El Niño is a recurring climate pattern characterized by warmer than usual ocean temperatures in the equatorial Pacific. Two back-to-back 3-D visualizations track the changes in ocean temperatures and currents, respectively, throughout the life cycle of the 2015-2016 El Niño event, chronicling its inception in early 2015 to its dissipation by April 2016.
On Wednesday May 24, 2017, severe weather affected a large area of the eastern United States. That's when the Global Precipitation Measurement mission or GPM core satellite passed over the area and found extremely heavy rainfall and towering clouds in the system.
Astronomers publish predictions of planetary phenomena on Jupiter that informed spacecraft's arrival.
Storms associated with the advancing monsoon in the Northern Indian Ocean's Bay of Bengal were analyzed by NASA with the GPM or Global Precipitation Measurement mission core satellite.
Over the week of May 15, extreme rainfall drenched northeastern Australia and NASA data provided a look at the record totals.
The surfaces of Earth, Mars, and Titan, Saturn's largest moon, have all been scoured by rivers. Yet despite this similarity and the amazingly Earth-like landscapes of Titan complete with valleys, lakes, and mountains, researchers led by City College of New York geologist Benjamin Black report new evidence that the origins of the topography there and on Mars are different from on Earth.
Human activities, like nuclear tests and radio transmissions, have been changing near-Earth space and weather, and have created artificial radiation belts, damaged satellites and induced auroras.
Humans have long been shaping Earth's landscape, but now scientists know that we also can shape our near-space environment with radio communications, which have been found to interact with particles in space.
An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. In the special June issue of Phil. Trans. B researchers of the Netherlands Institute of Ecology (NIOO-KNAW) launch a new approach to these 'extreme' studies.
Heavy rain on Mars reshaped the planet's impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet's surface as we see on Earth.
