Because of the long intervening distance, the radar only saw the middle and upper levels of the storm. That is illustrated in an eastward-looking vertical cross-section that I constructed using this 0.5o beam-tilt image as reference. Also, see this 3-D view looking NE across the storm at the same time.
At landfall, the beam entered the stadium-shaped eye at about 23,000 feet aloft and left it at 26,000 feet. As the beam got further south, toward far southern Dade and the Upper Keys, it overshot more and more of the storm's rain. Because of that, the hurricane looks lopsided; however, it was actually much more dense and symmetric than shown here. It also was well beyond the rangeof MLB velocity products. Still, the data is prized because it offers the only opportunity for a complete radar animation of Andrew as it tracked entirely across South Florida.
The loop can be stopped, restarted, and advanced one frame forward or backward at a time manually, usng the controls at the top. You also can speed up or slow down the animation using the speed bar.
