Harvey's Rainfall and Structure Seen by GPM (VIDEO)
Caption
The animation shows rain rates derived from GPM's GMI microwave imager (outer swath) and dual-frequency precipitation radar or DPR (inner swath) overlaid on enhanced infrared data from the GOES-East satellite.
Harvey's cyclonic circulation is still quite evident in the infrared clouds, but GPM shows that the rainfall pattern is highly asymmetric with the bulk of the rain located north or east of the center. A broad area of moderate rain can be seen stretching from near Galveston Bay to north of Houston and back well to the west. Within this are embedded areas of heavy rain (red areas); the peak estimated rain rate from GPM during these overpasses was 96 mm/hr (~3.77 inches per hour). The animation was created at the NASA's Scientific Visualization Studio, at NASA's Goddard Space Flight Center, Greenbelt, Md.
With Harvey's circulation still reaching out over the Gulf of Mexico the storm is able to draw in a continuous supply of warm moist air to sustain the large amount of rain it is producing.
