Studies on Local Climatology (VII) Temperature Distribution and Surface Covers

抄録

Conditions of surface covers play an important role as a principal factor as well as topographical features on local climates. The author made two local climatological observations on temperature distribution at the places where local differences in surface covers are remarkable and they occupy only about several square kilometers respectively.<BR>Observations were done in the daytime of calm days in summer 1947 using several Assmann's psychrometers by means of mobile observations on foot. And we reduced each observed temperature at different time to an average condition during the observation period using a repeated observation method by the same author.<BR>The magnitudes of temperature differences by various surface covers were recongnized with statistical significances: it was warmer at cultivated fields, bare- and bush-lands and cooler in forests, grass- and marshy-lands. Mean differences in temperature between them were usually 0.6-1.0°C.
