Suining belongs to the subtropical humid monsoon climate in Sichuan Basin. The climate is mild, the rainfall is abundant, the four seasons are distinct, and the monsoon climate is remarkable. Warm winter and dry spring, long frost-free period. Summer is hot, rain and heat are the same season, and drought and flood alternate. It is rainy in autumn, foggy in winter, less sunshine and high humidity.

The temperature rises and changes obviously. The average temperature in winter in 65438+ 10 is 6.0~6.5℃, but the daily average temperature and extreme minimum temperature in winter rarely drop below 0℃, so there are few serious snow and ice weather. The temperature rises rapidly in spring, usually from the end of February to the beginning of March. Summer is very long, and it is often sunny and hot in midsummer. The temperature in autumn is more suitable.

Rainfall is abundant, unevenly distributed, with large annual and seasonal changes, and droughts and floods are often staggered. The annual rainfall is about 950 mm, April ~ 10 is the rainy season, and it often rains at night in late spring and early summer, so it is called "night rain". In midsummer (July-August), rainfall is concentrated, alternating with drought and flood, accounting for 35% of the whole year, and there are often heavy rains and floods. It often rains in autumn, usually lasting 6 to 7 days.

There are more clouds and less sunshine, especially in autumn and winter. The average annual cloud cover exceeds 80%. High air humidity; The wind is small, the wind speed is low, and the average wind speed is mostly below 2.0 m/s; There are few strong winds above magnitude 8, and there are only 1~2 days of strong winds in Fujiang River Basin all year round. There is less hail and more thunderstorms.

The railways that have been opened to traffic include Dacheng Railway (Chengdu-Suining single track, Suining-Dazhou double track), Suicheng Railway (double track) and suining-chongqing railway (double track). It takes only 1 hour to get to Chengdu and Chongqing by bullet train.

The planned railways include Miansui Neiyi Railway (Intercity Passenger Dedicated Line).

According to the Medium-and Long-Term Railway Network Planning of China issued by the former Ministry of Railways, in order to meet the rapid growth of passenger demand, a rapid passenger transport corridor between provincial capital cities and large and medium-sized cities will be established, and a "four vertical and four horizontal" railway rapid passenger transport corridor and three intercity rapid passenger transport systems will be planned. Suining will be a Nanjing-Wuhan-Chongqing-Chengdu passenger dedicated line, connecting southwest and east China. At the same time, according to the planning principle of passenger and cargo separation, Suining will also be an important passage of Nanjing-Wuhan-Chongqing-Chengdu double-deck container transportation corridor. The plan will improve the layout and new development lines of the western road network, expand the scale of the western road network and form the skeleton of the western railway network. After 20 10, a new Lanzhou-Chongqing line will be built, from Lanzhou to Chongqing via Jiuzhaigou and Mianyang. If we can work hard to extend the Inner (Jiang)-Kunming Railway and build the Suining-Neijiang Railway, it will certainly consolidate Suining's position as a railway hub in Sichuan, make Suining's location advantage more obvious, make its investment environment better and have a better prospect for economic and social development. The expressways that have been opened to traffic include G42 Hu Rong Expressway (Chengdu-Suining-Nanchong-Guang 'an Section), G93 Chengdu-Chongqing Ring Expressway (Suining-Chongqing Section), G93 Chengdu-Chongqing Ring Expressway (Mianyang-Suining Section), Provincial Highway S1Neisui Expressway and Provincial Highway S40 Suimei Suining-Ziyang Section.

The highways that have been planned for bidding construction are: Suijian Expressway (Suining-Jianyang).

"One Ring Road": Expressway meets in Suining to form a ring road, namely Suining Ring Expressway. From Chengnan Expressway (Guihua to Auspicious Section), Suiyu Expressway (Guihua to Fuxing Interchange Section) and Miansui Expressway (Auspicious to Fuxing Section).

Trunk unblocked project. With national highways and provincial highways as the main trunk, the city's "three rings", "three horizontal and four vertical" expressway network will be constructed. "Three Rings" Highway Network: "Inner Ring"16km, using Fujiang Bridge 2, Bridge 3, National Highway 365, 438+08 and Provincial Highway 205 to form a small ring in the city, forming an urban traffic trunk line. "Central" is 2 10 km, forming an inter-county fast circular channel connecting Chuanshan, Anju, Daying, Shehong, Pengxi and Chuanshan counties, and improving the comprehensive service capacity of trunk road network. The "outer ring" is 380 kilometers long, forming an annular channel connecting the towns around the city, improving the radiation capacity of the highway network.

"Three Horizons, Four Horizons" Expressway Network: Rebuild and construct the 280 km "Three Horizons" and 460 km "Four Horizons" expressway network in the city, upgrade the interconnected expressways in the city, and open up the broken roads between Suining and surrounding cities. The mineral deposits with large reserves mainly include oil, natural gas, well salt, placer gold and limestone. , especially natural gas and brine resources.
