Rain Seminar

One of the most ambitious initiatives of the Dwyer years was the organisation of a rain seminar which, through the cooperation of Professor Harry Messel of the Physics Department of the University of Sydney, was held in his Department from 15 to 23 August 1960. Gerry O'Mahony had returned from the ANU and Allan Rainbird was about to be attached to SMHEA for twelve months so it was an ideal opportunity for Len Dwyer to stage the rain seminar and he took an intense personal interest, despite a busy program of national and international activity.

Fifty papers were presented by members of the Bureau, CSIRO, water authorities and universities. Participants numbered 55. Twelve were from the Bureau's Central Office, 15 from the Bureau's Divisional Offices and one from the Bureau's Mascot aerodrome office. Nine came from water authorities, seven from the CSIRO Division of Radiophysics and three from the Division of Meteorological Physics. Six came from universities and one each from a soil conservation authority and the Hunter Valley Research Foundation.

Three volumes containing synoptic case histories, tables of rainfall data and a precipitation notebook were distributed to participants prior to the seminar. Two more volumes published after the seminar provided the text of papers and a record of discussions. In all the five volumes contain over 1000 pages. The Bureau provided many man-hours in organising the seminar, producing the publication in addition to the time spent by those individuals who prepared papers.

The seminar had twelve sessions each focussing on special aspects of rainfall including cloud dynamics, formation of rain, condensation and freezing nuclei, rainfall statistics, artificial stimulation, instruments and observations, temporal and spatial distribution, the rain process, forecasting (including numerical and statistical methods), synoptic aspects and finally a panel discussion summarising the outcome of the seminar.
