摘 要:根据山东省霜冻气候概况,把全省分成6个预报区,每个区选取有代表性的测站,应用探空、地面观测资料和逐步回归方法,建立测站的日最低气温和日最低地温的短期预报方程;把HLAFS数值预报资料代替高空资料代入预报方程,进行最低气温和地温的预报;根据霜冻与气温和地温的关系及分区预报霜冻的标准,判别预报区内有无霜冻。Shandong province was divided into six forecast regions,based on the frost climate in the province representative stations were selected in each region,and the short range forecast equation of daily minimum air and soil temperatures was established for each selected station by the use of sounding,surface observation and stepwise regression method.The forecast equation introduces HLAFS numerical forecast data instead of sounding and gives the forecast results of minimum air and soil temperature.According to the relationship between frost and air and soil temperature and the sectorized forecast indexes for frost,a determination whether it is frost or not in the forecast region was given.The operational system of the short range forecast for frost in Shandong province was developed.
