Drought condition had frequently occurred in Thailand. El Nino phenomenon was the essential cause of this severe drought during 1999-2000. Thailand had faced a severe crisis, such as, the critical water levels at dams, crop loses, forest fire, rising sea level in Chao Phraya River due to the lower level of water in the river. The government announced measure to save water and reduce cultivated area during that period. People were suffered from the lack of water consumption. Furthermore, the government warned farmers of restricting cultivated area for dry season rice. Thai farmers became concerned and panic.
According to His Majesty King Bhumibol Adulyadej’s concern over the poverty of his people, he closely followed drought situation and extreme weather conditions in 1999. Since the end of January 1999, he suggested to set up a special rainmaking operation team in order to operate at Nakhon Sawan and Phitsanulok to solve the drought problem in upper central river basin, Chao Phraya river basin and lower northern river basin.
His Majesty King Bhumibol Adulyadej also improved the Royal rainmaking method to be a higher level by developing weather modification called ‘Super Sandwich Technique’ which involves warm and cold cloud attacking techniques at the same time. Furthermore, the Royal rainmaking process was concluded in a Royal rainmaking technology which is a computer-drawing in a form of cartoon by His Majesty King Bhumibol Adulyadej to describe the process and weather modification method. Straightforwardly, this process was briefed completely in one page and was given to the Royal rainmaking academicians as a guideline. This computer-drawing named ‘the Royal rainmaking technology’ was applied in helping the unfortunate people to alleviate drought. The intelligence and generosity gained respect and admiration from his subjects toward our King.
The successful Royal rainmaking operation in resolving drought of two operation teams in 2000 and the monitoring of Royal rainmaking technology team had confirmed the success in preventing and copping with drought. Subsequently, Bureau of the Royal Rainmaking and Agricultural Aviation was granted to use and publicize Royal rainmaking technology in helping people afterward.
