Mountains play key role in lake
SALT LAKE CITY Those notorious lake effect snowstorms that delight winter revelers in the 4-chlorodehydromethyltestosterone Salt Lake Valley could appropriately be called mountain effect storms.
A study published Tuesday in the American Meteorological Society Journal's Monthly Weather Review shows the interplay of winds and mountains particularly the Wasatch Front and Oquirrh ranges are critical actors that enhance these events.
Steenburgh is a professor of atmospheric sciences at the University of Utah who partnered with a doctoral student, Trevor Alcott, who now works at the National Weather Service in Salt Lake City.
The lake effect occurs when a cold mass of air moves over a large body of warmer water, picking up moisture and heat to make the air mass rise and cool, ultimately dumping snow downwind. Steenburgh said it already was known that lake effect snowfall increases as the moist air rises over mountains. But the latest study shows something new and different: Mountains sometimes are essential to triggering the lake effect Anadrol 50 For Sale With Credit Card over the lakes themselves.
"You take the mountains out and take the lake out, you get rid of any snow at all," he said.
Weather forecast models now fail to adequately include the Wasatch Range, which runs north to south directly east of the Great Salt Lake and the Ogden Salt Lake City Provo metropolitan area. Forecast models also don include northern Anadrol Keifei mountains along the Nevada Idaho Utah border, located northwest and north of the Great Salt Lake, Salt Lake metropolitan area and Wasatch Range.
may be one of the reasons we struggle in forecasting lake effect storms in Utah major cities, he said.
This particular study looked at the moderate lake effect snowstorm that hit metropolitan Salt Lake City and the Wasatch Range on Oct. 26 27, 2010.
While "Hgh Jintropin Avis" some cities in Anavar Zmrc the Salt Lake Valley had no snow, the Alta Ski Area got pounded with 13 inches.
Research showed three distinct elements at work because of "Anabola Steroider Norge Lagligt" the interaction between the Great Salt Lake and the surrounding mountains:
Winds become warmer as it moves over mountains and flows south and southeast toward the Great Salt Lake, moderating the strength of a lake effect storm.
Northern mountain ranges deflect cold air masses "Oxandrolone Powder India" as they converge over the Great Salt Lake and the air picks up heat and moisture from the lake. But the convergence of air from the northeast and west makes it rise and cool, producing lake effect snow Buy Jintropin bands over the lake.
The Wasatch and Oquirrh ranges that form the boundaries of the Salt Lake Valley act as a funnel, forcing air flowing south off the Great Salt Lake to move directly into the valley, giving a boost to more snowfall.
Since 1998, the Great Salt Lake has helped generate from three to 20 lake effect snowstorms each winter, most of them relatively small and affecting some areas but not others. The average is about a dozen lake effect storms each winter, Steenburgh said.
is a rich spectrum of lake effect snowstorms, Steenburgh says. cover a wide area with light snowfall. Some organize into more intense snow bands that produce heavier snow over a smaller area. Over the Great Salt Lake, 20 percent of our lake effect events are these narrow intense bands.
