Weather modification by royal rainmaking technology

Abstract

Process of rainmaking and moving cloud using ‘Royal Rainmaking Technology’ is described for weather modification by means of chemical seeding comprises steps of “Triggering”, to activate cloud formation; “Fattening”, to promote cloud growth; “Moving”, to move cloud to a designated area, and “Attacking” to initiate rainfall from cloud. Attacking can be done by at least 3 different techniques; by ‘Sandwich Seeding Technique’ for ‘warm cloud’, by ‘Glaciogenic Seeding Technique’ for ‘cool cloud’, or by ‘Super Sandwich Seeding Technique’ for mixed phase cloud. ‘Enhancing’ is for enhancing amount of rainfall and prolonging raining duration including increasing area coverage. Weather modification extends to dispersion of cloud into clear flight path, prevention of hail formation, and inducing rainfall from stratiform clouds onto a valley or any catchment areas. Seeding may be performed inside or outside a cloud or to the top or underneath any isolated cloud or cloud band.

Description

FIELD OF THE INVENTION [0001] This technology of rainmaking involves the knowledge of meteorology, climatology, cloud formation, cloud evolution, rain formation and cloud dispersion of various aspects. BACKGROUND OF THE INVENTION [0002] This technology is termed the ‘Royal Rainmaking Technology’ as it is a unique technology invented by HIS MAJESTY KING BHUMIBOL ADULYADEJ OF THAILAND. The technology is developed to help people in Thailand and particularly those farmers who repeatedly face drought disasters due to variation and deviation of the seasons, and in addition as an attempt to solve a seemingly insoluble and paradoxical problem of water management in the North-East region of Thailand, i.e., when there is rain, the water is too much that it floods down the hills because there are not many trees to stop it and thus floods the area, but when water recedes it turns to drought. The solution to this problem is to build many small check dams along the creeks on the hills to regulate...

Benefits of technology

[0016] The present invention relates to technology for weather modification for rain making and moving water in form of cloud from an area to fall as rain onto a designated target area far away. The process comprises steps of ‘Triggering’ which is a technique to activate cloud formation using fine powder of hygroscopic materials such as sodium chloride; ‘Fattening’ which is a technique to encourage or promote cloud growth by dispersing giant nuclei of exothermic-hygroscopic materials such as calcium chloride to cause updraft by exothermic reaction and thereby activate collision and coalescence of the cloud droplets; ‘Moving’ which is a technique to move cloud mass to a designated target area; and ‘Attacking’ which is a technique to initiate rainfall from the cloud. Step of attacking can be done by at least 3 different techniques. Firstly, by ‘Sandwich Seeding Technique’ for ‘warm cloud’ whose cloud top does not grow beyond the freezing level, giant endothermic-hygroscopic nuclei such as sodium chloride are dispersed into the cloud top and urea at the cloud base simultaneously to increase number of big raindrops and decrease the in-cloud temperature due to endothermic reaction which further increase downdraft within the cloud mass and big raindrops thus start to fall from the cloud base. Secondly, by ‘Glaciogenic Seeding Technique’ for ‘cool cloud’ whose cloud top grows well beyond the freezing level where super-cool droplets and ice crystals appear in the cloud top portion, silver iodide flares are burnt into the cloud top to produce rapid glaciation of the super-cool cloud liquid water content in the updraft that the rest of the cloud water can be rimed into graupels which grow much faster than raindrops of the same mass and thus converted into ice precipitation falling through the freezing level and finally melt into raindrops. Thirdly, by ‘Super Sandwich Seeding Technique’ for mixed warm and cool cloud (mixed phase cloud), where the ‘Sandwich Seeding’ and ‘Glaciogenic Seeding’ techniques are combined to provide higher efficiency for process of rain enhancement. Dropping flakes of dry ice at about 1,000 feet below the cloud base results in increase in relative humidity of the air mass underneath the cloud base. The rainfall rate increases gradually and big raindrops can reach the ground. Strong downdraft increases feed back of moist air into the treated and the neighboring cloud bases to cause continuation of rainfall, resulting in much more rainfall in terms of amount and area coverage as well as raining duration, thus called ‘Enhancing’. Weather modification further extends to dispersion of heavy cloud into clear flight path, prevention of hail formation, and inducing of rainfall onto a valley or onto any catchment area of the water reservoirs in various circumstances. Seeding may be performed inside or outside a cloud or to the top or underneath any isolated cloud or cloud band.

Problems solved by technology
