In 1969, after a long continuous study for 14 years, the project of artificial rainmaking has proved successfully, Dr. Sawaeng Kulthongkhum, the Permanent Secretary of the Ministry of Agriculture and Cooperatives (MOAC), learnt that the Ministry had some small aircrafts under the responsibility of the Agricultural Aviation Unit which were being used for insecticide spraying. In response to His Majesty’s idea, he revived His Majesty’s initiative on rainmaking and put it into a real test. He assigned M.R. Debbrihi Devakul to prepare a rainmaking experiment project proposal. Subsequently, M.R. Debbrihi Devakul drafted a research and development project on rainmaking by means of cloud manipulation and submitted it to the Permanent Secretary, requesting permission to establish a Royal Rainmaking Operations Unit consisting of officers from various agencies under the MOAC, headed by himself, and supervised by the Permanent Secretary. M.R. Debbrihi’s scheme was approved and the implementation started in June 1969.
The Theoretical Background
The first principle was to use an aircraft to seed substance (sea salt) into the atmosphere to absorb moisture, then to use cold formula substance (dry ice) to make moisture condense and coalesce (the initiative in weather modification for making rain).
