NEW YORK -- An important wind circulation pattern over the Pacific Ocean has begun to weaken because of global warming caused by human activity, something that could alter climate and the marine food chain in the region, new research suggests. It's not clear what climate changes might arise in the area or possibly beyond, but the long-term effect might resemble some aspects of an El Nino event, a study author said. El Ninos boost rainfall in the southern United States and western South...

By Deborah Zabarenko WASHINGTON (Reuters) - Climate scientists identified a likely new victim of global warming on Wednesday: the vast looping system of air currents that fuels Pacific trade winds and climate from South America to Indonesia. This could mean more El Nino-like weather patterns in the United States, more rain in the western Pacific and less nourishment for marine life along the Equator and off the South American coast. Known as the Walker Circulation, this system of...

By Christopher Doering WASHINGTON (Reuters) - Drought that has shriveled crops and sparked fires in bone-dry forests will persist and could even worsen across the Southwest and central and southern Plains through at least June, U.S. government forecasters said Thursday. The National Oceanic and Atmospheric Administration said in its spring weather forecast that these regions, which have already seen thousands of acres go up in flames, should brace for a "significant" wildfire season...

GENEVA (Reuters) - Cool sea surface temperatures in the central and eastern Pacific point to a La Nina phenomenon, but it is too early to predict the impact on global weather, the World Meteorological Organization (WMO) said on Friday. The phenomenon was also not expected to last long, the U.N. agency said in a statement. Combined with other oceanic and atmospheric conditions, the temperatures were "consistent with the early stages of a basin-wide La Nina event," the WMO said. But...

WASHINGTON (AP) - Climate change that strengthens the El Nino weather patterns could endanger food supplies for more than 20 million people in Africa, a new study warns. El Nino is a warming of the water in the tropical Pacific Ocean that is associated with changes in air pressure and the movement of high-level winds that can affect weather worldwide. In the past, El Ninos have occurred every four to seven years, but many climate experts worry that continuing global warming will lead to...

By Rosemarie Francisco MANILA (Reuters) - The Philippines has warned farmers and ordered government agencies to prepare for heavy rains and flash floods from a stormy La Nina weather pattern that has already killed 16 in the country's southeastern provinces. Heavy rains, which the weather bureau blamed on a nascent La Nina, have triggered landslides, massive flooding and the evacuation of hundreds of families in the Philippines, which grows rice, corn, coconuts, mangoes and other...

JPL -- A study by NASA and university scientists is shedding new light on a mysterious, cyclical wave in Earth's atmosphere that at times profoundly affects our planet's weather and climate. Using satellite data from the Atmospheric Infrared Sounder (Airs) instrument on NASA's Aqua spacecraft, a research team led by Dr. Duane Waliser of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Dr. Baijun Tian of the California Institute of Technology, also in Pasadena,, set out to study the...

By Christopher Doering WASHINGTON (Reuters) - The return of a La Nina weather pattern this year will likely mean drought in southern and southwestern U.S. states, government forecasters said on Thursday, adding it was too early to tell if La Nina would also lead to more Atlantic hurricanes in 2006. La Nina is an unusual cooling of Pacific Ocean surface temperatures, which can trigger widespread changes in weather around the world. Forecasters with the National Oceanic and...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...

ENSO Impacts on Baltimore Tornado Count
2012-12-29 12:12:03

ENSO has an impact on the severe weather across the United States.  As we look at the above graph we see that the area of Baltimore is impacted by ENSO and its tornado count. The stats are for the described years to the left of each bar. During a La-Nina the tornado count picks up for the region; within 50 miles of the city up to 9 tornadoes occurred during the 2000 event. The 2010 EL-Nino set into the region and the tornado count dropped to around 4 tornadoes within 50 miles of the...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...

ENSO Effects On Ocean Waters
2012-09-14 11:46:45

The above graph highlights how the ENSO has an impact on water temps. Northern Gulf of Mexico during EL-Nino: The first part of March during this EL-Nino cycle saw water temps in the 56-60F range, while the 8-14th saw water temps warm to the 60-64F range. By the third week of March temps had maintained 60-64F. The last week of March the temps dropped back to around 56-60F. Northern Gulf of Mexico during LA-Nina: The first week of March saw water temps approach the 70-72F range, by the...

Winds Impacted By The Cycles Of ENSO
2012-09-03 16:44:02

When it comes to wind, more and more people are turning to it as alternative option for electricity. One has to wonder what kind of impacts would be created by the different cycles of ENSO. The above graph has been done for Boston MA. The month of choice was to run it for March of all three cycles. Normal Cycle: (When we are in between EL-Nino and La-Nina) winds averaged around 0-5mph 9% of the month of March. While 6-10mph average winds occurred more often with 35%. And then winds in the...
