Latest Tropical meteorology Stories
A Montana State University researcher who analyzed 100 years of data has found a significant link between extreme Montana weather and the ocean temperatures near Peru.
According to NOAA, coastal communities along the US East Coast could be at risk to higher sea levels and more destructive storm surges in future El Nino years.
The UN weather agency said on Monday that the La Nina weather pattern is easing and there are no signs that suggest a resurgence in the coming months.
A sediment core from a South American lake revealed a steady, sharp drop in crucial monsoon rainfall since 1900, leading to the driest conditions in 1,000 years as of 2007 and threatening tropical populations with water shortages.
NASA's Tropical Rainfall Measuring Mission satellite has been keeping track of the drenching rainfall that has been occurring in the central US this springtime, and a newly created rain map from that data from April 4 to May 4, 2011 shows those soaked areas.
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.
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 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.
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."
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.
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...
