Abstract:
There are 22 reference stations and 31 correction stations determined in 76 meteorological stations in Hubei Province. Based on onedimensional regression method, the monthly mean winter temperature correction series in correction stations from 1961 to 2013 are built. The correction series are compared and analyzed in the statistical method and in correction errors, and the results are applied to winter climate impact assessment. The results indicate that the impact of the revised results of stations is significantly greater than those of the divisional and provincial adjustments; the results of divisional and provincial adjustments are basically consistent before and after adjusting, and there is an increasing trend in the number of inconsistency in winter types in provincial adjustment; the changes in winter for typical stations are significant, and there is a transition from cold winter to warm winter, and the reducing of cold winter becomes weakened, and the increasing of warm winter becomes strong.
