Dr Patrick Squires (19141990)No. 296 March/April 1991
Dr Patrick Squires, one of the pioneering giants of cloud physics, passed away on 14 November 1990, at the age of 76.
Dr Squires was born in the Melbourne suburb of Carlton on 12 July 1914. He attended Assumption College at age 10 in the seventh grade, and completed the tenth grade at age 13, in preparation for a career as a priest. However, he spent his next two years independently studying science, and at the age of 16 entered the University of Melbourne. He received his Bachelor of Arts degree in Mathematics from that University in 1934.
He left the University during the Depression and worked initially in the actuarial department of an insurance company. In 1937 he joined the Bureau of Meteorology and trained as a meteorologist with John Lillywhite, Neil McRae and other Bureau identities of that era.
Following the war he joined the Radiophysics Division of the CSIRO. In 1946 and 1947 experiments by Schaefer and Langmuir generated virga by dropping dry ice into wintertime stratocumulus cloud decks. Kraus and Squires took advantage of the difference in seasons to seed summertime cumulus clouds in Australia. in early February 1947, a particularly favourable weather situation resulted in an experiment southwest of Sydney which suggested that cloud seeding can, on occasion, result in changes in local weather.
Dr Squires' Australian work with Stewart Turner on air parcel cooling due to mixing at cloud top, and the descending thermals which transported this drier mixed air deep into the cloud, was a pioneering effort in an era which is still a subject of vigorous investigation in cloud physics. Much of his work was conducted in collaboration with Jack Warner, Jim Telford and Sean Twomey.
In 1962 Dr Squires joined the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, as a program scientist, where he also served as an adjunct professor with the State University in Fort Collins, Colorado.
