MEAN ANNUAL MID-LATITUDE MOISTURE PROFILES TO 31 KM

Abstract

Average yearly vertical profiles up to 31 km for middle latitude, derived independently, for mixing ratio and moisture dewpoint-frostpoint, are presented. Since the relation between mixing ratio and frostpoint is non- linear, other moisture expressions were derive from each of the two basic profiles, using standard atmosphere conditions. Up to 7 km, the profiles were derived by an indirect approach; conventional radiosonde humidity measurements were utilized. Above that level the profiles are based upon selected experimental humidity ascents, subjectively selected and weighted. The mixing ratio profile decreases from 6150 parts per million (PPM) at the surface to 9 ppm at 16 km then increases slightly with height; the surface dewpoint is taken as 4 C, decreasing to -78 C at 18 km, then increasing to -71 C at 31 km.
