NASA satellite imagery captured tropical cyclones crowding the waters of two oceans in the Southern Hemisphere in recent days.
Three storms were simultaneously active in the Pacific Ocean—a rare event—but satellites also captured a trio of cyclones rolling across the Indian Ocean. The images reveal the intensity of the weather across a broad sweep of the Southern Hemisphere, and showcases the utility of agency satellites in tracking storm systems from low-Earth orbit.
The images were taken by the National Oceanic and Atmospheric Administration NOAA-20 using its Visible Infrared Imaging Radiometer Suite (VIIRS) sensor.
The Pacific storms are named Alfred and Seru, and the Indian Ocean systems are Bianca, Garance, and Honde. In the NASA false color imagery taken on February 26, Garance and Honde are seen toiling on either side of Madagascar, while Bianca sits off Australia’s west coast. Alfred and Seru are east of northern Australia.
