On June 5th last year, Wenzhou was awarded the title of "China Climate Livable City" by the National Climate Center. Recently, a set of meteorological data released by the Municipal Meteorological Bureau shows that there is no severe cold in winter in Wenzhou and no intense heat in Ciel Phantomhive, and the annual average temperature is 18.3 C; Wenzhou has few haze days and fresh air, and there has been no severe haze in the past five years. These climatic characteristics make Wenzhou live up to the name of "livable".
The temperature is suitable for warm winter and cool summer.
Wenzhou is a "warm and moist state", with obvious advantages in climate resources and atmospheric environment, with four advantages in climate resources: warm and humid, abundant rainfall, abundant sunshine and distinct seasons.
According to the relevant person in charge of the Municipal Meteorological Bureau, the temperature in Wenzhou is suitable, warm in winter and cool in summer, with no severe cold in winter and intense heat in Ciel Phantomhive. In Wenzhou, spring, summer and autumn are longer and winter is the shortest.
The air is fresh in foggy days.
In the past seven years, the haze weather in Wenzhou City has been effectively controlled. According to the Municipal Meteorological Bureau, the haze days in Wenzhou have dropped from 150 days in 2013 to 29 days in 2018 and 2019. In particular, severe haze has not appeared in the past five years; In recent three years, even moderate haze has not appeared.
With less haze, the air is "fresh". According to the monitoring of negative oxygen ions in the whole province, the content of negative oxygen ions in the air in southern Zhejiang is obviously higher than that in central and northern Zhejiang. In particular, the average negative oxygen ions in alpine forest areas in Taishun and Wencheng areas of our city are as high as 4,000 per cubic centimeter, and the observation value of Wuyanling in Taishun ranks first in the province.
Wenzhou is rich in rainwater resources. The average annual precipitation in Wenzhou City is 1735 mm, ranking first in the prefecture-level cities in the province. The availability of rainwater resources is high, and the average precipitation intensity during extremely short-term heavy precipitation is small. Wenzhou is one of the regions with the richest rainwater resources in China.
Wenzhou is also rich in wind energy resources, and the exploitable amount of offshore wind power technology exceeds 4 million kilowatts. The 70-meter wind energy resources of offshore islands are second only to Zhoushan Island, ranking second in the coastal area of Zhejiang Province, belonging to the third category of wind power development, with great potential for development and utilization of wind energy resources.
High risk of meteorological disasters
According to experts from the Municipal Meteorological Department, although Wenzhou has a suitable climate, it is still in a high disaster risk area in China and even the whole world, and meteorology and its secondary disasters account for more than 90% of natural disaster losses. Influenced by the typical monsoon climate, meteorological disasters in Wenzhou are diverse. Except sandstorm, 14 kinds of meteorological disasters have occurred, such as typhoon, rainstorm, cold wave, fog, low temperature, high temperature, haze, drought, lightning, blizzard, frost, tornado, gale and hail.
There are three main characteristics of meteorological disasters affecting Wenzhou. First, the intensity of landing typhoons is getting stronger, which seriously affects the number of typhoons. Since the establishment of People’s Republic of China (PRC), the number of typhoons landing in Wenzhou has been 0.3 per year, which seriously affects the number of typhoons per year, with the overall trend of more and stronger; Second, the rainfall in the flood season and the number of rainstorm days showed a double increasing trend. The total rainfall in the plum and typhoon seasons accounted for 68.28% of the annual precipitation, and the plum rain in Wenzhou was atypical. The regular date of entering plum blossom was May 27th, and the date of leaving plum blossom was June 25th. Third, strong convection leads to an increasing trend of lightning and short-term heavy precipitation. Strong convective weather such as short-term rainstorm, thunderstorm and gale, hail and lightning in spring and summer has the characteristics of locality, suddenness and strong disaster.
