Hurricane Ida has a concentrated center of strong winds in this visualization of the storm’s wind field as observed by the QuikSCAT satellite on November 9, 2009.
Although Mirinae was weakening, its winds maintained the classic spiral structure associated with well-organized tropical cyclones in this image of the storm’s wind structure on November 1, 2009.
Acquired September 9, 2009, this image uses color coding and barbs to indicate wind speed and direction for Tropical Storm Mujigae. The image captures the storm center immediately west of the Philippine island of Luzon.
In this image of wind speed and direction, Hurricane Fred exhibits a distinctive “s” shape—a structure left over, perhaps, from its time as a Category 4 storm.
