Paper Abstract

Current research efforts involve using a supercomputing-visualization facility for climate and weather simulations and data visualization applications. The Numerical Models of the National Center for Atmospheric Research, the Community Climate Model version 2 (CCM2) and the Mesoscale Model version 5 (MM5), are currently running on the VPX240 and VPP500 supercomputers and are generating climate and weather data. Workstations and microcomputers connected to the supercomputers have been used to visualize the data. AVS macro-module networks and AVS/Express projects were developed on a SGI workstation to study climatological and meteorological parameters. The specific visualization topics worked on are: comparisons of AVS and AVS/Express visualization systems; comparisons of iso- surface and iso-volume techniques; and a multivariate data visualization system using multi- windows and a composite of data fields. A weather simulation case has been studied by using the multivariate data visualization system and visualization techniques. The results show that common weather features such as fronts, mesoscale high pressure systems, and clouds can be identified easily. Data dissemination and visualization using internet browsers have been successfully conducted across the Pacific Ocean.
