Cloud/Icing/Visibility Analysis System (CIVAS) and Forecast Development Plan.
Abstract
Geo-Atmospherics Corporation previously developed atmospheric models, meteorological data interpretation techniques, and computer software to provide a Cloud/Fog/Analysis System (CFAS) and Cloud/Fog Application Routines (CFAR). The CFAS assimilates the four-dimensional distribution of weather information by taking into account type, age, and location of meteorological observations to perform an objective analysis to specify each weather variable on a moveable three-dimensional array of grid points. This data base generated by CFAS can be used individually or its parts analyzed to tailor operational products to a given application. Our CFAR was developed to interrogate the CFAS data base, extract, analyze, and display a map of each chosen parameter, i.e., sky cover, ceiling, visibility, precipitation, severe weather, cloud base, cloud top, and cloud amounts within nine different layers extending from the surface to 3000 meter altitude, the highest level of interest to Army aviation. These techniques have been expanded to develop a Cloud/Icing/Visibility Analysis System (CIVAS) to deduce the three-dimensional distribution of clouds, aircraft icing threat, and visibility, on a horizontal grid scale of 5 km.
