The simultaneous and continuous recording of two meteorological parameters, atmospheric pressure in a meso-scale network of microbarographs and precipitation by a 3-cm radar, permitted the study of two pressure phenomena (jump line and pressure dome) in relation to precipitation. The jumps were found to be of two basic types, one followed by a pressure dome and associated with severe weather, and the other showing as a step on the barograph traces and not associated with weather. The pressure domes were found to be closely associated with precipitation, some starting with, some developing towards and others intensifying with the radar echoes. In a preliminary study, it was shown how valuable information about pressure phenomena can be obtained from data (wind, pressure, precipitation) collected at one single station, rather than throughout a network.
