From farmers to government officials in charge of efficiently managing Earth's precious water and energy resources, people all over the world rely on accurate short-term climate forecasts on timescales ranging from a few weeks to a few years to make more informed decisions. But today's climate forecast systems have limited ability to operate on such timescales. That's because it's difficult to realistically represent the complex interactions between Earth's ocean, atmosphere and land surface...

UN climate and weather agencies said Wednesday that climate scientists must take an urgent stance on studying the changes in atmospheric currents that have been linked to flooding in Pakistan and wildfires in Russia.Ghassem Asrar, director of the World Climate Research Program, told AFP that changes -- known as blocking episodes -- in the currents can prevent humidity or hot weather from dispersing as it should.Those events can lock heavy rain or heat waves over a particular region, in turn...

It'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. Researchers have developed a new methodology that improves the accuracy of winter precipitation and temperature forecasts. The tool should be valuable for government and utility officials, since it provides key information for use in predicting energy consumption and water availability. "Predicting winter precipitation is extremely useful, because winter...

The U.S. National Oceanic and Atmospheric Administration (NOAA) announced Thursday that last month was the hottest June ever recorded on Earth. According to NOAA's National Climatic Data Center, the combined global land and ocean surface temperature data also showed that the January-June and April-June periods were the warmest on record, which go back as far as 1880. The combined average for global land and ocean temperatures in June was 61.1 degrees Fahrenheit, which are 1.22 degrees...

La Nina is likely to cool the tropical Pacific waters in the months ahead, causing stronger monsoons throughout Asia and eastern Australia, according to an update released Tuesday by the World Meteorological Organization (WMO). These conditions are also likely to promote the development of storms in the tropical Atlantic. "Below average sea temperatures exist beneath the surface of the central and eastern equatorial Pacific, and forecast models continue to predict further decreases in the...

On Tuesday, weather experts said that El Nino has peaked and would probably disappear by mid-year. "The most likely outcome by mid-year 2010 is for the El Nino event to have decayed and near-neutral conditions to be re-established across the tropical Pacific," World Meteorological Organization expert Rupa Koumar Kolli told the AFP news agency. El Nino is a weather anomaly that wrecks havoc around the Pacific and east Africa.  It is an occasional seasonal warming of the central and...

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.  While a large part of the country was colder than usual this past winter, parts of the U.S. did have warmer-than-usual temperatures. Both New England and the Pacific Northwest joined in the global winter warmth. In addition, Maine had its third warmest winter on record, according to the National Oceanic and...

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. Researchers from Japan and France said their new forecast model may predict an El Nino up to 14 months ahead of time, several months earlier than with current models. A paper on the project was published in the journal Nature Geoscience. "It...

Introduction Large-scale weather patterns which occur in various locations around the Earth, from the El Niño-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. Knowing the condition of these atmospheric oscillations in advance would greatly improve long-range weather predictions. Scientists search for clues in the earth's surface conditions such as tropical...

Distinct long-term variations of wet and dry phases in the tropics of East Africa Climatic fluctuations close to the equator show a different pattern to climate change in the Arctic and Antarctic. In the tropics distinct 11500 year fluctuations between wet and dry periods can be clearly identified which do not occur in temperature reconstructions of polar ice cores. The investigations of the climate of the last 25000 years in tropical Africa show that dry phases prevailed during lower solar...

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...
