Rainy weather patterns in the southwestern United States are becoming less frequent. It’s a trend that could signify the region’s transition to a drier climate state—one characterized by megadroughts and dramatic changes to the environment.
For the first time since records began, two tropical storms—one in the Atlantic and one in the Pacific—have appeared at the same time in January. Named Alex and Pali, these storms are being fueled by unusually warm surface waters.
Unusually heavy rainfall and severe storms in parts of Missouri and Illinois late last month are now causing the Mississippi River to surge, threatening a number of communities with severe flooding.
In the early 1920s a researcher spent his days watching vortexes in water circle around each other. A hundred years later, we do the same thing—but we do it from space as we wonder which way a tropical storm is going to go.
It was an uncharacteristically quiet hurricane season in the Atlantic, but the same cannot be said for the eastern Pacific and central Pacific basins, which got absolutely hammered this year. New maps by NASA and Unisys Weather show the extent of this year’s storm season.
Yemen is not known for its tropical storms, yet the desert country is now facing its second major cyclone within a single week. Ravaged by civil war—and still recovering from Cyclone Chapala—Yemen is once again preparing for a bout of rainfall and flooding.
We now know that climate change is a lot more complicated than the world just getting hotter or colder. It will have all kinds of effects, and scientists studying the African savanna think they’ve found one of them.
This extraordinary image of an apparent floating city has created a stir among conspiracy theorists, but a well-known optical illusion is the likely explanation for the phenomenon.
In just two hours, in 1894, a wall of flame took out six Minnesota towns. A lot of factors came together to create the firestorm, but the main one was a nasty, but innocuously-named phenomenon called a “temperature inversion.”
NASA’s Terra satellite recently captured this stunning photo of Saharan dust wafting over the Atlantic ocean. It’s one of several outbreaks this summer that some speculate may be contributing to this year’s relatively peaceful storm season.
Ocean conditions in the Pacific Ocean are increasingly suggestive of a potent El Niño event later this year. While that might seem like good news to the water-starved regions of the United States, the resulting torrential rains could be exceptionally hazardous.
This is super typhoon Soudelor, captured by NASA instruments as it attained Category Five status on the Saffir-Simpson Wind Scale earlier today. Its eye is 12 nautical miles wide; its winds are up to 161 miles per hour; and the extremely rough waves below it are up to 48 feet high.
Europe’s MSG-4 geostationary weather satellite is up and running after its launch on July 15. Earlier today, it’s Spinning Enhanced Visible Infrared Imager (SEVIRI) snapped its first image of Earth. And yes, we are impressed.
The wall of wind-driven ocean that accompanies a hurricane is called a “surge” for a reason: This isn’t a gentle rising of the water level, it’s violent and destructive—sometimes more so than the hurricane’s winds. This hurricane season, for the first time, the National Hurricane Center will be testing a prototype…
Astronomers have been unable to explain the sudden but fleeting appearance of massive plumes high up in the Martian atmosphere. Rising to altitudes of over 155 miles (250 km), these hazy structures are forcing scientists to re-evaluate what they know about the Martian atmosphere.
Via the US National Weather Service comes this staggering footage of a lightning bolt making matchsticks of a tree in Upstate New York.
A gigantic storm is set to hit the West Coast later today, bringing with it over a foot of rain. It's what meteorologists call an Atmospheric River—but what is that, exactly?
These aren't film frames from The Empire Strikes Back, even while they look exactly like Rebel Alliance's Echo Base, ion cannon included. They are not on the icy surface of planet Hoth, but much nearer, in the Artic circle.
