Sound generated by seismic events on the seabed can be used to determine the temperature of Earth's warming oceans.
Subtropical Storm Alpha has formed near the coast of Portugal, becoming the first named storm using the Greek Alphabet list, now that the annual list of names is exhausted. NASA's Aqua satellite obtained visible imagery of the new storm.
NASA-NOAA's Suomi NPP satellite provided an infrared image of Tropical Depression 22 in the Gulf of Mexico during the early morning hours of Sept. 18. TD22 is expected to become a tropical storm, according to the National Hurricane Center (NHC).
The list of hurricane names is officially used up with the development of the 23rd tropical cyclone of the year. Tropical Storm Wilfred just formed in the Eastern Atlantic Ocean today, Sept. 18. Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Wilfred's rainfall rates.
Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Hurricane Teddy's rainfall rates. Teddy is a major hurricane in the Central North Atlantic Ocean.
Tropical Storm Noul made landfall in central Vietnam on Sept. 17 and NASA-NOAA's Suomi NPP satellite captured an image of the storm over Laos. Noul was weakening as it moves toward Thailand where it is forecast to dissipate.
Large volcanic eruptions can help to forecast the monsoon over India - the seasonal rainfall that is key for the country's agriculture and thus for feeding one billion people. As erratic as they are, volcanic eruptions improve the predictability, an Indian-German research team finds. What seems to be a paradox is in fact due to a stronger coupling between the monsoon over large parts of South and South-East Asia and the El Niño phenomenon after an eruption.
Using high resolution paleoecological information obtained from fossilized footprints, a new study published in Science Advances presents ~120 thousand-year-old human and animal footprints from an ancient lake bed in northern Arabia. These findings represent the earliest evidence for humans in this part of the world and show that human and animal movements and landscape use were closely linked.
Powerful storms with heavy rainmaking capabilities appeared over the coast of central Vietnam in NASA provided infrared imagery on Sept. 17.
An early morning infrared image of Hurricane Teddy taken from NASA-NOAA's Suomi NPP satellite shows the proximity of the strengthening hurricane to the Lesser Antilles island chain and Puerto Rico. Teddy is a major hurricane on the Saffir-Simpson Hurricane Wind Scale.
