Abstract : Results are given of research conducted in three major areas: (1) the temperature and wind structure of cold fronts. (2) determination of the eddy heat coefficient under fair-weather conditions, and (3) the determination of the eddy heat coefficient in frontal zones. The investigations were based upon data collected on the 1420-ft. KRLD-WFAA transmitter tower at Cedar Hill, Texas. This volume pertains only to the first area. This section deals specifically with the structure of cold fronts. By making suitable assumptions it was possible to determine the motion of the air relative to the thermal fields of the fronts. The results indicated considerable cross-isentropic motion. In turn, these results implied, as extreme possibilities, that either the temperature structure of the fronts was undergoing radical change as a result of the particles following an adiabatic process or, the temperature structure was conservative and the particles were undergoing nonadiabatic processes.
