Thermal Patterns in the Snow: Icicles as Indicators of Heat Loss
Bartlett, Albert A.
Physics Teacher, v46 n3 p172-177 Mar 2008
On Dec. 27, 2006, we drove with our children and their families to a cabin we rented on the grounds of the "YMCA of the Rockies" in Estes Park, CO, for a few days of winter relaxation and recreation. On the night of the 27th a snowstorm dropped over half a meter of new snow, creating a beautiful winter wonderland. For the next couple of days the Sun shone brightly but the temperatures stayed well below freezing, so the combination of time and temperature cooperated to produce some spectacular thermal patterns in the snow on the roofs of the buildings. In the following days I walked a great deal, using my new digital camera to photograph these evolving thermal patterns, a subject that first fascinated me more than 30 years ago. This time the thermal patterns were dramatically complemented by the presence of icicles.
