Abstract:Based on the data obtained from three meteorological stations for 40 years in Diqing, Yunnan Province, a study was conducted on the forecasting methods of meteorological indexes for tourism. In combination with the temporal-and spatial-scale theories of weather systems and the related statistical results, various meteorological indexes are discussed. The specific meteorological indexes were obtained through adjusting longitude, latitude, and vegetation distribution based on the weather forecasts and relative observation data provided by the nearest weather stations. The techniques of synoptic, numerical method and conventional forecasts were applied in software development. The forecasting system of UV index, suitability index, dressing index, fire danger class, and meteorological indexes for tourism was developed by using the FORTRAN and VB computer language. The software has been put into operation.
