Publisher's Synopsis
Excerpt from Temperature Inversions in Relation to Frosts
We see then that there are various con?icting processes; for there is gain and loss of heat by radiation (the upper s10pes losing heat by radiation and the lower air masses gaining heat); retardation or acceleration of rate of temperature change by the change in state of the water vapor; direct gain or loss of heat by convection or the actual translation of cold and warm air masses; and finally some slight gain or loss by conductivity.
Unfortunately the term frost has been used as synonymous with lowest temperature, whereas it more properly is simply an indication of the exist ence of sufficient water vapor changed into ice in the form of spicular crystals. Such deposit does not necessarily indicate the place of lowest temperature, for with other than saturation conditions, lower temperatures may prevail without the crystals forming.
