British scientists say they've found a "chemical equator" that divides Northern Hemisphere polluted air from the mostly uncontaminated Southern Hemisphere.
Scientists around the world are using everything from weather balloons to airplanes and even a yellow submarine to solve the intriguing climate conundrum of Peru, which is getting colder as the rest of the planet heats up.
By Bill Scanlon Wheat is withering, hungry cattle are being sold to Kansas, and lawns and fields are browning as Colorado endures record heat and dry conditions that may be the continuation of a 10-year pattern.
The next time you have to raise your umbrella against torrents of cold winter rain, you may have a remote weather phenomenon to thank that many may know by name as El NiÃ±o, but may not well understand.
Forecasters warned Tuesday that a La Nina weather pattern - the nasty flip side of El Nino - is brewing, bringing with it the threat of more hurricanes for the Atlantic.
A weak El Nino under way in the Pacific Ocean should contribute to a mild winter for much of the United States, the National Weather Service reported Tuesday.
An important wind circulation pattern over the Pacific Ocean has begun to weaken because of global warming caused by human activity, something that could alter climate and the marine food chain in the region, new research suggests.
GENEVA (Reuters) - Cool sea surface temperatures in the central and eastern Pacific point to a La Nina phenomenon, but it is too early to predict the impact on global weather, the World Meteorological Organization (WMO) said on Friday. The phenomenon was also not expected to last long, the U.N.
By Rosemarie Francisco MANILA (Reuters) - The Philippines has warned farmers and ordered government agencies to prepare for heavy rains and flash floods from a stormy La Nina weather pattern that has already killed 16 in the country's southeastern provinces.
A study by NASA and university scientists is shedding new light on a mysterious, cyclical wave in Earth's atmosphere that at times profoundly affects our planet's weather and climate.
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...
