NASA's unmanned Global Hawk aircraft flew over Tropical Storm Dolly on Sept. 2 and gathered data. The plot shows wind speeds and wind barbs at 850 and 150 millibars. It showed Winds at low levels up to about 35 to 40 knots and a reasonably depicted cyclonic circulation.
In the image, the dropsonde data gathered from NASA's Global Hawk were adjusted over the satellite image of the storm to compensate for the storm's movement. As a result, although the image makes dropsonde data look as if it were over eastern Mexico, there were no drops over the country. The data was just shifted to match the satellite image. All dropsondes were dropped over the Gulf of Mexico.
