Rainmaking

Among the best-known and most successful of His Majesty's water provision projects has been the Royal Rainmaking programme. After visiting the United States in 1962, he began to study how clouds might be seeded to produce rain. In 1969 he carried out preliminary tests at Khao Yai National Park using a Cessna 180 and dry ice. In August 1969, he moved to Hua Hin and used two aircraft in a variety of weather conditions to determine what worked best. Initially, he financed the research with his own funds but in 1970, he sought temporary funding for a "Rainmaking Project" from the government. With it, he established the Royal Rainmaking Research and Development Institute. Based on it, he has spent succeeding years refining his techniques to accord with varying cloud conditions and to suit differing climatological and geographic areas, enjoying considerable success throughout Thailand. He continues to investigate new techniques. In 1999, he devised what he called the "Super Sandwich". After agitating and fattening the clouds, two aircraft are sent aloft, one to seed dry ice in the warm sections of the cloud base, the other to seed the cooler cloud mass at 3,000 metres elevation. Rain invariably falls on the parched land.
 
 
 
 
The Royal Rainmaking Project was registered with the World Meteorological Organisation in 1982 and today shares research data with similar bodies around the world. In 1999, he created a pictorial "Royal Rainmaking Textbook" to guide others pursuing the technology. In 2001, he was awarded the Gold Medal with Mention at Brussels Eureka 2001 for this book and for the project itself. In August.2002, the Thai Cabinet designated 14 November of each year as "Father of Royal Rainmaking Day" to honour his work in the field.
