Tropical Storm Kirk formed on Saturday, Sept. 22. By Monday, Sept. 24, Kirk lacked the closed circulation that is a prerequisite for tropical cyclone status. The NOAA-20 satellite provided a visible image of the storm at its peak.
NASA's Terra satellite provided an infrared look at Tropical Storm Trami, located just over 100 miles from Guam on Sept. 21, 2018. Infrared data provides temperature information that showed two areas of the highest, coldest cloud tops and most powerful storms within the tropical storm.
At NASA's Goddard Space Flight Center in Greenbelt, Md. data was used to create a map of rainfall generated by Super Typhoon Mangkhut.
NASA's Aqua satellite provided an infrared look at fading Post-Tropical Cyclone Florence's clouds, revealing where the strongest thunderstorms were located. Those strong thunderstorms stretched from the Mid-Atlantic to New England.
NASA's Aqua satellite provided an infrared look at Tropical Depression Joyce and found wind shear was pushing the bulk of clouds and showers to the east of the center.
While scientists fear that rising temperatures could unleash a 'bomb' of carbon from Earth's soil carbon reservoirs, a new FSU study suggests these reservoirs might actually be more stable than predicted.
On Sunday, Sept. 16, 2018, Typhoon Mangkhut had made landfall in southern China and Hurricane signal #10 was still in force. NASA's Aqua satellite passed over the storm and captured an image that showed the storm after landfall.
NASA estimated the precipitation generated by Hurricane Florence from Sept. 10 through 17 as it approached North Carolina and days after it made landfall. On Sept. 17, 2018, Florence's remnant rainfall was moving up the Appalachian Mountains into the Mid-Atlantic.
Post-tropical cyclone Helene developed off the west coast of Africa and moved north then northeast where it is now raining on parts of Ireland and the United Kingdom. Clouds and rainfall connected to Helene are already affecting those countries.
The first tropical cyclone of the Southern Indian Ocean season, 01S, formed on Sept. 15 and was already fizzling two days later. Visible satellite imagery from NASA's Aqua satellite revealed recently developed tropical cyclone 01S was already fading.
