Latest El Niño-Southern Oscillation Stories
How does mathematics improve our understanding of weather and climate?
Scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation (ENSO), a Pacific Ocean climate cycle that affects weather patterns worldwide, by examining a set of 7,000-year-old coral fossils.
World Meteorological Association (WMO) reports on a global warming trend experienced during the first 10 months of 2102.
The Walker circulation determines much of the tropical Indo-Pacific climate and has a global impact as seen in the floods and droughts spawned by the El Niño-Southern Oscillation.
In the wake of Hurricane Sandy, climatologists from the University of California at Merced are warning that the West Coast could be in line for a superstorm of its own.
Two different competing climatic effects -- increasing temperatures and changes in atmospheric water transport -- will determine how much (or how little) rainfall the South Pacific islands will receive in the future.
El Nino Event “Failure to Launch” Andover, MA (PRWEB) October 23, 2012 WSI (Weather Services International)
Scientists expect global warming to intensify extreme precipitation, but the rate of intensification in the tropics remains unclear. A new study from MIT, published online this week in Nature Geoscience, gives an estimate based on model simulations and observations.
South Pacific countries will experience more extreme floods and droughts, in response to increasing greenhouse gas emissions.
A busier than average start to the season has NOAA's Climate Prediction Center revising their predictions and warning coastal residents to prepare for potential storms.
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...
