Abstract : During the winter of 1964-1965, approximately one year before the major explosion at Medeo, which was 'designed to control some of the runoff problems originating in the 'seley' avalanche-floods,' a major micrometeorological field study was undertaken to investigate the day-time atmospheric circulation in the Malaya Atmatinka river valley. These data were supplemented by aerological observations made at the Alma-Ata Hydrometeorological Observatory (7 km below the mouth of the valley). The experimental data included 1119 pilot balloon and 1259 gradient observations (temperature and wind measurements) collected at three stations and radiosonde observations from Medeo itself. The investigation covers, in great detail, the frequency of occurrence of typical mountain-valley circulation (three observation stations distinguishing mountain winds, valley winds, calms, and weather conditions which hindered pilot balloon observations, such as precipitation, fog, low clouds etc.). The principal findings of the study of local circulation prevailing in the daylight hours of the winter season are summarized. (Author)
