"An overlay to be applied to the Canadian Tephigram (Form 63-2394) for the prediction of maximum temperature is described in this paper. In order to apply the overlay, the amount of energy which is available for raising the temperature of air in the lower layers of the atmosphere must be known. A procedure for computing this energy which accounts for the depletion of solar radiation by reflection, absorption and terrestrial radiation is described. This method of maximum temperature prediction was evaluated using six months (May - October, 1967) of data for Edmonton, Alberta. When cases of temperature advection were excluded so that the temperature change was a result of solar insolation alone, it was found that useful predictions were possible. An error analysis made of 93 cases when advection was absent gave a mean absolute error of 2.68 degrees F and a RMS error of 3.45 degrees F between predicted and observed values of maximum temperature"--Abstract.
