5203 |a"In this study, Brunt's equation for predicting the decrease in temperature with time after sunset is applied to the short-range prediction of minimum temperatures at five locations in Western Canada. These locations are Edmonton, Calgary, Saskatoon, Regina and Winnipeg. In order to apply Brunt's method, it was initially necessary to evaluate the product of the soil denisity, specific heat and the square root of the coefficient of termal conductivity. This was done empirically. Minimum temperature predictions were then made using data for a two month period at each of the five locations. In performing these predictions, nights during which temperature advection occurred were excluded from the test. However, cloud cover was taken into account using a scheme suggested by Reuter. Mean absolute errors between predicted and observed minimum temperatures varied from 2.3 degrees at Edmonton and Regina to 3.0 degrees at Calgary and the R.M.S. deviations ranged from 2.9 degrees at Regina to 4.0 degrees at Calgary"--Abstract.
