Abstract : An atmospheric coastal mesoscale model is visualized using a high speed graphical computer workstation. Output from a 36-h model forecast of the Naval Postgraduate School (NPS) research version of the Naval Research Laboratory (NRL) limited area grid model is displayed at 30 minute time steps. The NPS/NRL model is centered on the California coastal region. Using the graphical software package, VIS-5D, three-dimensional scenes are developed that show the interrelation of model parameters which aid in understanding model output. The visualization is used to evaluate wind flow, temperature and moisture patterns, shortwave and longwave radiation parameterization, and cloud simulations for the time period 0000 UTC 02 May 1990 to 1200 UTC 03 May 1990. Additionally, model output is used to compute tactical displays of radar propagation used by the naval fleet Numerical modeling. Three dimensional visualization, Coastal meteorology, Mesoscale,
