Abstract: Many measurements of the snowfall rate R and the average mass per crystal m? have provided values of R/m?, the number of snow crystals reaching unit area of the surface per unit time. A typical number is 1 per cm.2 per ...

Abstract: According to Rayleigh scattering theory for small spheres, back scattering is proportional to |K2Z where K is the dielectric factor and Z is the sum of the sixth powers of the diameter D. For small non-spherical particles ...

Abstract: A transmissometer has been used to provide a continuous record with good time resolution of falling snow. The pulsed light, of wavelength 0.45?, traversed a path 71 m long about 20 m above ground level A total snow amount ...

Abstract: Precipitation particles which fall from a source aloft through a wind shear are sorted as to size, the largest particles reaching the ground closest to the generating source, the smaller particles further from it. If ...

Abstract: Average-size distributions for aggregate snowflakes are well represented above D = 1 mm by ND = Noe?AD where D is the diameter of the water drop to which the aggregate would melt. This is the same equation that Marshall ...

Abstract: The beam of a moderately sensitive 3-centimeter radar has been kept pointed to the zenith. Height/time records of snow echoes for seven winter weeks have been correlated with analyses of standard upper-air data. The major ...

Abstract: Vertical-section radar observations of precipitation in the winter of 1951?1952 have been related to upper-air data. On three of the 22 days, there was very little signal and practically no pattern observed. It is possible ...
