Latest Tropical meteorology Stories
Itâ€™s hot out right now, but new research from North Carolina State University will help us know what to expect when the weather turns cold.
NOAA announced Thursday that last month was the hottest June ever recorded on Earth.
La Nina is likely to cool the tropical Pacific waters in the months ahead, causing stronger monsoons throughout Asia and eastern Australia.
On Tuesday, weather experts said that El Nino has peaked and would probably disappear by mid-year.
Despite nearly two-thirds of the United States experiencing colder-than-normal seasonal temperatures, the 2009-2010 winter season was the fifth warmest on record worldwide.
Researchers are tracking Indian Ocean climate patterns with the possibility that they will improve early-warning systems for the El Nino phenomenon, which could save countless lives and billions of dollars lost each year to the severe weather it causes.
Large-scale weather patterns which occur in various locations around the Earth, from the El NiÃ±o-Southern Oscillation (ENSO) in the tropics to the high latitude Arctic Oscillation (AO) play a significant part in controlling the weather on a seasonal time scale.
Distinct long-term variations of wet and dry phases in the tropics of East Africa.
Since May 2009, the tropical Pacific Ocean has switched from a cool pattern of ocean circulation known as La NiÃ±a to her warmer sibling, El NiÃ±o.
Scientists say the eastern Pacific El Nino, which can shield the United States from severe hurricane seasons, may be reduced in effectiveness by global warming. There are two El Ninos, or flavors of El Nino, said Ben Kirtman, a professor at the University of Miami's Rosentstiel School of Marine and Atmospheric Science.
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...
