SUPPLEMENTARY NOTES
ABSTRACTA nowcast/short-range forecast method, over the domains of approximately 100 km by 100 km with grid resolution of 1.5 to 2.0 km, has been developed for the Integrated Meteorological System (IMETS). Meteorological data available in the IMETS, including Mesoscale Model Version 5 (MM5) forecast, surface, and upper-air sounding data, are used for the computation. Three-dimensional distributions of temperature, dew-point temperature, and horizontal wind vector components can be forecasted. The method is evaluated over two different areas: Dallas (TX) and Denver (CO). It was shown that the present method was valid up to 3 h over the Dallas domain, and up to 2 h over the Denver domain. Although further studies are needed over different areas and seasons, it is tentatively concluded that the present forecasting method can be used at least for 2 h.
