SOME OBSERVATIONS OF NIGHT MINIMUM ROAD TEMPERATURES

AIR AND ROAD SURFACE TEMPERATURES WERE MEASURED DURING TWO SUCCESSIVE WINTERS AT EACH OF TWO SITES. DIFFERENCES IN THE NIGHT-MINIMUM VALUES OF THESE TEMPERATURES WERE GENERALLY SMALL AND NO SYSTEMATIC VARIATION WITH A NUMBER OF METEOROLOGICAL AND OTHER PARAMETERS WAS EVIDENT. TWO TYPES OF SITUATIONS WERE RECONIZABLE HOWEVER, IN ONE OF WHICH THE MINIMUM AIR TEMPERATURE WAS CONSISTENLY HIGHER THAN THE MINIMUM ROAD TEMPERATURE AND IN THE OTHER, CONSISTENTLY LESS, THE DIFFERENCE BEING UP TO 3 DEG.C OR SO AT TIMES. /A/RRL/
