Tropical Storm Isaias made landfall late on Aug. 3 and by today, Aug. 4, the huge storm stretched from Virginia to Maine. NASA satellites have been providing forecasters with rainfall rates, cloud top temperatures, storm extent and strength as Isaias batters the U.S. East Coast.
NASA's Aqua satellite provided a look at Typhoon Hagupit as it was nearing landfall in southeastern China.
Ecologists from the South China Botanical Garden of the Chinese Academy of Sciences have identified multiple exogenous factors that can affect the onset of wood formation and quantified the key drivers for secondary growth resumption in Northern Hemisphere conifers.
New system infuses 'R0' models with climate information to help public health agencies forecast places and times when environmental conditions might enhance transmission of dengue, Zika and other Aedes-borne diseases
NASA's satellites were working overtime as they snapped pictures of the large Apple Fire in Banning Canyon near San Bernardino, California on Aug. 02, 2020. This fire began on July 31, 2020 and the cause of the fire is still under investigation. To date the fire has consumed 20,516 acres and is 5% contained.
NASA's Aqua satellite obtained visible and water vapor imagery as Tropical Storm Isaias continued moving along the east coast of Florida. On Aug. 3, 2020, warnings and watches stretched from Florida to Maine.
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of Typhoon Hagupit in the Northwestern Pacific Ocean that showed the development of an eye as it quickly intensified. Imagery also showed a thick band of thunderstorms that resembled a giant tail, spiraling into the powerful storm.
Despite recent reports of lower COVID-19 incidence among high-altitude populations, current data is insufficient to conclude that high altitude is protective against the SARS-CoV-2 virus.
When NASA's Aqua satellite passed over the North Atlantic Ocean, it gathered water vapor data on Isaias, while NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image that showed a more organized tropical cyclone.
Why is the sea surface temperature of the northern tropics in the summer months often lower than expected? This question was investigated by a German-American team of scientists led by the GEOMAR Helmholtz Centre for Ocean Research Kiel. Their results, which have now been published in the international journal Nature Communications, show that a short-term, wind-driven wave phenomenon provides very efficient vertical mixing and cooling of the upper water layer.
