Latest Tropical meteorology Stories
Based on satellite data, experts have found near-normal sea-surface height conditions across the equatorial Pacific Ocean, indicative of a so called “La Nada” event.
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.
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.
The El Nino Southern Oscillation (ENSO) is a tropical Pacific Ocean phenomenon that has important consequences for weather around the globe.
Further evidence of climate change shifting atmospheric circulation in the southern Australian-New Zealand region has been identified in a new study.
Climate experts 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.
For much of Asia, the pace of life is tuned to rhythms of monsoons.
How does mathematics improve our understanding of weather and climate?
Scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation (ENSO), a Pacific Ocean climate cycle that affects weather patterns worldwide, by examining a set of 7,000-year-old coral fossils.
World Meteorological Association (WMO) reports on a global warming trend experienced during the first 10 months of 2102.
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...
