The Analysis of Evolution Characteristic for Maximum Wind Speed in the Hexi Corridor

Abstract:

Through the Merlot wavelet periodic analysis and Mann-Kendall mutation analysis about the maximum wind speed of 14 weather station in Hexi corridor over the past 41 years,the evolution characteristic of the maximum wind speed can be gotten:the Hexi corridor has about 28-29 years main period and 8-12 years secondary period,presenting sinusoidal curve,and the transformation energy cycled from small to big to small to big;After 1980,there were abrupt changes and decline in Anxi,Jiuquan,Zhangye and Wuwei.The Hexi corridor is in the wind speed environment of same climate conditions,and the inter-annual change feature becomes balanced; but in internal local areas,due to the influence of environment, terrain and urban heat island effect,the secondary period is different,presenting abrupt changes and decreasing tendency in 1980s.
