A global analysis of snow depth for numerical weather prediction

From: Journal of Applied Meteorology | Date: June 1, 1999| Author: | Copyright information

ABSTRACT

The operational analysis of snow depth at the Canadian Meteorological Centre is described. The analysis makes use of forecasts of precipitation and analyses of screen-level temperature to estimate snowfall and snowmelt for a global domain, and assumes persistence of the mass of the snowpack between melting and/or snowfall events. In addition, wherever snow depth observations are available, these are incorporated using the method of statistical interpolation, performed every 6 h on 1/3 deg grid. Correlations between two observations or between observations and grid points are taken ...
