Analysis on the Difference of Soil Temperature Variation before and after Precipitation in Gobi Region
西北戈壁区夏季一次降水前后土壤温度变化规律分析

The characteristicof soil temperature near Jinta oasis area is analyzed by using soil heat equation as well as Morlet wavelet transform during June 22 and August 18,2004.It is found that besides diurnal variation,quasi-4 day and quasi-2 week period fluctuationsare significant during this time.Using the running correlation analysis between downward solar radiation intensity and wavelet analysis result of soil temperature,we can get the conclusion that downward solar radiation intensity is positive correlated...
