  An Update from NASA's Sea Level Sentinels: Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. While the rise of the global ocean has been remarkably steady for most of...

In three decades of recording Arctic Ocean sea ice, the National Oceanographic and Atmospheric Administration (NOAA) on Monday reported that in July 2011 the sea ice hit its lowest monthly recorded level. Sea ice in the Arctic covered an average 3 million square miles during July, the lowest measurement for that month since the NOAA started keeping such records in 1979. The July 2011 figure is 81,000 square miles smaller than 2007's July record low and about 22 percent below the average for...

A new study published in the Friday edition of the journal Science has found that East Africa has been affected by the ENSO phenomenon (El Niño Southern Oscillation) known as El Niño/La Niña for more than 20,000 years. The work, which was completed by scientists from Germany, Switzerland, the US, the Netherlands, and Belgium, studied Lake Challa, a crater lake near Mt. Kilimanjaro. According to a press release from the University...

A Montana State University researcher who analyzed 100 years of data has found a significant link between extreme Montana weather and the ocean temperatures near Peru. Montanans who want to know what to expect from the weather should look to the Pacific Ocean in the fall or maybe find a way to chat with some Peruvian fishermen, according to Joseph Caprio, professor emeritus in MSU's Department of Land Resources and Environmental Sciences and former Montana State Climatologist. If the average...

According to the National Oceanic and Atmospheric Administration (NOAA), coastal communities along the U.S. East Coast could be at risk to higher sea levels and more destructive storm surges in future El Nino years. NOAA's new study examined water levels and storm surge events during the "cool season" of October to April for the past five decades at four sites. The study found that strong El Nino years caused the East Cost to have three times the average number of storm surge events. ...

The U.N. weather agency said on Monday that the La Nina weather pattern is easing and there are no signs that suggest a resurgence in the coming months. "The La Nina episode, which caused disastrously wet conditions in certain regions and drought in others, is coming to an end," the World Meteorological Organization (WMO) said in a statement to the AFP news agency. According to the WMO report, the weather pattern, which is being blamed for extremely heavy downpours in Australia, Southeast...

April 2011 was an extreme climate month of historic flooding, a record-breaking tornado outbreak and devastating wildfire activities in much of the United States, scientists at NOAA's National Climatic Data Center (NCDD) say. The monthly analysis provided by NOAA, based on records that date back to 1895, showed that the average U.S. temperature in April was 52.9 degrees F, which is 0.9 degrees F above the long-term average (1901-200); and the precipitation was 0.7 inches above the long-term...

NASA's Tropical Rainfall Measuring Mission satellite has been keeping track of the drenching rainfall that has been occurring in the central U.S. this springtime, and a newly created rain map from that data from April 4 to May 4, 2011 shows those soaked areas. A combination of heavy rains and a large snow melt has put parts of the central U.S. at risk for record flooding this spring with several locations along the Mississippi already at or near record levels. One likely culprit is La...

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...

Millions of Americans are dealing with an above average year for storms as an atmospheric phenomenon continues to churn in the eastern Pacific Ocean with little chance of dissipating soon. The current winter storm -- being called the blizzard of 2011 -- is possibly a product of the La Nina phenomenon that has been affecting the tropical Pacific Ocean for the past several months, the same phenomenon that is being blamed for the devastating floods and storms battering eastern Australia. Here...

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

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...
