NASA Study Projects Warming-Driven Changes In Global Rainfall

A NASA-led study provides new evidence that global warming may increase the risk for extreme rainfall and drought.

The study shows for the first time how rising carbon dioxide concentrations could affect the entire range of rainfall types on Earth.

Analysis of computer simulations from 14 climate models indicates wet regions of the world, such as the equatorial Pacific Ocean and Asian monsoon regions, will see increases in heavy precipitation because of warming resulting from projected increases in carbon dioxide levels. Arid land areas outside the tropics and many regions with moderate rainfall could become drier.

The analysis provides a new assessment of global warming’s impacts on precipitation patterns around the world. The study was accepted for publication in the American Geophysical Union journal Geophysical Research Letters.

The models project for every 1 degree Fahrenheit of carbon dioxide-induced warming, heavy rainfall will increase globally by 3.9 percent and light rain will increase globally by 1 percent. However, total global rainfall is not projected to change much because moderate rainfall will decrease globally by 1.4 percent.

Heavy rainfall is defined as months that receive an average of more than about 0.35 of an inch per day. Light rain is defined as months that receive an average of less than 0.01 of an inch per day. Moderate rainfall is defined as months that receive an average of between about 0.04 to 0.09 of an inch per day.

Areas projected to see the most significant increase in heavy rainfall are in the tropical zones around the equator, particularly in the Pacific Ocean and Asian monsoon regions.

Some regions outside the tropics may have no rainfall at all. The models also projected for every degree Fahrenheit of warming, the length of periods with no rain will increase globally by 2.6 percent. In the Northern Hemisphere, areas most likely to be affected include the deserts and arid regions of the southwest United States, Mexico, North Africa, the Middle East, Pakistan, and northwestern China. In the Southern Hemisphere, drought becomes more likely in South Africa, northwestern Australia, coastal Central America and northeastern Brazil.


Wind Sparks Wildfires in Oregon, USA

Winds gusting to 40 mph wreaked havoc on parts of Central Oregon Saturday, toppling trees that blocked roads and downing power lines that sparked at least two small wildfires and forced two dozen people to evacuate their homes.

California Wildfires

Nearly 2000 California firefighters are battling a wildfire north of Malibu, as one of the fiercest blazes shuts the Pacific Coast Highway for a second day. The blaze is now nearly 60% contained. The wildfire raging on the coast of southern California had nearly tripled in size.


Roundup of Global Volcanic Activity:

Cleveland (Aleutian Islands, Alaska): A possible explosion occurred this morning at the volcano at 5:00AM AKDT (13:00 UTC) by AVO infrasound recorders. The infrasound signals suggest that this was a relatively short duration, low-level explosion. No eruption cloud has been detected in available satellite views. AVO received no other reports of activity.
