On April 8, Tropical Cyclone Harold is a major hurricane, a Category 4 on the Saffir-Simpson Hurricane Wind Scale, as it exits Fiji and heads toward the island of Tonga. NASA used satellite data to calculate the rainfall generated by this powerful and destructive storm in the Southern Pacific Ocean.
Tropical Cyclone Harold brought heavy rains and hurricane-force winds to Vanuatu and was moving toward Fiji when NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the storm.
One of NASA's satellites that can measure the rate in which rainfall is occurring in storms passed over powerful Tropical Cyclone Harold just after it made landfall in Vanuatu in the Southern Pacific Ocean.
NASA analyzed Tropical Storm Irondro's rainfall and found heaviest rainfall was being pushed far southeast of the center because of strong wind shear.
Nuclear bomb tests during the Cold War in the 1950s and 1960s have helped scientists accurately estimate the age of whale sharks, the biggest fish in the seas, according to a Rutgers-led study. It's the first time the age of this majestic species has been verified. One whale shark was an estimated 50 years old when it died, making it the oldest known of its kind. Another shark was an estimated 35 years old.
NASA-NOAA's Suomi NPP satellite passed over the Southern Pacific Ocean and provided forecasters with a visible image of newly formed Tropical Cyclone Harold. Harold formed near the Solomon Islands and now threatens Vanuatu, which has already issued some warnings.
As Tropical Cyclone Irondro continues to move through the Southern Indian Ocean, NASA's Terra satellite saw the storm developing an eye as it continued to intensify.
NASA analyzed the cloud top temperatures in the newly formed Tropical Cyclone Irondro using infrared light to determine where the strongest storms were located.
Dropping Mentos® candies into a bottle of soda causes a foamy jet to erupt. Although science fair exhibitors can tell you that this geyser results from rapid degassing of the beverage induced by the candies, the precise means by which bubbles form hasn't been well characterized. Now, researchers reporting in ACS' Journal of Chemical Education used experiments in the lab and at various altitudes to probe the mechanism of bubble nucleation.
A new Caltech-JPL study determines the impact of the severe 2019 floods, and offers scientists a new tool for measuring regional-scale carbon dioxide absorption by plants.
