Image AttachmentWe reported about a week ago (story) that the Climate Prediction Center says that La Nina is gaining strength in the equatorial Pacific, and that the natural, periodic climate change might result in below average rainfall this winter. Since then, NASA has released a new illustration of the emerging La Nina, presented here with an explanation from the space agency:

Continuing a trend that began earlier in the year, La Niña conditions strengthened through the summer of 2010, evidenced by a streak of cool water across the equatorial Pacific Ocean.

Acquired by the Ocean Surface Topography Mission/Jason-2 satellite, this map shows a 10-day average of sea-surface height centered on September 6, 2010. Because water expands with rising temperatures, satellites can use sea-surface height as a proxy for temperature. Areas where the water surface is higher (and therefore warmer) than average are shades of red-brown, and areas where the water surface is lower (cooler) than average are blue. Normal conditions appear in white.

Winter will be colder, longer than last year

Brace yourself, Canada: There will actually be a winter this year.

Preliminary forecasts show the country's in for a longer and more intense winter than last year's uncommonly mild weather, says Dave Phillips, senior climatologist with Environment Canada.

"It could still be warmer than normal… but it won't be a non-winter like last year," which saw the warmest and driest conditions on record, Phillips told earlier this week.

A series of factors contributed to last winter's freakish weather, notably El Nino, a climate pattern from the tropical Pacific Ocean that encourages more powerful westerly winds.

It's still early to make clear predictions for this year – the official forecast comes out Dec. 1 – but current models suggest winter will strike hardest out west, largely due to La Nina, El Nino's counterpart, he added.

La Nina is an extensive cooling of the central and eastern Pacific Ocean caused by the strengthening of easterly trade winds in the tropics. It can trigger generous snowfall from the interior of British Columbia to the Great Lakes region, according to Environment Canada.

Winter Is On Its Way, Snow Descends On Northern Rockies Resorts by Becky Lomax

Vacationers to the Northern Rocky Mountains found drippy wet camping this fall. They may be frowning, but skiers wore grins when early snows hit. Cold air from the north collided with a front from the Pacific Ocean Sept. 16 to bring overnight snow to many of the region's ski resorts.

Ski resort Web cams across the region lit up with snow clinging to trees and blanketing slopes Friday morning. Workers at Castle Mountain, Alberta arrived to find 15 centimeters (6 inches) of snow in the base area. "It's white. It's incredible. Because all the leaves are still on the trees, the snow has much more visual impact," Andrew Rusynyk, assistant general manager, told

Castle Mountain, like most resorts in fall, is racing to finish slope projects before the onslaught of winter. Hazardous fuels reduction crews, thinning for protection of ski runs in the base area, headed off to slog through wet snow with chainsaws, but in chipper moods. "We have a lot of work going on, and they're all smiling, even the guys outside," added Rusynyk. "The snow may even stick around on the top of the mountain."

The Northern Rockies received the brunt of this storm. Other ski resorts with a fresh coat of snow were Marmot Basin, Lake Louise Ski Area, Nakiska, Sunshine Village, Fernie Alpine Resort, and Whitefish Mountain Resort. The snow was not the first of the season. A smattering of western resorts, including Mt. Bachelor, saw fresh snow before the end of August, and Mammoth Mountain picked up its first dusting Sept. 9.

The forecaster at the Southern California Weather Authority has released the winter forecast for the 2010 to 2011 storm season and it will not be a typical La Nina effect with bone dry conditions.

Forecast below courtesy of Southern California Weather Authority

Rain and Snow: The season will have an average season, about half as much as last season's El Nino. The predictions are for just under ten inches in Los Angeles from December to April. There will be dynamic systems in which more thunderstorms are possible in cold cores, however there will not be as many as a typical El Nino year.

Temperatures: Last year there were temperatures that were above normal. This year the predictions are for below normal temperatures and frequent cold blasts into the area.

The major metropolitan areas of the mid-Atlantic that were pummeled with snow last year will get a break this winter, but that doesn't mean there will be no snow to shovel. In contrast, Chicago, Milwaukee and Minneapolis could be in the heaviest snow zone this upcoming winter.

Winter's Worst Cold and Snow

Overall, Chief Long-Range Meteorologist Joe Bastardi is predicting that the worst of winter's cold and snow will be from the Pacific Northwest into the northern Plains and western Great Lakes. That will put cities like Portland and Seattle that escaped with a very nice winter last year, colder and snowier this year. Fargo and Minneapolis to Green Bay will also receive above-normal winter snowfall.

Other cities predicted to receive above-normal winter snowfall include Chicago, Omaha, Minneapolis, Detroit, Cleveland, Seattle and Portland.

Bastardi predicts severe cold will hit Alaska and western and central Canada.

"The Canadian winter will be as harsh as last year's was gentle," Bastardi said.

Scientists: La Niña growing stronger by Pat Brennan

The ocean phenomenon known as La Niña is strengthening, the nation's climate agency says, and that could mean a drier rainy season for Southern California.

Image AttachmentAn update Thursday from the Climate Prediction Center in Maryland says La Niña, a periodic cooling of waters in the equatorial Pacific, strengthened through the month of August, with those waters cooling significantly.

"I would say the trend is toward strengthening, and I see no reason for that to stop," said Ed O'Lenic, a meteorologist at the center which is an arm of the National Oceanic and Atmospheric Administration.

Computer models seem to agree that La Niña will continue through early 2011, but differ on whether it will get stronger; scientists expect the pattern to remain at its present strength or grow stronger, as has typically happened during past La Niña events.

Brace yourself, La Nina threatens wetter, colder NW winter by Glenn Farley

SEATTLE - Remember the winter of 2007/2008? I-5 through Chehalis was under water, clearing snow at Snoqualmie pass was literally wearing out plows and graders. That was our last La Nina, the wetter, colder weather phenomenon that's the opposite of the more common and warmer El Nino. At least that's what it all means for the Pacific Northwest.

La Nina occurs when the surface water near the equator tends to be cooler than normal in the eastern Pacific Ocean. El Nino is the opposite, as warm water pushes up against central and south America. While the engine of these weather effects seems a long way off, their effects are global.

On Thursday, NOAA's Climate prediction Center issued a new advisory about La Nina, saying it strengthened during August.

"Nearly all models predict La Nina to continue at least through early 2011," the report's authors said. Adding, "La Nina will begin to exert an increasing influence on the weather and climate of the United States. These impacts include an enhanced chance of above-average precipitation in the Pacific Northwest."

Old Farmer's Almanac: Global cooling to continue by Russell Contreras

DUBLIN, N.H. -- Most of the country will see a colder-than-usual winter while summer and spring will be relatively cool and dry, according to the time-honored, complex calculations of the "Old Farmer's Almanac."

The 2011 issue of the almanac, which claims to be the nation's oldest continuously published periodical, was released Tuesday. It predicts that in the coming months, the Earth will continue to see a "gradual cooling of the atmosphere ... offset by any warming caused by increased greenhouse gases."

The "Old Farmer's Almanac" also is forecasting a weak La Nina - a climate phenomenon marked by an unusual cooling of the sea surface in the tropical Pacific Ocean.

Janice Stillman, editor of the almanac, said that means much of the eastern half of the United States will experience lower-than-normal temperatures with less snow while Mid-Atlantic states will see more snowfall than usual. The West will see a mild winter with average precipitation, she said.

Meanwhile, the South will experience a cold and wet summer and the Rockies should see a mild and dry winter, according to the New Hampshire-based "Old Farmer's Almanac."

"It'll be cold. There will be no mistaking winter," Stillman said. "But it may be a little shorter or we may see some small warm spells in places like the East Coast."

Meteorologist expects monster La Nina - Drastic cooling

Southern Hemisphere sea ice now approaching record high levels

25 Aug 10 - Although Northern Hemisphere LAND MASSES had their hottest May-July on record, says meteorologist Joe Bastardi, the globe as a whole did not.

The warmth ON LAND is a by-product of the years of warm Pacific Decadal Oscillation (PDO) and El Nino, says Bastardi. The land kept warming after the water began to cool. It's "sort of like high tide in back bay occurring after it had occurred on the beach (oceans) and the tide is about to go out."

"If one uses common sense, one would understand that land masses with warm water next to them for years would warm greatly," says Bastardi.

Southern Hemisphere sea ice now approaching record high levels

However, "the expansion of the Southern Hemisphere sea ice, now approaching record high levels, ought to tell you something about the oceans immediately around the sea ice," says Bastardi. This large mass of water is cooling and has cooled most dramatically in the area where it is warmest (the tropical pacific).

The Pacific Northwest had a less-than-stellar winter in terms of skiing last year as seen in the Vancouver Olympics.

A La Nina weather pattern this year, however, could mean stormier weather for the 2010-2011 season.

It can be difficult to forecast just how much more moisture a wetter-than-normal winter will bring, Expert Senior Meteorologist and West Coast resident Clark said. For the Pacific Northwest, though, Clark is predicting that precipitation will be "normal to well-above normal." He described above-normal precipitation as 20 percent or more that is typically received in the region.
