Pacific Ocean Temperatures Could Predict Where Tornadoes May Strike
2013-10-18 14:14:05

[WATCH VIDEO: Predicting Tornadoes] Brett Smith for redOrbit.com - Your Universe Online When and where a tornado will strike is extremely hard to predict, but weather researchers from the University of Missouri-Columbia have found temperatures in the Pacific Ocean could be used to predict where tornado-causing storms might strike. According to the research team of Laurel McCoy, a graduate student researcher, and Tony Lupo, a meteorology professor and chair of atmospheric science in...

El Nino More Active In 20th Century Than In Previous 700 Years
2013-07-01 07:05:40

Lawrence LeBlond for redOrbit.com - Your Universe Online The El Nino Southern Oscillation (ENSO) is a tropical Pacific Ocean phenomenon that has important consequences for weather around the globe. During years with ENSOs, increased rainfall is seen across the southern US, which has the potential for causing destructive floods. Meanwhile, drought conditions embrace the Western Pacific, increasing the chance of devastating fires throughout Australia. It is also during El Nino years that...

Tree Rings Tell The Tale Of Drought History

Pitt scientists also discover unexpected complexity to the US West's patterns of drought during the Middle Ages Through an exploration of tree rings and oxygen isotopes, researchers at the University of Pittsburgh are now able to better pinpoint the history of droughts in the arid and semiarid areas of the American West. A paper published in the online July 2 issue of the Proceedings of the National Academy of Sciences explores the Medieval Climate Anomaly, a particularly warm period...

Tree ring and oxygen isotope data from the U.S. Pacific Northwest do not provide the same information on past precipitation, but rather than causing a problem, the differing results are a good thing, according to a team of geologists. The researchers are trying to understand the larger spatial patterns and timing of drought in the arid and semiarid areas of the American West. "We generally understand that the Medieval Climate Anomaly, a warm period in much of the northern hemisphere...

El Nino and its partner La Nina, the warm and cold phases in the eastern half of the tropical Pacific, play havoc with climate worldwide. Predicting El Nino events more than several months ahead is now routine, but predicting how it will change in a warming world has been hampered by the short instrumental record. An international team of climate scientists has now shown that annually resolved tree-ring records from North America, particularly from the US Southwest, give a continuous...

Siberia's Lake Baikal, the world's oldest, deepest, and largest freshwater lake, has provided scientists with insight into the ways that climate change affects water temperature, which in turn affects life in the lake. The study was published in the journal PLoS ONE on Feb. 16. "Lake Baikal has the greatest biodiversity of any lake in the world," explained co-author Stephanie Hampton, deputy director of UC Santa Barbara's National Center for Ecological Analysis & Synthesis (NCEAS). "And,...

SACRAMENTO, Calif., Dec. 14, 2010 /PRNewswire/ -- The Delta Stewardship Council (DSC) will continue to make progress on the Delta Plan this week by reviewing two new White Papers and a Delta Plan proposed draft outline. The Delta Plan will guide state and local agencies to help achieve the coequal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. White Papers are being prepared to describe historic and existing...

Researchers looking at corals in the western tropical Pacific Ocean have found records linking a profound shift in the depth of the division between warm surface water and colder, deeper water traceable to recent global warming.The finding is the first real evidence supporting what climate modelers have been predicting as the effects of global climate change on the subsurface ocean circulation.The report by researchers from Ohio State University and the University of Toronto was published in...

'A recipe for a perfect drought' The convergence in the coming year of three cyclical conditions affecting ocean temperatures and weather is likely to create unprecedented challenges for states that depend on water from the Colorado River, a new UCLA study suggests. "If I were concocting a recipe for a perfect drought, this would be it," said Glen MacDonald, co-author of the study and director of UCLA's Institute of the Environment and Sustainability. Along with a former graduate...

DEERFIELD, Ill., Sept. 7 /PRNewswire/ -- While many climate experts and environmentalists explore the negative effects of global warming, a new study reveals a positive outcome of the warming of the planet: the potential elimination of the plague. Global warming affects temperatures and precipitation regimes that play a pivotal role in the lives of rodents and fleas; rodents and fleas are responsible for maintenance and spread of plague to human populations. Plague can be fatal if the...
