摘  要：
[目的]研究2010年辽宁省春季低温对农业的影响及成因。[方法]应用天气学分析原理,通过对大气环流形势及卫星云图的分析,探讨2010年4～5月辽宁省春季低温对农业的影响及此次低温天气产生的成因。[结果]高空形势分析表明,2010年4月欧亚大陆高纬度为两槽两脊的形势,乌拉尔山高压脊加强东移,贝加尔湖冷空气沿脊前东南下,并加强成冷涡;辽宁位于冷涡的前锋,受冷涡影响,辽宁地区气温偏低;2010年5月上旬冷空气活动频繁,有2次冷涡影响,气温仍处于低位;中旬后期有暖脊挺进,气温回升。高空槽是产生降水的主要系统,低空急流是降水产生的动力条件;冷涡是此次春季持续低温产生的主要原因;降水多是低温天气产生的次要原因。[结论]该研究为辽宁省春季低温的预防预测提供参考依据。

摘  要：
[Objective] The research aimed to study the influence of spring low temperature on the agriculture and the formation reason in Liaoning Province in 2010.[Method] Based on the synoptics analysis principle,by analyzing the atmospheric circulation situation and satellite cloud map,the influence of spring low temperature on the agriculture and the formation reason of low temperature weather in Liaoning Province during April-May,2010 were discussed.[Result] The high-altitude situation analysis showed that it was two-trough-two-ridge situation in the high latitude of Eurasia in April,2010.Ural Mountain high-pressure ridge strengthened to move eastward.Lake Baikal cold air went down toward the southeast along the ridge front and strengthened into the cold vortex.Liaoning was in the front of cold vortex.Affected by the cold vortex,the temperature in Liaoning area was low.In the first dekad of May,2010,the cold air activity was frequent.There were two times cold vortex influence,and the temperature was still low.In the later period of middle dekad of May,the warm ridge entered,and the temperature rose.The high-altitude trough was the main system of precipitation generation,and the low-level jet stream was the dynamic condition of precipitation generation.The cold vortex was the main reason of spring continuous low temperature generation.The secondary reason was the more precipitation.[Conclusion] The research provided the reference basis for the prevention and prediction of spring low temperature in Liaoning Province.
