The length of the arrows also corresponds to the horizontal speed. Points along the profile are used as seeds for the streamribbon integration. The visualization for the profile marked 2 can help illustrate the vortex shedding described earlier. Here is a sample image and animation for the same forecast. Five different surface variables have been selected in a combined visualization.
Precipatable water is shown as pseudo-color.
Wind velocity is illustrated as vector arrows, colored by speed. Colored line contours of maximum reflectivity in increments of 3 dbZ are shown. These planar representations are deformed vertically by relative humidity to create a shaded surface. Finally, temperature values at discrete locations are also shown by value on the surface. Any of the surface and upper air fields available from the model can be visualized with any of these methods.
