According to the relationships between frost and temperature, ground temperature, based on local frost forecast standard, the short-term forecast equation was used to judge if frost occurred in Lianyungang City. Via real-time weather mo- nitoring, accurate and fine forecast and early warning, short-term objective forecast business system of frost in Lianyungang was established for a full range of effective service.展开更多

文摘Based on annual minimum air temperature, the minimum ground temperature, cloudiness, air pressure, wind velocity in Lianyungang City during 1971 -2010 and sounding geopotential height, wind direction, dew point and temperature at related stations, using mathematical stepwise regression method and SPSS statistical software, short-term prediction equations of daily minimum air temperature and daily minimum ground temperature at the observation station were established. According to the relationships between frost and temperature, ground temperature, based on local frost forecast standard, the short-term forecast equation was used to judge if frost occurred in Lianyungang City. Via real-time weather mo- nitoring, accurate and fine forecast and early warning, short-term objective forecast business system of frost in Lianyungang was established for a full range of effective service.
