LONDON -- A resurgent El Nino and persistently high levels of greenhouse gases are likely to make 2007 the world's hottest year ever recorded, British climate scientists said Thursday. Britain's Meteorological Office said there was a 60 percent probability that 2007 would break the record set by 1998, which was 1.20 degrees over the long-term average. "This new information represents another warning that climate change is happening around the world," the office said. The reason for the...

By Lehodey, P; Alheit, J; Barange, M; Baumgartner, T; Et al ABSTRACT Fish population variability and fisheries activities are closely linked to weather and climate dynamics. While weather at sea directly affects fishing, environmental variability determines the distribution, migration, and abundance of fish. Fishery science grew up during the last century by integrating knowledge from oceanography, fish biology, marine ecology, and fish population dynamics, largely focused on the great...

By RANDOLPH E. SCHMID, AP Science Writer WASHINGTON - 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. "The strengthening El Nino event will influence the position and strength of the jet stream over the Pacific Ocean, which in turn will affect winter precipitation and temperature patterns across the country," Michael Halpert, lead forecaster at the NOAA Climate Prediction Center,...

The average temperature of the water near the top of the Earth's oceans has significantly cooled since 2003. New research suggests global warming trends are not always steady in their effects on ocean temperatures. Although the average temperature of the upper oceans has significantly cooled since 2003, the decline is a fraction of the total ocean warming over the previous 48 years. "This research suggests global warming isn't always steady, but happens with occasional 'speed bumps'," said...

WASHINGTON (Reuters) - There is a 50 percent chance a weak El Nino will develop this year, U.S. government weather forecasters said on Thursday, but if the weather abnormality reappears it will be too late to affect the Atlantic hurricane season. The National Oceanic and Atmospheric Administration said a return of El Nino would bring wetter-than-average weather to portions of the Gulf Coast and southeastern U.S., and warmer-than-average temperatures to the West, northern Great...

By Deborah Zabarenko WASHINGTON (Reuters) - La Nina, a Pacific Ocean phenomenon that can help form Atlantic hurricanes, is not expected to be a factor this season, good news after last year's disastrous storm season. La Nina, Spanish for "the girl," refers to a pattern of usually cold surface temperatures in the eastern tropical Pacific. In North America, it has been known to contribute to droughts in the West and to spur hurricanes in the East. That happens because La Nina tends to...

NEW YORK -- 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. It's not clear what climate changes might arise in the area or possibly beyond, but the long-term effect might resemble some aspects of an El Nino event, a study author said. El Ninos boost rainfall in the southern United States and western South...

By Deborah Zabarenko WASHINGTON (Reuters) - Climate scientists identified a likely new victim of global warming on Wednesday: the vast looping system of air currents that fuels Pacific trade winds and climate from South America to Indonesia. This could mean more El Nino-like weather patterns in the United States, more rain in the western Pacific and less nourishment for marine life along the Equator and off the South American coast. Known as the Walker Circulation, this system of...

By Christopher Doering WASHINGTON (Reuters) - Drought that has shriveled crops and sparked fires in bone-dry forests will persist and could even worsen across the Southwest and central and southern Plains through at least June, U.S. government forecasters said Thursday. The National Oceanic and Atmospheric Administration said in its spring weather forecast that these regions, which have already seen thousands of acres go up in flames, should brace for a "significant" wildfire season...

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. agency said in a statement. Combined with other oceanic and atmospheric conditions, the temperatures were "consistent with the early stages of a basin-wide La Nina event," the WMO said. But...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

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 Impacts on Baltimore Tornado Count
2012-12-29 12:12:03

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...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

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...

ENSO Effects On Ocean Waters
2012-09-14 11:46:45

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...

Winds Impacted By The Cycles Of ENSO
2012-09-03 16:44:02

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...
