Hurricane Fernanda appears to be weakening on infrared satellite imagery. NOAA's GOES-West satellite imagery on July 19 showed a more disorganized hurricane nearing the Central Pacific Ocean.
NASA Terra satellite provided a clear view of Tropical Storm Greg, located off the southwestern coast of Mexico. Greg is one of three tropical cyclones in the Eastern Pacific Ocean and is the closest to land.
Tropical Storm Don didn't live long before it weakened to a remnant low pressure area in the North Atlantic Ocean.
As Hurricane Fernanda moves toward the Central Pacific, and Tropical Storm Greg moves away from the Mexican coast, a new tropical depression formed in between the two tropical cyclones. NOAA's GOES-West satellite saw the development of Tropical Depression 8E in the Eastern Pacific Ocean on July 18.
NASA's Aqua satellite passed over newly formed Tropical Storm Don gathering temperature data from the compact storm's clouds.
NASA's Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage satellites.
If European countries cooperated better in the field of wind energy, wind power output would fluctuate less. This is the conclusion reached by a group of energy and climate researchers at ETH Zürich and Imperial College London, who for the first time have combined a long-term analysis of predominant weather patterns with Europe-wide wind electricity generation.
Heavy rain resulted in significant flooding in the U.S. Midwest over the week of July 7 to 14, 2017. Using satellite data, NASA estimated the amount of rain that fell over those areas and used satellite data to create 3-D imagery of severe storms.
Hurricane Fernanda is moving through the deep tropics and there's nothing in its way to prevent it from becoming a major hurricane. NASA's Terra satellite took a closer look at the strengthening storm.
Tropical Storm Fernanda continues to strengthen as it moves west through the Eastern Pacific Ocean. NOAA's GOES-West satellite provided an infrared image of the storm on July 13 as it was nearing hurricane strength.
