FRISCO —It took a few trips during the early morning hours, but I finaly figured out the light along Tenmile Creek, near Copper Mountain, Colorado — yet another sweet spot for photography. Visit our Fine Art America online gallery for more Summit County landscape and nature images. (more…)

Temps run above average, especially nighttime lows
Winter took hold of Summit County in November.
By Bob Berwyn
FRISCO — After going gangbusters in October, snowfall tapered off to near average in November, with about 20.1 inches if the white stuff piling up in downtown Breckenridge, where observer Rick Bly tracks daily totals for the National Weather Service. For the weather year to-date (starting Oct. 1), Bly has measured 40.6 inches of snow, about 19 percent above average.
Looking ahead, thee long-term historic average for December is 22.4 inches, and the snowiest December on record for Breckenridge wasn’t all that long ago — in 1983, Bly said he tallied 86.9 inches of snow, which remains the all-time record going back more than 100 years. (more…)

The frozen fog of Dillon Reservoir
FRISCO —Right on schedule, winter kicked in with a vengeance in early December, bringing snow, and the first outbreak of sub-zero temps. For a few days each year, before the reservoir freezes over, this means there’s a magical time when the trees along the shoreline are coated with a thick layer of what is, essentially, frozen fog. As chilly as it is to operate camera controls, I always try to make one or two photographic forays around the Dam Road and the Dillon Marina area, where the frost always seems to be thickest. Here’s the first frosty set from this year. Visit our Fine Art America online gallery for more Summit County landscape and nature images. (more…)

Early winter in Colorado
November 2012 brought one of the most spectacular displays of stacked wave and lenticular clouds that I’ve ever seen.
FRISCO —November may not be the sexiest month — no wildflowers, the aspen leaves are long gone and there’s usually not quite enough snow for real wintry scenes. But I’ve learned in the last few years that it’s a month that can bring incredible displays of color in the sky, dramatic cloudscapes and wonderful frost and ice scenes. One of these shots will be featured in out 2014 Summit Voice calendar. What’s your favorite? (more…)

Cold, stormy weather is headed for Colorado.
Polar air mass to bring subzero readings
By Summit Voice
FRISCO — Coloradans should prepare for some of the coldest weather in recent memory, weather forecasters say. The Arctic air expected to begin arriving Tuesday could bring some of the coldest readings since a memorable February 2011 cold snap, when temperatures in the high country dipped to 20 degrees below zero.

2013 brought record levels of dust to Colorado’s mountains
More frequent desert dust storms dropping pollution on the Rocky Mountain snowpack is one of the climate change impacts affecting the Colorado high country.
By Bob Berwyn
FRISCO — Dust storms that darken the Rocky Mountain snowpack and speed snowmelt are becoming more extreme, according to new research. Particularly heavy dust-on-snow events can speed the melt-out of the snowpack by a full six weeks, all other factors being equal, said Jeffrey Deems, a researcher with the Western Water Assessment and the National Snow and Ice Data Center.
In 2006 we were impressed at how much dust there was. Then 2009 turned up, and 2010, and 2013 was the dustiest year we’ve recorded in the San Juans,” Deems said, explaining that the latest study, put together by researchers with NOAA’s Cooperative Institute for Research in Environmental Sciences was aimed at updating previous work with data from those heavy dust years.
Last spring, on April 8, a single 16-hour dust storm dropped more dust on the San Juans than the annual totals in any previous winter since scientists started taking detailed measurements, said Chris Landry, director of the Center for Snow and Avalanche Studies in Silverton, which tracks the dust-on-snow events via a network of observation sites.

CAIC forecasters highlight ‘very real and rapidly increasing avalanche danger’
By Summit Voice
FRISCO — A developing winter storm has prompted the season’s first avalanche warning in the Colorado high county. With up to 12 inches of snow expected across the higher terrain, forecasters with the Colorado Avalanche Information Center say extra caution is required for backcountry travel this weekend.
“Don’t let the fresh snow blind you to the very real and rapidly increasing avalanche danger,” the CAIC posted on its website. The heaviest snow is expected Saturday afternoon and Saturday night and the thin and brittle early season snowpack likely won’t be able to support the fresh snow, especially in wind-loaded areas.

Climate action needed now to protect winter for future generations.
School outreach, social media campaign aims to empower youth
By Summit Voice
FRISCO — Ski and snowboard pros like Gretchen Bleiler and Jeremy Jones don’t need the IPCC to tell them that climate change is already having big impacts — they’ve been experiencing the changes first-hand for years. And as part of the Protect Our Winters campaign, they’ve taken their action-oriented message from the halls of Congress to the auditoriums at schools around the country. This month, POW relaunched its “Hot Planet/Cool Athletes” program to bring that perspective into classrooms.
The goal is to explain climate change in an engaging way, and to inspire and empower students to become involved in the movement to protect the winter sports and winter mountain environment. Sponsored by The North Face, and in association with Clif Bar, Mountain Equipment Co-Op and Teton Gravity Research, the program has already been presented to more than 20,000 students at 41 schools nationwide since 2011.

Mountain high …
Gore Range at sunrise.
FRISCO —For a change, I dipped back into the archives to grab a few of my favorite mountain shots from last winter, as much to inspire myself as anything else. Usually when I finish a photo session, there are a couple of things nagging in the back of my mind. I’m not the most methodical person, so often I find myself thinking, “Oh, I should have adjusted by ISO — that way I could have stopped down the lens for better depth of field. If I have time, I’m getting better at shooting a full range of exposures to edit. It’s amazing how much different a few hundredths of a second or one F-stop can make. Pulling last year’s pictures is a good way to remind myself of the things I wanted to try in the quest for better images! (more…)

Shifts in precipitation patterns would have big consequences for agriculture, forests and municipal water supplies
Research suggests that deforestation will likely produce a weather cycle over the Amazon consisting of abnormally dry air in the sun-scorched northern Amazon around the equator weighted by wetter air in the cooler south (left). The Princeton-led researchers found that the Amazon pattern would be subject to meandering high-altitude winds known as Rossby waves that move east or west across the planet (center). The Rossby waves would move the dry end of the Amazon pattern directly over the western United States from December to February, while the pattern’s rainy portion would be over the Pacific Ocean south of Mexico (right).

FRISCO — Continued deforestation in the Amazon region could have significant impacts on the weather in North America, according to Princeton researchers, who used fine-grained climate models to simulate how precipitation patterns could shift in the future.
Their findings suggest that total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States — specifically, 20 percent less rain for the coastal Northwest and a 50 percent reduction in the Sierra Nevada snowpack, a crucial source of water for cities and farms in California.
“The big point is that Amazon deforestation will not only affect the Amazon — it will not be contained. It will hit the atmosphere and the atmosphere will carry those responses,” said lead author David Medvigy, an assistant professor of geosciences at Princeton. (more…)
