Rain or snow? Humidity, location can make all the difference

March 23, 2018

By Trent Knoss , CU Boulder Today . CU Boulder researchers have created a map of the Northern Hemisphere showing how location and humidity can affect precipitation, illustrating wide variability in how and why different areas receive snow or rain. 32 degrees Fahrenheit is commonly considered to be the air...

GEOG 4321 Snow Hydrology

Are you interested in the various processes related to snow in mid-latitude and polar areas? You will learn the physics and chemistry that underlie processes such as snow metamorphism, and apply this knowledge to real situations, including calculation of basin storage of water, runoff rates, acid snow, and avalanche dynamics...

Earlier snowmelt carries drastic consequences for forests

Aug. 3, 2016

Earlier snowmelt periods associated with a warming climate may hinder subalpine forest regulation of atmospheric carbon dioxide (CO2), according to the results of a new University of Colorado Boulder study. The findings, which were recently published in the journal Geophysical Research Letters , predict that this shift in the timing...

CU-led mountain forest study shows vulnerability to climate change

Sept. 10, 2012

A new University of Colorado Boulder-led study that ties forest "greenness" in the western United States to fluctuating year-to-year snowpack indicates mid-elevation mountain ecosystems are most sensitive to rising temperatures and changes in precipitation and snowmelt. Led by CU-Boulder researcher Ernesto Trujillo and Assistant Professor Noah Molotch, the study team...
