Abstract: A high-speed electronic computer has been programmed to prepare cloud and precipitation forecasts for the Northern Hemisphere. The basic input data are derived from the Joint Numerical Weather Prediction Unit's two-level ...

Abstract: A series of 35-mm. color slides and 16-mm. motion pictures of clouds were taken from a jet aircraft flying at about 30,000 ft. The aircraft flew from Honolulu to Papeete to Los Angeles and returned to Honolulu, twice ...

Abstract: Computer-prepared analyses of the upper-air wind field are being made for several levels for the tropical Pacific Ocean area of both the Northern and Southern Hemispheres. Computer analyses compare favorably with conventional ...

Abstract: In solving the differential equations used in numerical weather prediction, one resorts to the use of finite-difference techniques. In the barotropic model it is assumed that the absolute vorticity is conserved. Even though ...

Abstract: A series of barotropic forecasts has been prepared for several upper-air levels in the tropical Pacific. The governing equation is the vorticity equation for a barotropic non-divergent atmosphere. The input data are ...
