Scientists believe El Nino may have assisted Magellan's first trip around the world nearly 500 years ago.On Nov. 28, 1520, explorer Ferdinand Magellan encountered fair weather after days of battle through the rough waters south of South America. From there, the calming effects of El Nino may have eased his passage across the Pacific Ocean, researchers speculate.An El Nino creates rising air that changes wind and weather patterns when the Equatorial Pacific become warmer than normal. The...

Boosted by the influence of a larger climate event in the Pacific, one of the strongest La Niñas in many years is slowly weakening but continues to blanket the Pacific Ocean near the equator, as shown by new sea-level height data collected by the U.S.-French Jason oceanographic satellite.This La Niña, which has persisted for the past year, is indicated by the blue area in the center of the image along the equator. Blue indicates lower than normal sea...

UN meteorologists say the cooling effect of the La Nina current in the Pacific will cause global temperatures to drop slightly this year. Michel Jarraud, secretary-general of the World Meteorological Organization, said it was likely that La Nina would continue into the summer. Global temperatures haven't risen since 1998, leaving many to question the climate change theory. However, experts say we are still clearly in a long-term warming trend and new record high temperatures are forecasted...

The next time you have to raise your umbrella against torrents of cold winter rain, you may have a remote weather phenomenon to thank that many may know by name as El Niño, but may not well understand. Researchers now believe that some of the most intense winter storm activity over parts of the United States may be set in motion from changes in the surface waters of far-flung parts of the Pacific Ocean. Siegfried Schubert of NASA's Goddard Space Flight Center in...

WASHINGTON -- "We have met the enemy, and he is us," the comic-strip character Pogo said decades ago. A new analysis of last year's near-record temperatures in the United States suggests he was right. Warming caused by human activity was the biggest factor in the high temperatures recorded in 2006, according to a report by researchers at the National Oceanic and Atmospheric Administration. The analysis, released Tuesday, is being published in the September issue of Geophysical Research...

WASHINGTON -- This winter was the warmest on record worldwide, the government said Thursday in the latest worrisome report focusing on changing climate. The report comes just over a month after the Intergovernmental Panel on Climate Change said global warming is very likely caused by human actions and is so severe it will continue for centuries. The National Oceanic and Atmospheric Administration said the combined land and ocean temperatures for December through February were 1.3 degrees...

Breaking news in recent years has been swamped with stories of extreme weather -- flash floods in East Asia, prolonged drought in Africa, destructive hurricanes like Hurricane Katrina, heavy monsoon rainfall in South Asia, and an historic heat wave in Europe. The effects of these weather crises have been devastating, and their frequency seemingly on the rise. With an understanding that the societal effect of increased rainfall is huge, researchers have had a key question at the center of a...

WASHINGTON -- Forecasters warned Tuesday that a La Nina weather pattern - the nasty flip side of El Nino - is brewing, bringing with it the threat of more hurricanes for the Atlantic. Officials at the National Oceanic and Atmospheric Administration announced the official end of a brief and mild El Nino that started last year. That El Nino was credited with partially shutting down last summer's Atlantic hurricane activity in the midst of what was supposed to be a busy season. "We're seeing a...

Climatologists at the NASA Goddard Institute for Space Studies (GISS) in New York City have found that 2006 was the fifth warmest year in the past century. Other groups that study climate change also rank these years as among the warmest, though the exact rankings vary depending upon details of the analyses. Results differ especially in regions of sparse measurements, where scientists use alternative methods of estimating temperature change. Goddard Institute researchers used temperature...

WASHINGTON - Last year was the warmest on record for the United States, with readings pushed over higher than normal by the unusual and unseasonably warm weather during the last half of December. Preliminary data from the National Climatic Data Center listed the average temperature for the 48 contiguous states last year as 55 degrees Fahrenheit. That's 2.2 degrees warmer than average and 0.07 degree warmer than 1998, the previous warmest year on record. Worldwide, the agency said, it was the...

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...
