NASA's Aqua satellite got a close-up of Typhoon Kilo's eye as it moved through the Northwestern Pacific Ocean.
The Eastern Atlantic Ocean continues to generate storms, and as satellites are watch Tropical Storm Fred fade over the next couple of days, a new area of low pressure has moved off the coast of western Africa.
Hurricane Ignacio continues weakening as it moves over the colder waters of the Pacific Ocean far to the north of Hawaiian Islands. The Global Precipitation Measurement of GPM mission core satellite flew over Ignacio and analyzed the weaker storm's precipitation.
Hurricane Jimena is on a downward spiral and is expected to continue weakening. NASA-NOAA's Suomi NPP satellite flew over Hurricane Jimena and saw the strongest thunderstorms were on its southern and northeastern sides. Jimena is expected to bring rough surf to the Hawaiian Islands over the weekend of Sept. 5 and 6.
A new model for snow-fed mountain wetlands projects that this year's dry conditions could be common by the 2070s, affecting the Cascades frog and other mountain species.
As climate change accelerates ice melt in the Arctic, polar bears may find caribou and snow geese replacing seals as an important food source, shows a recent study. The research, by Linda Gormezano and Robert Rockwell at the American Museum of Natural History, is based on new computations incorporating caloric energy from terrestrial food sources and indicates that the bears' extended stays on land may not be as grim as previously suggested.
Tropical Storm Kevin's center was several hundred miles south-southwest of Baja California when NASA's Aqua satellite passed overhead and saw some associated high clouds streaming over the peninsula.
A new study published in Park Science shows that nearly 90 percent of visitors to a major national park highly valued the night sky and wanted the National Park Service to take steps to reduce light pollution. The study also established a threshold below which visitors found light pollution of the night skies unacceptable, a standard park staff can manage toward using a variety of strategies in and out of the park.
With limited funding available, a common strategy for conservation planners is to identify areas of high species richness and endemicity, but this approach ignores evolutionary history and so may overlook important regions for conservation. A recent study, available in Applications in Plant Sciences, argues for the importance of incorporating phylogenetic diversity metrics in conservation planning. The study tests a dozen commonly used metrics so users can determine which metrics should be used in which situations.
Upper-level westerly winds have been affecting Tropical Storm Fred in the far eastern Atlantic Ocean and continue to do so today, September 3. Infrared imagery from NASA's Aqua satellite showed the highest thunderstorms pushed southeast of the storm's center.
