Using the NCEP 1°× 1°reanalysis data and conventional observation data, a weather dynamic diagnosis of the cold wave process occurred on November, 2011 was analyzed. The results showed that there are 3 main features in the. Cold air activities: large range, temperature dropping quickly, long time precipitation; Temperature rising before the outbreak of cold wave is an important indicator; The strong cold air driving southward after trough is advantageous to the outburst of cold wave; We can judge the effect time and intensity of cold air according to the negative vorticity band heading south at 500 hPa.关键词
