Sensing an Odd-Shaped Cyclone

Short-lived Tropical Cyclone Flamboyan formed southwest of the island of Sumatra and reached tropical storm intensity on April 28. It had peak winds of about 80 mph on April 29, after which the storm weakened. Flamboyan's odd shape is due to wind shear pushing the storm's center to the southeast.

A NASA Eye in the Sky

This image was created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite (launched in 2002). MODIS provides global coverage every 1-2 days. A second MODIS sensor is aboard NASA's Terra satellite (launched in 1999).


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.
