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...

The La Nina weather pattern circulating through the eastern-central Pacific Ocean, which is behind the floods and extreme conditions in Australia, Asia, Africa and South America is one of the strongest ever and could last for four more months, according to the UN weather agency. "In atmospheric terms it has to be termed one of the strongest ever La Nina episodes," Rupa Kumar Kolli, head of world climate services at the UN's World Meteorological Organization (WMO), told the AFP news agency....

New NASA satellite data indicate the current La Niña event in the eastern Pacific has remained strong during November and December 2010. A new Ocean Surface Topography Mission (OSTM)/Jason-2 satellite image of the Pacific Ocean that averaged 10 days of data was just released from NASA. The image, centered on Dec. 26, 2010, was created at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. "The solid record of La Niña strength only goes back about...

Scientists stated on Wednesday that global climate changes are a likely trigger of the recent intense monsoon rains that have resulted in the deadly flooding of the Australian state of Queensland. The Queensland floods have killed 16 people since the downpours started in December, inundating towns, crippling the coal mining industry, and now swamping the state's main city of Brisbane. One of the strongest La Nina patterns ever recorded is being blamed for the rain.  La Nina is a cooling...

A doubling of abnormally wet or dry summer weather in the southeastern United States in recent decades has come from an intensification of the summertime North Atlantic Subtropical High (NASH), or "Bermuda High." And that intensification appears to be coming from global warming, according to a new analysis by a Duke University-led team of climate scientists. The NASH is an area of high pressure that forms each summer near Bermuda, where its powerful surface center helps steer Atlantic...

While it's still hotly debated among scientists whether climate change causes a shift from the traditional form of El Nino to one known as El Nino Modoki, online in the journal Nature Geoscience, scientists now say that El Nino Modoki affects long-term changes in currents in the North Pacific Ocean. El Nino is a periodic warming in the eastern tropical Pacific that occurs along the coast of South America. Recently, scientists have noticed that El Nino warming is stronger in the Central...

The U.N. weather agency said on Monday that the disruptive La Nina weather pattern in the Pacific basin should strengthen over the next four to six months, bringing on stronger monsoons and more hurricanes. Rupa Kumar, World Meteorological Organization climate services chief, said a "moderate to strong" La Nina was now well established. Kumar Kolli told reporters that forecasts showed "rather a strengthening of this La Nina episode for the next four to six months." La Nina is the opposite...

Year-long study suggests local Chinese officials and 'green' paper company flouted farmers' rights in plan for 120,000-hectare plantation A new study released today in Washington, DC and Beijing suggests that one of the world's largest and "greenest" paper companies, in concert with local officials and other middlemen, used illegal means to gain control over thousands of hectares of Chinese forestlands, with a goal of acquiring 120 thousand hectares for a eucalyptus plantation in the Guangxi...

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...
