NASA sees small Tropical Storm In-fa becoming extra-tropical

On Nov. 25, NASA's Terra satellite saw strong convection and thunderstorms from Tropical Storm In-fa were being pushed northeast of the center by wind shear.Tropical Storm In-fa was becoming an extra-tropical storm as it tracked toward the island of Iwo To, Japan in the western North Pacific Ocean. NASA's Terra satellite captured an infrared...

NASA's GPM finds extreme rainfall in Typhoon In-fa

On Nov. 23, GPM saw In-fa dropping rain at an extreme rate of over 266 mm (10.5 inches) per hour in storms just to the northwest of the typhoon's eye where thunderstorms reached altitudes of over 18 km (11.2 miles).The Global Precipitation Measurement mission known as GPM passed over Typhoon In-fa and found extreme rainfall occurring in the storm.

Low-oxygen 'dead zones' in North Pacific linked to past ocean-warming events

A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led...

Declining snowpacks may cut many nations' water

This image shows a snowpack in the Lesser Caucasus mountains of northeastern Turkey, elevation about 2,700 feet, late April 2012. The lowlands below depend heavily on seasonal snowmelt, projected to decline in this region and others in coming decades, due to global warming.Gradual melting of winter snow helps feed water to farms, cities and ecosystems across much of the world, but this resource may soon be critically imperiled. In a new study,...

NASA adds up rainfall from 2 historic Yemen tropical cyclones

On Nov. 8 GPM saw intense rain rates of up to 100 mm per hour (~4 inches per hour) in the southern half of the eyewall surrounding Megh's center.One week ago to the day Cyclone Chapala, the first Category 1 cyclone to strike Yemen in recorded history made landfall in Yemen, then a second tropical cyclone named Megh...

Massive 'development corridors' in Africa could spell environmental disaster

This photo shows a savannah elephant, one of many animals expected to be affected by poaching with a dramatic expansion of African roads.Saharan Africa, dozens of major 'development corridors,' including roads, railroads, pipelines, and port facilities, are in the works to increase agricultural production, mineral exports, and economic integration. And, if all...

NASA study suggests carbon content of temperate forests overestimated

The landscape shown here is not a photograph but a 3-D visualization obtained using lidar and aerial imagery. Lidar is a remote sensing technique that can be used to digitally measure the heights and crown dimensions of trees, not just for a small sample but for every tree across a landscape.Digital measurements of millions of trees indicate that previous studies likely overestimate the amount of carbon stored by temperate U.S. forests, according to a new NASA study.

Earth's magnetic field is not about to flip

This is an artistic impression of how auroras could be more widespread under a geomagnetic field much weaker than today's.The intensity of earth's magnetic field has been weakening in the last couple of hundred years, leading some scientists to think that its polarity might be about to flip. But...
