What Denver’s exceptionally dry fall means for the future of snow – Denver, Colorado

Denver, Colorado 2021-11-25 06:00:29 –

Think Denver Record-breaking dryness and snowless autumn, It’s hard to wonder how these anomalies will affect you in the long run. Is this weather a bigger signal of what’s to come?

I spoke with Noah Morocci, an associate professor and fellow at the Boulder Arctic Alpine Institute, University of Colorado. He analyzed the differences between observable climate change and periodic changes in mountain weather, and how the two phenomena interact.

One of the most important differences to note is that the weather and climate are not the same. Although weather can be volatile, unpredictable and short-term, the effects of climate change can be observed through broader, longer-term effects on weather trends.

Moroch explained that this year’s dryness is still within the normal range of year-to-year fluctuations, but the heat that exacerbates its harmful effects may be the result of climate change.

“There is a side [this year] It may represent the future, “Moroch said. “We expect that many of the early winter and autumn storms in the front range will occur as rainfall, not as snow.”

And unfortunately, climate change is only part of it. The problem of trapping the heat of the city.

The Denver Metro Area also asked what this dry spell was doing in the Rocky Mountains, as most of the drinking water comes from mountain snow.

According to Moroch, meteorological stations at altitudes of about 11,000 feet show about 80% of normal snow cover. However, when it goes down to 8,000 feet, or at least “relatively low,” snow cover drops to about 50% of the average.

“The amount of water normally stored in snow during this time is not very high anyway,” Moroch said. “But it’s not a good situation to start the season below average.”

Unseasonally warm temperatures and reduced snow cover at low altitudes are also Not so expensive ski resort troubles like Steamboat Springs. The heat leads to slow openings and thin snowfall, where snow cannot be blown.

But in addition to interfering with the early ski season, this dry spell has other, even more serious consequences. Specifically: Fire.As Kluger Rockfire demonstrated last week, Colorado is still in the wildfire season.

“These are the kind of concerns we usually have in more traditional fire seasons, such as late summer,” Moroch said. “Still, I’m here almost in December.”

We asked Moroch how much we should all be surprised about the water supply.

“We probably don’t have to worry yet, but there are some grounds to make up for snowfall,” Moroch said. “And I’m pretty uncertain if I can do that.”
