Facing a climate crisis, we may someday spray sulfur dioxide into the upper atmosphere to form a cloud that cools the Earth, but suddenly stopping the spraying would have a severe global impact on animals and plants, according to the first study on the potential biological impacts of geoengineering, or climate intervention.
NASA found heavy rainfall in Tropical Cyclone Berguitta as it closed in on Mauritius and Reunion Islands. On Jan. 18, NASA's Terra satellite captured an early morning visible image that showed the center of the storm just south of Mauritius and the storm blanketing both islands. Warnings were in effect for both islands. A tropical cyclone alert class 3 is in effect for Mauritius and La Reunion is on Orange Alert.
Heavy rain surrounded Tropical Cyclone Berguitta as it continued to move toward the island of Mauritius in the Southern Indian Ocean. NASA calculated the rate in which rain was falling within the hurricane-strength storm in the Southern Indian Ocean.
Aerosol indirect effect (AIE) can significantly affect climate change and is one of the largest uncertainties in climate change studies. To date, only a few AIE studies using satellite measurements have been carried out in China, and no such study has been done using ground-based measurements. The AIE can only be assessed accurately from aircraft or ground-based measurements. The first comprehensive investigation into the AIE over this polluted region is presented.
Using the power of Japan's K computer, scientists from the RIKEN Advanced Institute for Computational Science and collaborators have shown that incorporating satellite data at frequent intervals -- 10 minutes in the case of this study -- into weather prediction models can significantly improve the rainfall predictions of the models and allow more precise predictions of the rapid development of a typhoon.
NASA's Terra satellite passed over the Southern Indian Ocean and saw Tropical Cyclone Berguitta moving southwest toward the island of Mauritius. A tropical cyclone alert class 2 is in effect for Mauritius.
ETH researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago -- and that the increased melting of ice in summer is linked to recurring periods of fair weather.
NOAA's JPSS-1 satellite provided a visible image of the tropical storm after it made landfall along the Pilbara Coast in the northwestern part of Western Australia.
Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research published in Nature Communications is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.
Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on Jan. 9. NASA calculated the amount of rain fall between Jan. 8 and 10, 2018 and calculated the potential for landslides.
