摘要
采用1957—2015年气象资料,对山西省春季降水、温度及降水温度变化趋势比的时空分布及变化趋势进行了研究。结果表明,山西省春季降水变化趋势存在空间上的差异,其中晋南主要表现为减少趋势,晋西北和晋中部分地区表现为增多趋势,并且这种趋势会随着气候变暖逐渐加强。全省范围内的温度变化均表现为升高的趋势,其中温度升高幅度最大的2个区域分别为五台山地区和晋南的临汾、运城、晋城;晋西北的朔州、忻州、吕梁一带与晋中的太原及其他部分地区温度升幅相对较小。能够反映春季气候变化异常的降水温度变化趋势比的时空分布与降水的时空分布基本一致,仍为五台山地区和晋南最小,晋西北最大,说明未来山西地区气候变化将会变得更加不稳定。
Based on the meteologieal data from 1957 to 2015, the trend and temporal-spatial distribution of the precipitation and temperature change in springs of Shanxi Province were analyzed. The results showed that the spring precipitation trends of Shanxi Province were significant spatial differences. The trends in south of Shanxi Province were declining as well as the trend of northwest in Shanxi Province and parts of cen- ter in Shanxi Province were increasing, and this trend would gradually be strengthened as the climate were getting warm. The tendency of tem- perature were manifested as increasing in province-wide range. The temperature were increasing significantly in the two regions： Wutai Moun- tain area and Lin^en, Yuncheng as well as Jincheng in southern Shanxi. The temperature of Shuozhou, Xinzhou and Luliang in northwest Shanxi as well as Taiyuan and parts of Jinzhong rised relatively small. The temporal and spatial distribution of abnormal precipitation and tem- perature in spring was almost same with the temporal-spatial distribution of the precipitation： the Wutai Mountain area and southern Shanxi minimum, northwest in Shanxi maximum. This showed that the future climate change in Shanxi would become more unpredictable.
