Global winds could explain record rains, tornadoes. Two talks at a scientific conference this week will propose a common root for an enormous deluge in western Tennessee in May 2010, and a historic outbreak of tornadoes centered on Alabama in April 2011.
Both events seem to be linked to a relatively rare coupling between the polar and the subtropical jet streams, says Jonathan Martin, a University of Wisconsin-Madison professor of atmospheric and oceanic sciences. But the fascinating part is that the change originates in the western Pacific, about 9,000 miles away from the intense storms in the U.S. midsection, Martin says. The mechanism that causes the storms originates during spring or fall when organized complexes of tropical thunderstorms over Indonesia push the subtropical jet stream north, causing it to merge with the polar jet stream. The subtropical jet stream is a high-altitude band of wind that is normally located around 30 degrees north latitude.

Arresting the world's warming and protecting and restoring our natural systems are issues of life and death for much of the world's population" 2004 Nobel Peace Laureate Wangari Maathai (Kenya's Business Daily, Dec. 14, 2007) IPS is intensifying its coverage of both global and local environmental challenges. We look at them from the perspective of the people for whom the ecosphere matters in a direct way: rural dwellers who have little means to protect themselves against adverse conditions; communities that need to switch to sustainable development in order to survive; poor women and children, always the most vulnerable in harsh times.
