mountain climate vertical differences are significant, from the foothills in turn distributed to the hilltops in a warm subtropical temperate zones 1 a complete cold temperate climatic zone, micro-climatic conditions are very complicated, it is to operate within an integrated development of agriculture and three-dimensional agricultural region is a timber, tea and Chinese medicinal herbs and other major producing regions, is also a valuable tourism resources.
Influenced by the monsoon and the uplift of the role of topography, climate and humid, rainfall abundant. Average annual precipitation is 1,000 mm or more in most areas, Emeishan City, 1,500 mm or more, only ebian, Jinkouhe less than 1000 mm below the seasonal changes in precipitation in summer and autumn rainfall accounted for about 80% of the whole year, winter and spring, only 20% of the difference in a larger inter-annual precipitation, annual precipitation is at least more than 900 millimeters in some areas annual precipitation is 2,000 mm or more up.
The city's meteorological disasters to low temperatures, drought, floods dominated. Low temperature in spring, the greatest impact hazard, can cause cold wheat flower, rice bad kinds of Lan Yang; drought to Chunzao, the main summer drought, severe drought, when part of the local drinking water problems have occurred; affected by topography, Leshan is the rain Multi-prone areas, rainfall intensity, big, Emeishan City, 93 September 29 up to 525 millimeters of precipitation, creating the province the most, plus another at the confluence of three rivers, floods greater impact |
