摘要
对2005年浙江丽水两场大雪过程的环流形势和物理量场作了对比诊断分析,分析结果表明:在两次大雪过程中,低空急流、动力、水汽条件表现出较为一致的共性;而大气环流调整,冷空气影响方式,逆温层和地面低温条件表现出较大差异。
Based on the comparison and analysis of the circulation and physical quantities of the two heavy snow events in 2005, it is found that the low-level jet, dynamics and moisture conditions have the coincident effects on the two processes; but the changes of the general circulation, the function of cold air, the inversion layer and low temperature of surface made the different roles in two cases respectively.
