“98·7”武汉、黄石特大暴雨过程的小波分析
Wavelet analysis of extreme rain in Wuhan and Huangshi stations in July 1998
【摘要】 通过对 1 998年 7月鄂东特大暴雨期间武汉、黄石两站逐小时地面要素和云顶亮温 (BlackBodyTemperature)资料的小波分析 ,清楚揭示了上述两站降水、气温、气压、相对湿度和云顶亮温等气象要素的时频扰动特征 ,并通过小波逆变换从原资料序列中分离出不同尺度的信息
【Abstract】 The hourly surface elements data and black body temperature of Wuhan and Huangshi stations in the east of Hubei province are analyzed by wavelet transformation. It shows clearly disturbed time frequency characteristics of precipitation, temperature,pressure,relative humid and black body temperature in two stations. Different scale information is separated from raw data by using inverse wavelet transformation.
