Quantification of Precipitation Variation with Wavelet Analysis of Departure from Average and Cumulative Departure from Average in Major Grain Producing Area, Henan Province, China

Jianhua Ping and Furong Yu

Abstract:
Precipitation fluctuation research is essential to water security and grain production security. The monthly, annual and growing seasonal precipitation departure from average and cumulative precipitation departure from average were analyzed quantitatively via wavelet analysis to assess the characteristics of precipitation in multi-scales. The results indicated that precipitation changes and varies at three scales which are 4, 8 and 17 years. Wavelet analysis provides a special approach to evaluate the departure from average and cumulative departure form average.
