NASA's Terra satellite obtained visible imagery of Tropical Storm Dolphin as it continued moving north though the Northwestern Pacific Ocean on a track toward east central Japan.

NASA analyzed the cloud top temperatures in Tropical Storm Lowell using infrared light to determine the strength of the storm. Infrared imagery revealed that the strongest storms were around Lowell's center and in its southern quadrant because of northerly wind shear.

NASA's Aqua satellite used infrared light to identify strongest storms and coldest cloud top temperatures in Hurricane Teddy as it nears eastern Canada. Teddy has triggered multiple warnings and watches.

NASA's Aqua satellite analyzed Tropical Storm Beta in infrared imagery to determine where the strongest parts of the storm were located. Beta is expected to stall inland over Texas today, Sept. 21, and heavy rains will continue over portions of the middle and upper Texas coast.

Tropical Storm Paulette just reformed in the central North Atlantic Ocean today, Sept. 22. Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Paulette's rainfall rates.

Fairy circles are one of nature's greatest enigmas and most visually stunning phenomena. Researchers led by Göttingen University have now collected detailed data to show that Alan Turing's model explains the striking vegetation patterns of the Australian fairy circles. In addition, the researchers showed that the grasses that make up these patterns act as "eco-engineers" to modify their hostile and arid environment, keeping the ecosystem functioning. Results were published in the Journal of Ecology.

NASA's Terra satellite obtained visible imagery of recently formed Tropical Depression 14W as it strengthened into a tropical storm. Terra satellite imagery showed the storm was organizing.

Analysis published in Scientific Reports is based on climate models for the mid-Pliocene period, which occurred 3 million years ago and shared characteristics with present-day warming.

Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Hurricane Teddy's rainfall rates as it approaches Bermuda on Sept. 21. Teddy is a large hurricane and growing. It is also churning up seas all the way to the U.S. and Canadian coastlines.
