El Nino Forecast A Sign Of Relief For Drought-Stricken Californians
2014-03-07 10:37:54

Brett Smith for redOrbit.com - Your Universe Online California residents plagued by drought just got some good news from the National Oceanic and Atmospheric Administration (NOAA): El Niño is coming – maybe. El Niño is a weather-generating phenomenon based on the surface water temperatures off the western coast of South America and NOAA’s long-range forecast has said there is about a 50-50 chance that it will form this summer or fall – potentially bringing wetter weather to the...

What Makes El Niño Taimasa Different From Normal El Niño?
2014-02-20 12:41:02

University of Hawaii During very strong El Niño events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa. The Samoans call the wet stench of coral die-offs arising from the low sea levels "taimasa" (pronounced [kai' ma'sa]). Studying the climate effects of this particular variation of El Niño and how it may change in the future is a team of scientists at the International Pacific Research...

Global Warming Expected To Increase Extreme El Niño Events
2014-01-20 04:34:22

redOrbit Staff & Wire Reports - Your Universe Online A new analysis of rain patterns has revealed that extreme El Niño events, such as the 1983 heat wave that caused Australia’s Ash Wednesday bushfires, will double as the planet warms in the years ahead. “We currently experience an unusually strong El Niño event every 20 years. Our research shows this will double to one event every 10 years,” study co-author Dr. Agus Santoso, a professor at the University of New South Wales...

California Water Planners Listen To NASA Long-Term Forecast
2013-12-10 10:58:41

NASA's Jet Propulsion Laboratory Recent NASA research tying California weather to large-scale atmospheric patterns contributed to the newly issued experimental Winter Outlook Forecast for Water Year 2014 by the California Department of Water Resources (DWR). That forecast, calling for continued dry conditions for the third year in a row, was the first to include discussion of climate research from NASA’s Jet Propulsion Laboratory, Pasadena, Calif. JPL researchers have found a...

Amazon Deforestation Could Mean Droughts For Western United States
2013-11-07 12:22:13

Princeton University In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires. The researchers report in the Journal of Climate that an Amazon stripped bare could mean 20 percent less rain for the coastal...

Recent El Nino Patterns More Active Than In Past 600 Years
2013-10-29 07:31:26

April Flowers for redOrbit.com - Your Universe Online Scientists from the University of New South Wales, the University of Hawaii International Pacific Research Center and the NOAA Geophysical Fluid Dynamics Laboratory have developed a new approach to analyzing paleo-climate reconstructions of the El Niño Southern Oscillation (ENSO) phenomenon. Their findings, published in Climate of the Past, resolve disagreements and reveals that ENSO activity during the 20th century has been unusually...

Global Warning Future Of El Nino
2013-10-14 13:08:34

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the journal Nature says that climate change could have a negative impact on the El Niño-Southern Oscillation (ENSO) weather pattern. El Niño occurs in the Pacific Ocean and is an important part of the world's climate system, and new research shows how rising temperatures could affect the weather pattern in the future. During El Niño, the eastern and tropical Pacific regions of the planet warm up, while...

Lack Of Rain Halts Migration Patterns Of Christmas Island Crabs
2013-10-11 08:56:41

April Flowers for redOrbit.com - Your Universe Online The Christmas Island red crab makes a hard and amazingly-precise journey every year from its earthen burrow to the shores of the Indian Ocean for weeks of mating and egg-laying. The crabs are native to the Australian territories of Christmas Island and the Cocos (Keeling) Islands. When the November rains begin, millions of the crabs begin rolling across the island roads and landscape in crimson waves. Crabs scuttle for two weeks...

One tornado can be damaging enough; severe weather systems that spawn hundreds of deadly tornadoes in super-outbreaks pose special challenges to the scientific and emergency management communities. Now, scientists have identified certain conditions in the Pacific Ocean that may lead to super-outbreaks over the U.S.' tornado alley. Researchers are trying to determine if Trans-Niño years, which mark the onset or ebbing of El Niño and La Niña, are the main culprits behind the deadly...

La Nada Event In Pacific
2013-09-10 15:37:20

Brett Smith for redOrbit.com - Your Universe Online Based on data from one of NASA’s orbiting satellites, experts at the National Weather Service’s Climate Prediction Center have found near-normal sea-surface height conditions across the equatorial Pacific Ocean, indicative of a so called “La Nada” event. The weather experts added that the condition has persisted for 16 months, since spring 2012 and will continue through the spring of 2014. “Without an El Niño or La Niña...

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...
