A semi-empirical determination of the shape of cloud and rain drops / by 260440 Pruppacher, H. R., Pitter, R. L.

“…The results of our investigation show that the drop shapes predicted by the model agree well with those experimentally observed in our wind tunnel. Both theory and experiment demonstrate that: 1) drops with radii <170 u are very slightly deformed and can be considered spherical, 2) the shape of drops between about 170 and 500 u can be closely approximated by an oblate spheroid, 3) drops between about 500 and 2000 u are deformed into an asymmetric oblate spheroid with an increasinglypronounced flat base, and 4) drops >2000 u develop a concave depression in the base which is more pronounced for larger drop sizes. …”
