利用天气学原理，对普兰店地区2012年春季低温寡照的成因进行分析，得出造成普兰店地区低温寡照的主要天气系统为高空槽。低空急流是水汽输送的通道，地面气旋产生辐合上升，使暖湿气流凝结，产生降水，导致低温寡照。春季3、4月降水多，土壤湿度偏大，农民、农机不能下地，整地备耕工作受阻、农作物播种期明显推迟，植物萌芽、开花期拖后。棚内瓜果、蔬菜生长缓慢，成熟期延长，直接影响菜农的经济效益。

Based on the principle of synoptic meteorology ,the cause of low temperature and overcast weather in spring of 2012 in Pulandian Area was analyzed.It came to the conclusion that upper trough was the main weather system which caused low temperature and overcast weather in Pulandian Area,low-level jet was water vapor transport channel,the cyclone near the surface produced convergence ascending,made warm and wet flow condensation,precipitation,resulting in low temperature and overcast weather. There was more rainfall in March and April ,soil moisture was too large, farmers and farm machinery couldn′t work in the fields,soil preparation work would be hindered,crop sowing date would be significantly delayed,plant germination,flowering period would be lagged.Fruits and vegetables in greenhouse would be grow slowly ,mature period would be extended,which directly influence the economic effect of farmers.
