Stay South of Thunderstorm Paths, Says Purdue Scientist
November 17 — Damaging winds can occur in previously overlooked places within a thunderstorm, according to a Purdue University earth scientist; a finding that could help meteorologists save lives and reduce injuries by issuing more accurate storm warnings. (Purdue University press release) More

Climate Models Predict Wetter Winters, Warmer Summers in the West
November 13 — New computer models producing simulations of how ecosystems and fire regimes could change, show the Western United States may get wetter during the winter and experience warmer summers throughout the 21^st century. (USDA Forest Service, Pacific Northwest Research Station press release) More

Iceberg's End Caught by Envisat
November 10 — A series of Envisat Advanced Synthetic Aperture Radar (ASAR) instrument images acquired between mid-September and October record how the world�s largest iceberg was split by the onslaught of powerful storms as its own weight kept it fixed on the floor of Antarctica's Ross Sea. (European Space Agency) More

Explanation Offered for Antarctica�s Blood Falls
November 7 — Work recently published in Nature announces a significant correlation between sediment deposition in two Bolivian rivers, which flow into one of the principal tributaries of the Amazon, and climatic events of the ENSO (El Niño Southern Oscillation) type. (Institut de Recherche Pour le D�veloppement press release) More

Ice-Cores May Yield Clues to 5,000-Year-Old Mystery
November 6 — Ice cores received from two tropical ice caps in the Andes mountains by Ohio State University scientists may contain clues that link ancient events that changed daily life in South America, Europe, and Asia. (Ohio State University press release) More

Nitrates Abundant in Arid Southwest
November 6 — A new study reveals desert soils in the Southwest United States may be nutrient poor, but the subsoils below the surface are rich in nitrate, which raises questions about how desert ecosystems work. More

Thunderstorm Research Shocks Conventional Theories
November 5 — A Florida Tech professor finds lightning is not produced by large, unseen electric fields inside storms, but the true triggering mechanism remains a mystery. (Florida Institute of Technology press release) More

Warming Waters Identified as Cause of Marine Life Depletions Off California
November 5 — A recent study led by a scientist at Scripps Institution of Oceanography has found warming ocean temperatures as the likely driving force behind the 25-year deterioration of marine life along the western coast of the United States.
