Abstract : Intensity contour data from several long storms containing widespread light rain or snow were added to the backlog of quantitative data on winter storms. In instrumentation work excellent progress had been made on devices for quantizing the output from the delay-line integrator and for displaying several intensity levels simultaneously. An F-M sweep integrator for use with short pulse on the AN/CPS-9 radar is also progressing well and should be in operation some time during the summer. In addition, an RHI for the SCR-615-B radar is under construction. Investigations of measurement of rainfall over an area are continuing. Excellent results are obtained at close ranges, but in certain types of storms at ranges beyond 40 miles, effects related to the filling of the beam and the height of the radar horizon above the ground become apparent. Computations concerning the dispersion of the radioactive cloud from a 10Kt detonation have been completed for a selected wind field, one in which the wind speeds involved are of average magnitude.
