Record #112836:

The role of thermal convection in heat and mass transport in the subarctic snow cover / Matthew Sturm.

Title: The role of thermal convection in heat and mass transport in the subarctic snow cover / Matthew Sturm.
Author(s): Sturm, Matthew.
Date: 1991.
In: CRREL Report. (1991.), Vol. 91-19 (1991)
Abstract: Investigates role of air convection in moving heat and water vapour in snow. To detect convection, three-dimensional temperature field in snow cover at Fairbanks, AK, was measured hourly during three winters (1984-87). Measurements of snow density, compaction, and grain size were made monthly to determine water vapour flux and textural changes. Fairbanks snow was found to metamorphosize progressively until, by end of winter, it consists of depth hoar in sequence of five layers. Convection occurred sporadically in winter 1984-85 and continuously in 1985-86 and 1986-87.
