Latest Tropical meteorology Stories
California residents plagued by drought just got some good news from the National Oceanic and Atmospheric Administration: El Niño is coming – maybe.
During very strong El Niño events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa.
A new analysis of rain patterns has revealed that extreme El Niño events, such as the 1983 heat wave that caused Australia’s Ash Wednesday bushfires, will double as the planet warms in the years ahead.
Recent NASA research tying California weather to large-scale atmospheric patterns contributed to the newly issued experimental Winter Outlook Forecast for Water Year 2014 by the California Department of Water Resources (DWR).
In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report that the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires.
Scientists have developed a new approach to analyzing paleo-climate reconstructions of the El Niño Southern Oscillation (ENSO) phenomenon. Their findings resolve disagreements and reveals that activity during the 20th century has been unusually high compared to the past 600 years.
New research shows how rising temperatures could affect the future of the global weather pattern known as El Nino.
The Christmas Island red crab makes a hard and amazingly-precise journey every year from its earthen burrow to the shores of the Indian Ocean for weeks of mating and egg-laying. But new research suggests this migratory journey may be delayed in drier seasons.
One tornado can be damaging enough; severe weather systems that spawn hundreds of deadly tornadoes in super-outbreaks pose special challenges to the scientific and emergency management communities.
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.
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...
