Latest El Niño-Southern Oscillation Stories
Breaking news in recent years has been swamped with stories of extreme weather. Are rain-producing weather events increasing worldwide, and if so, what is the relationship, if any, between their growth and climate change?
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.
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.
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.
A resurgent El Nino and persistently high levels of greenhouse gases are likely to make 2007 the world's hottest year ever recorded, British climate scientists said Thursday.
By Lehodey, P; Alheit, J; Barange, M; Baumgartner, T; Et al ABSTRACT Fish population variability and fisheries activities are closely linked to weather and climate dynamics.
A weak El Nino under way in the Pacific Ocean should contribute to a mild winter for much of the United States, the National Weather Service reported Tuesday.
The average temperature of the water near the top of the Earth's oceans has significantly cooled since 2003. New research suggests global warming trends are not always steady in their effects on ocean temperatures.
WASHINGTON (Reuters) - There is a 50 percent chance a weak El Nino will develop this year, U.S. government weather forecasters said on Thursday, but if the weather abnormality reappears it will be too late to affect the Atlantic hurricane season.
By Deborah Zabarenko WASHINGTON (Reuters) - La Nina, a Pacific Ocean phenomenon that can help form Atlantic hurricanes, is not expected to be a factor this season, good news after last year's disastrous storm season.
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 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...
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...
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...
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...
