Wavelet Analysis of Meteorological Factors in Kerrchin Right Middle Banner during Last 50 Year
Based on annual temperature,precipitation,evaporation data from 1964 to 2010 of two weather stations,the spatial structure,changes and the multi-time scales characteristics of annual temperature,precipitation,evaporation in the past 50 a in the Kerrchin Right middle Banner had been analyzed using complex morlet wavelet analysis in this report.The results show that there are obvious periodic oscillation of 7 a,12 a and 17-18 a for the annual temperature variation.It has prominent periods of 17-18 a,and the abrupt changes were mainly observed in 1987.There are obvious periodic oscillation of 4 a and 9 a for the annual precipitation variation.The annual precipitation abrupt changes were mainly observed in 1982 and 1998.There are obvious periodic oscillation of 8a for the annual evaporation variation.The results also indicate the climate tend to be warm and dry as a whole in Kerrchin Right middle Banner.
