摘要
以引进的美国 Penn State/NCAR 中尺度模式(MM2和 MM4)为基础,按照实时业务预报需要和我国资料特点,在 PC/386微机上研制了中尺度业务预报试验数值模式系统。在1989-1990年进行的实时业务预报试验中,该系统运行稳定,预报时效能满足实时业务预报要求,预报结果对12—24小时短期天气预报具有参考价值,适合于省(市)级气象台站等业务单位使用。
A 3-D mesoscale operational numerical model system(MOMS)is developed on a microcom-puter PC-386 according to the requirements of real-time operational forecast and data availabili-ty.The system including data input,objective analysis,forecast processing and results output isrun automatically.It can provide prognosis and precipitation forecast at any given interval within24-hour period.The results are displayed on terminal with color graphics.The system was in oper-ation in the summer experiments of Beijing-Tianjin-Hebei mesoscale experimental base during1989 to 1990,and provided numerical forecast product services during the period of 11th AsianGames.The experimental operational forecast with this system was also carried out in weatherforecast stations of Inner Mongolia Autonomous Region and Hebei Province in 1990.The resultsshow that the model system operates steadily and can meet,with regard to timelyness,the require-ments of real-time operational forecast.The forecasts provided by the system contribute positivelyto making 12—24 hours short range forecast.
