Hurricane Katrina (2005) hindcast using WRF model was shown in this movie. We utilized DVR (Direct Volume Rendering), image, flow, 2D technique of VAPOR for visualization of hurricane. This movie aims to show the varying distribution of strong wind (above 17m/s) of hurricane instead of showing cloud, which is widely used in other visualizations. The winds were expressed by both flow tracking and 3-d visualization using U, V, W variables. The terrain of the United States was expressed by 3-d image, georeference and height options. Colors of realistic sea were expressed by modification of sea surface temperature (SST) variable.
