It is the capital of the processes of rain induced water from the sky, which require air cargo rate was packed but more chemicals in the sky based on the moisture content of the clouds and the wind direction, the nature of the Assembly. Important factors causing the rain is cold and humid heat, there are clashes with kaenklan performance in appropriate quantities, that is, when a mass of air humidity at surface ground temperature of the air to air mass will lower till the height where level one. Lower temperature is enough to make steam in the air mass movement occurred until the saturated condensing of steam on kaenklan until becoming rain to fall. Therefore, these chemicals, it contains a formula to stimulate heat. Mechanisms of circulation of the atmosphere cold formula Used to stimulate the integration mechanism of the aerosol clouds, rain and grain is grown up the formula that is used as a moisture absorbent cores. To stimulate the mechanism system of condensing, higher efficiency. There are steps, as follows:Step one: vandalism Vandalism is a step to start the formation of natural clouds vertically. The execution capital of rain in this step aims to use chemicals to stimulate. The air mass is floating up to the induction process to produce water vapour or moisture into the system, causing clouds and periods that will be executed at this stage should not exceed 10.00 a.m. each day by using chemicals that can absorb water vapour from the air mass. Despite low relative humidity percentage to boost regulation of the process of condensing water vapor in the air mass. Wind North of the target area. When the clouds began to occur with the formation and growth of vertically using the chemicals, reactions, heat; But there is a circle, or in a row next to the South wind is a short distance into clouds to induce joint axis group operating in the area for use as a hub to create rain clouds in the next step. The second step: raising, fat. Raising a fat cloud of step is the formation of growth, which is a very important phase in implementing the capital because of the rain to add energy to the floating clouds, the heart of the issue. By using technology and experience, or the arts to make rain coupled together to decide what type of chemicals the capital of rain but at the place of the group, and the rate of cloud are appropriate because of the need to balance the emerging cloud aerosol processes with floating clouds, otherwise will cause clouds and disperse. Step three: attack. The attack is believed to be the last step of the operating methods of rain clouds and rain clouds or by the capital group has density enough to fall as rain. Within the group there will be a large cloud of water thousands of pills. If an airplane flying into the rain clouds are groups of tablets water Koh as wings and front cover of the plane which will be executed in order to reduce violence in the floating clouds, or make a floating life expired. For action at this stage to consider the aim of FON which are 2 issues is to increase the quantity of rain and caused an explosion of fall rain. With the importance and the quantity of operating capital to help more rain had significant. Therefore, to help dry the bulk so that multiple tasks execute executable capital rain helped farmers to a wider and more productive. The Government has enacted decree established the operating Office of capital defense. In the Office of the Permanent Secretary, Ministry of agriculture and cooperatives; When September 21 2518 (1975) as authority to accommodate the rain initiative project the next time the capital improvements and operating highways, raining development until today.
