Marshall and his doctoral student Walter Palmer later received recognition for their work on the drop size distribution in mid-latitude rain that led to the rain rate relation to radar reflectivity ( Z-R relation ).

The closer this number is to zero, the more uniform the spray will be ( i . e . tightest distribution, smallest variance from the maximum drop size, Dmax, to the minimum drop size, Dmin ).

To find a relationship between drop size and contact time for low Weber number impacts ( We \ rho R / \ tau ^ 2 ) and capillarity ( \ sigma / R ^ 2 ) can be used, as follows:

This method, also known as PDPA, is unique because the drop size and velocity information is in the phase angle between the detector signals and the signal frequency shift . Because this method is not sensitive to intensity, it is used in more dense sprays.

The terminal velocity depends on drop size, and as Horstmeyer explains here [ http : / / www . shorstmeyer . com / wxfaqs / float / dropdeform . html, the maximum drop size is 5 mm, as aerodynamic forces cause larger drops to break apart . talk ) 21 : 49, 24 December 2014 ( UTC)
