Veteran Polish weather expert joins staff of Smithsonian Institution. Washington, D.C. March 14. With home, laboratory, and invaluable records of years presumably lost in the recent Polish War, Dr. Henryk Arctowski, of the University of Lvov, one of Poland's foremost scientists and former Antarctic explorer, has started at the Smithsonian Institution the monumental job of determining direct effects of changes in the Sun's radiation on weather conditions on Earth. Recognized in all countries as one of the greatest living authorities on world weather, Dr. Arctowski is continuing his studies in efforts to find relationships between solar conditions and rainfall, barometric pressure, etc., at various places on Earth. His earliest meteorlogical observation began as a young geologist on the Antarctic exploring ship Belgica in 1897-99. For release morning papers of March 18 - 40
