AbstractPermanent rainstorm records were produced by photographing radar type-A displays in conjuntion with the recording of meteorological data. The analysis has been proved that the rate of fall in rainstorms can be measured by radar with reasonable accuracy. Simultaneous quantitative measurements at three and ten centimeters agree with both theory and previous experimental results showing that radar echoes are dependant on drop size distribution, and are proportional to the sum of the sixth power of the drop diameters contained in a unit volume. Quantitative measurements have given an absolute comparison of X-band and S-band performance and have illustrated the limitations of X-band as a useful frequency in meteorological work. The data may be applied to any radar to estimate the detection ranges of typical targets in rainstorms.
