NASA analyzed the cloud top temperatures in the newly formed Tropical Cyclone Irondro using infrared light to determine where the strongest storms were located.
Former Tropical Cyclone Herold is now a fading area of low-pressure in the Southern Indian Ocean and NASA's Aqua satellite provided forecasters with a visible image.
Wind shear pushed former Tropical Cyclone Herold apart and infrared imagery from NASA's Aqua satellite showed the system with very little strength remaining.
When NASA's Aqua satellite passed over the Southern Indian Ocean on Mar. 18, it gathered water vapor data that showed wind shear was adversely affecting Tropical Cyclone Herold.
As Tropical Cyclone Herold intensified, its eye appeared more defined in imagery taken by NASA's Terra satellite.
NASA's Terra satellite passed over the Southern Pacific Ocean and captured an image of Tropical Storm Gretel as it was transitioning into an extra-tropical cyclone, northwest of New Zealand.
NASA's Aqua satellite passed over the Southern Indian Ocean and captured an image of a well-developed Tropical Cyclone Herold at hurricane strength, east of Madagascar.
NASA's Terra satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of newly formed Tropical Storm 22S, located near northeastern Madagascar.
Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other suspended particulate matter. Their findings will help to improve the understanding of global processes involved in cloud formation and air pollution and to refine the corresponding models.
NASA's Terra satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of Ex-Tropical Cyclone 21S. Although no longer a tropical cyclone, the system has triggered warnings for heavy rainfall and winds.
