Hurricane Teddy has transitioned to a large post-tropical cyclone over eastern Canada. Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Teddy's rainfall rates. In addition to the heavy rainfall, Teddy causing destructive waves and strong winds today, Sept. 23, for portions of Atlantic Canada.
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.
University of Warwick astronomers have shown that water vapour can potentially be detected in the atmospheres of exoplanets by peering literally over the tops of their impenetrable clouds.
Former Subtropical Storm Alpha was a short-lived storm that formed and fizzled within 24 hours. NASA-NOAA's Suomi NPP satellite found the remnants of former Subtropical storm Alpha spreading over Portugal and northwestern Spain.
Former Tropical Storm Wilfred weakened in the Central Atlantic Ocean and NASA-NOAA's Suomi NPP satellite provided a visible image after the storm became a trough or elongated area of low pressure.
Data from Southwest Research Institute-led instruments aboard ESA's Rosetta spacecraft have helped reveal auroral emissions in the far ultraviolet around a comet for the first time.
