Latest Tropical meteorology Stories
On Wednesday, the World Meteorological Organization said that an El Nino current now in the Pacific Ocean would last until 2010, promising unpredictable disruption in weather patterns around the world.
Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in Boulder, Colo
On Thursday government scientists said that periodic warming of water in the tropic Pacific Ocean, also known as El Nino, has returned, which will affect weather around the globe.
The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years, probably because of a warmer world, according to research published in the July issue of Nature Geoscience.
The El Nino Southern Oscillation (ENSO) phenomenon has been shown to have a significant effect on the results of the Ashes cricket series.
Chronology of growth rings from tropical Australia compiled for the first time.
A 1918 El Nino event may have been much more intense than experts previously considered, according to new research.
The US Climate Prediction Center (CPC) said on Thursday that La Nina weather will remain until spring of this year, but should gradually weaken during that time.
A new study by researchers at the University of New South Wales (UNSW) finds that warming and cooling cycles in the Indian Ocean may be responsible for Australiaâ€™s major droughts.
The Monsoon and Environment Research Group of Peking University submitted a report to Chinese Science Bulletin, recently, showed that regional summer monsoon rainfall in China can be predicted by 1-2 seasons ahead by using the signals of the sea surface temperature anomaly (SSTA) and the subsurface temperature anomaly (STA) in the central equatorial Pacific (CEP).
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...
