WASHINGTON -- The return of a La Nina weather pattern this year will likely mean drought in southern and southwestern U.S. states, government forecasters said on Thursday, adding it was too early to tell if La Nina would also lead to more Atlantic hurricanes in 2006. La Nina is an unusual cooling of Pacific Ocean surface temperatures, which can trigger widespread changes in weather around the world. Forecasters with the National Oceanic and Atmospheric Administration said La Nina could wreak...

By Deborah Zabarenko WASHINGTON (Reuters) - Last year was the warmest recorded on Earth's surface, and it was unusually hot in the Arctic, U.S. space agency NASA said on Tuesday. All five of the hottest years since modern record-keeping began in the 1890s occurred within the last decade, according to analysis by NASA's Goddard Institute for Space Studies. In descending order, the years with the highest global average annual temperatures were 2005, 1998, 2002, 2003 and 2004, NASA...

WASHINGTON (AP) - A La Nina, a mild cooling of the tropical Pacific Ocean which can affect weather in other areas, is being forecast for spring. La Ninas tend to encourage wet weather in the Pacific Northwest and dry conditions in the south, but National Oceanic and Atmospheric Administration forecasters declined to blame current weather on the phenomena. La Nina is the opposite of the better known El Nino, a Pacific warming. Both occur every few years and can affect weather around the...

JPL -- The joint NASA/Centre National d'Etudes Spatiales Topex/Poseidon oceanography satellite ceased operations after nearly 62,000 orbits of Earth. The spacecraft lost its ability to maneuver, bringing to a close a successful 13-year mission. "Topex/Poseidon revolutionized the study of Earth's oceans, providing the first continuous, global coverage of ocean surface topography and allowing us to see important week-to-week oceanic variations," said Dr. Mary Cleave, associate administrator...

By Christopher Doering WASHINGTON (Reuters) - Americans are bracing for sharply higher heating costs this winter but government forecasters said on Wednesday they could not predict if the energy-dependent U.S. Northeast and Midwest regions will face warmer, colder or typical winter temperatures. The weather forecast is more important than usual with U.S. oil and natural gas production still crippled in the Gulf of Mexico from Hurricanes Katrina and Rita. "This has been one of the...

RIO DE JANEIRO, Brazil -- Drought in the Amazon rain forest, normally one of the world's wettest regions, shows the weather cycle is swinging to one extreme rather than signaling climate change, local meteorologists said Thursday. Water levels on two major Amazon tributaries -- Madeira and Solimoes -- dropped to record- and 38-year lows respectively, creating long delays in river traffic, the main form of regional transport. Dry weather also fanned huge forest fires, notably in the remote...

SAN FRANCISCO -- Marine biologists are seeing mysterious and disturbing things along the Pacific Coast this year: higher water temperatures, plummeting catches of fish, lots of dead birds on the beaches, and perhaps most worrisome, very little plankton - the tiny organisms that are a vital link in the ocean food chain. Is this just one freak year? Or is this global warming? Few scientists are willing to blame global warming, the theory that carbon dioxide and other manmade emissions are...

NASA -- Who would have thought that melting snow cover in the Himalayan Mountains could alter the ocean food chain over a thousand miles away? Well, that's just what's happening, according to a NASA-funded study appearing in this week's Science magazine. The study finds a decline in winter and spring snow cover over Southwest Asia and the Himalayan mountain range is creating the right conditions for more widespread blooms of ocean plants in the Arabian Sea. The decrease in snow cover has...

NASA -- Last year was the fourth warmest year on average for our planet since the late 1800s, according to NASA scientists. To determine if the Earth is warming or cooling, scientists look at average temperatures. To get an "average" temperature, scientists take the warmest and the coolest temperatures in a day, and calculate the temperature that is exactly in the middle of those high and low values. This provides an average temperature for a day. These average temperatures are then...

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...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary.
