Monsoon rains leave lasting traces in trees

2013-06-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Environment Health: A tree's annual growth cycle creates a record of good seasons--and poor ones. Analyzing ring patterns in living and dead wood can help scientists date ancient ships or reconstruct changing climates. In the U.S. Southwest researchers rely on tree rings to track changes in the seasonal monsoon rains that deliver about half of New Mexico and Arizona's precipitation. In the June issue of Scientific American Connie Woodhouse, associate professor in the School of Geography and Development at the University...

Asian monsoon is getting predictable

2013-04-24 00:48:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: The summer rainy season is especially important for securing the water and food supplies for more than a billion people. Its variations can mean the difference between drought and flood. Now a Scripps Institution of Oceanography, UC San Diego-led study reports on a crucial connection that could drastically improve the ability of forecasters to reliably predict the monsoon a few months in advance. Yu Kosaka and Shang-Ping Xie from Scripps and colleagues from NOAA found that a winter appearance...

Natural climate swings contribute more to increased monsoon rainfall than global warming

2013-03-20 23:04:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Natural swings in the climate have significantly intensified Northern Hemisphere monsoon rainfall, showing that these swings must be taken into account for climate predictions in the coming decades, a new study finds. The findings are published in the March 18 online publication of the Proceedings of the National Academy of Sciences. Monsoon rainfall in the Northern Hemisphere impacts about 60% of the World population in Southeast Asia, West Africa and North America. Given the possible impacts...

Monsoon failure key to long droughts in Southwest

2013-03-11 22:48:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Long-term droughts in the Southwestern North America often mean failure of both summer and winter rains, according to new tree-ring research from a University of Arizona-led team. The finding contradicts the commonly held belief that a dry winter rainy season is generally followed by a wet monsoon season, and vice versa. The new research shows that for the severe, multi-decadal droughts that occurred from 1539 to 2008, generally both winter and summer rains were sparse year after year. "One...
