Abstract: In order to predict the date on which the temperatures above 5℃ stably as accurately as possible in the spring climatic prediction business, based on the daily mean temperature data of 53 observational stations in Liaoning during 1961-2010, and NCEP/NCAR monthly mean reanalysis data, and monthly mean SST data reconstructed by NOAA, the author sought the influential factors of the dates on which the temperatures above 5℃ stably in the spring in Liaoning Province by correlation analysis method and detailed general survey of physical factors. Meanwhile, the author established the prediction equation by multiple linear regression method. Results showed that: the date of the temperature above 5℃ stably in the spring in Liaoning Province appeared earlier and earlier during 1961 to 2010. The influential factors included February North Atlantic SST, January Northwest Pacific SST, February AO, January Indian Ocean SST, October Aleutian low strength and January NAO. The prediction equation had significant meaning.
