Abstract:

A recent literature search found no formal definition of cold-wet climatic conditions, but rather attempts to explain why cold-wet conditions make one feel so cold. None of these were entirely satisfactory or proven experimentally. Further, no standard definition of cold-wet or cold-damp was found. An ABCA standardization agreement describes the principle climatic environments in the world. The one closest to cold-wet is CO - mild which represents Western European weather conditions. The temperature range is from - 6C for a daytime high to -19C for a nighttime low. The humidity is at saturation and there is no solar radiation. This is considered to be somewhat cold in Canada and any precipitation would be frozen, and not wet. In order to determine whether or not cold-wet can be characterized, weather data for 12 Canadian centres as well as for Baden-Soellingen, West Germany were analysed. It was hypothesized that at about 0C, it will be cloudier and foggier, there wil be more precipitation, the humidity will be higher, it will be windier and the barometric pressure will be lower. This paper gives the results of this study.
