Abstract

Examination of National Hail Research Experiment (NHRE) mesoscale data taken on 31 July 1976 revealed significant fluctuations with time in the temperature, dewpoint temperature and wind speed. These variations displayed characteristics typical of summertime frontal passages. However, GOES-1 imagery revealed meso-β (weather systems having wavelengths of 20–200 km) scale features that were likely responsible for the observed phenomena. It is shown that geosynchronous satellite data can be of significant value in the analysis and interpretation of mesonetwork data.
