Monthly air temperature change tendency rate\, according to rise significantly in the winter, especially winter minimum temperature rise is most obvious, that is why people feel that in recent years is not too cold in winter. , according to data from shijiazhuang, spring, summer, autumn, winter every 10 years average temperature rose ℃ , ℃ , ℃ and ℃ . 【 original for 】 Temperature fluctuation can present a natural fluctuations, a certain range of temperature fluctuation belongs to the normal climate change. In addition, urbanization also is heating up a factor that cannot be ignored. [shall be of] About how to adapt and mitigate climate warming, the experts called for, should continue to intensify efforts to energy saving and emission reduction. \The current trend of a warming climate could not be stopped or reversed, but can be slow, and we must take action immediately, so as to adapt to and slow climate change.\ The city professional senior engineer car less static meteorological station said. To reduce hours each year Shijiazhuang annual total sunshine time, on the whole, a trend of gradually reduce, reduce per year on average hours, this decrease trend in the 1980 s after the performance more obvious. Data show that sunshine also performance in each season, which reduce the obvious qiu dong season, spring to reduce minimum, autumn reduce hours per year on average, less per year on average hours, winter, spring, summer, reduce hours and hours per year on average. 【 original for 】 Except under the influence of atmospheric circulation, light reduction may be associated with the increasing of the fog, the haze weather. Car less static, points out that this phenomenon is not exclusive to shijiazhuang, at present many big cities across the country have this phenomenon. This may be due to human activity is increasing in recent years, pollution is aggravating, made the aerosol in the air caused by substances such as increased. After 2021, along with the increase of regulation, the our city haze weather, sunshine time fluctuations. \Impact\ Sunshine time of how much is strongly associated with People39。s Daily life. \The most obvious one is the growth of plants, if less sunshine time focused on the plants need sunshine most of time, their growth will be affected, which disturb the ecological balance.\ Experts say. Now, a lot of people buy a house will be light as the main factors to consider. Medical research has confirmed that the winter sunshine, less prone to vitamin D deficiency, back pain, joint pain, respiratory infections and symptoms such as fatigue, walking instability. Interannual fluctuation is larger rainfall slightly decreases For over 50 years of shijiazhuang annual total rainfall of slightly reduce the trend of precipitation interannual fluctuation is large, most of the precipitation in 1996, is mm。 At least 1972, only mm. , according to the analysis of precipitation change with s has distinct phases, 50 ~ 70 s last century for the relatively wet phase, the phase of drought less rain in the 80 s and early 90 s precipitation has increased, since the late 90 s into the relatively less precipitation and stage, and in 1963 and 1996 two obvious peaks in 1972 a lowest value. \Impact\ \Interannual fluctuation is large, make less rainfall year drought more easily, thus a drought frequency has increased.\ Nearly 54 years, shijiazhuang has 14 years of spring and summer drought, 11 with drought in summer drought. In the 90 s and 1970 s was nearly 54 years in shijiazhuang various types of relatively high incidence of drought period. [shall be of] For agricultural drought, experts strongly advocated choose droughtresistant varieties. In the city, in addition to save water,
