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...

When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by the National Center for Atmospheric Research (NCAR) shows that when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably. Unlike other continents, the soils and topography of Australia prevent almost all of its precipitation from running off into the...

How Cold, Deep Ocean Waters Influence Sea Surface Temperatures
2013-07-26 06:04:28

Brett Smith for redOrbit.com - Your Universe Online Newly published research from Oregon State University has revealed new details on the forces behind El Nino and could lead to more refined predictions for global warming. According to their report in the journal Nature, OSU scientists have used new measurements of ocean mixing to record the first multi-year data set that will allow for a comprehensive analysis of how cold, deep ocean waters can influence sea surface temperatures on a...

El Nino More Active In 20th Century Than In Previous 700 Years
2013-07-01 07:05:40

Lawrence LeBlond for redOrbit.com - Your Universe Online The El Nino Southern Oscillation (ENSO) is a tropical Pacific Ocean phenomenon that has important consequences for weather around the globe. During years with ENSOs, increased rainfall is seen across the southern US, which has the potential for causing destructive floods. Meanwhile, drought conditions embrace the Western Pacific, increasing the chance of devastating fires throughout Australia. It is also during El Nino years that...

Atmospheric Circulation Patterns In Australia Disrupted By Climate Tug Of War
2013-06-26 14:03:02

CSIRO Further evidence of climate change shifting atmospheric circulation in the southern Australian-New Zealand region has been identified in a new study. The study, in the Nature journal Scientific Reports, demonstrates that mid-latitude high pressure zones (30oS-45oS) are being pushed further into the Southern Ocean by rising global temperatures associated with greenhouse warming. This is despite more frequent occurrences of strong El Niños in recent decades, which should have drawn...

El Nino Has A New Rhythm
2013-05-27 04:59:39

redOrbit Staff & Wire Reports - Your Universe Online Climate experts from the University of Hawai'i at Manoa Meteorology Department and International Pacific Research Center have reportedly discovered why the weather phenomenon known as El Nino typically peaks around Christmas and ends sometime between the months of February and April. As it turns out according to researchers, "An unusual wind pattern that straddles the equatorial Pacific during strong El Nino events and swings back...

Strong Correlation Between Asian Summer Monsoon And The Climate Pattern That Preceded It
2013-04-24 10:13:28

University of California, San Diego For much of Asia, the pace of life is tuned to rhythms of monsoons. The summer rainy season is especially important for securing the water and food supplies for more than a billion people. Its variations can mean the difference between drought and flood. Now a Scripps Institution of Oceanography, UC San Diego-led study reports on a crucial connection that could drastically improve the ability of forecasters to reliably predict the monsoon a few months...

Fluffy Antarctic Snow Provides New Insights On Climate Cycles
2013-02-26 10:35:56

April Flowers for redOrbit.com - Your Universe Online A team of scientists, led by researchers at the University of California, San Diego, has found particles from the upper atmosphere trapped in a deep pile of Antarctic snow that hold clear chemical traces of global meteorological events. The study was published in the early online edition of the Proceedings of the National Academy of Sciences and suggests anomalies in oxygen found in sulfate particles coincide with several episodes of...

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...
