摘要
利用广西1960～2000年冬季冻害站次资料,根据规定的指标,划分出广西冬季严重冻害年有12年,将12个严重冻害年的500hPa高度场进行合成,分析了广西冬季严重冻害当年和前一年的500hPa高度合成距平场特征以及前期主要影响月的500hPa高度合成距平场的主要特点,为广西冬季严重冻害的预测提供判别依据。
12 years are identified as having serious winter freeze injury, according to specific indices and information from winter freeze injury stations during the period of 1960 ~ 2000. The 500hpa altitude fields in the 12 years are synthesized with a view to analyze the characteristics of the 500hpa altitude synthetic anomaly field of the year involved and the year before, and the main features of the 500hpa altitude synthetic anomaly field of in the early stage of the influenced month, providing a judging basis for the forecast of serious winter freeze injury in Guangxi.
