摘　　要：本文对构成淮阴市春季连阴雨的成因、大气环流特征及主要影响系统进行分析和探讨。利用对大气环流特征参量的计算和环流分型及车贝雪夫多项式展开等方法，建立不同时间尺度的预报方法，预测连阴雨的发生时间及长度。In this paper, the causative factors, general clrculation and the principal impacting systems have heen analysed. Using calculating circulation parameters, classifying circulation patterns and spreading polynomials, the methods for forecasting the day and durationof continuous overcast and rainy days have been establised.
