Provided are a method and system of verifying an increase in precipitation. The precipitation increase verification method includes: obtaining a first piece of observation information from an upwind area after a seeding experiment; obtaining a second piece of observation information from a downwind area; comparing the first piece of observation information with the second piece of observation information, and thus determining whether or not the first piece of observation information and the second piece of observation information fall within a linear scope; and determining that an effect resulting from the seeding experiment can be proved when the first piece of observation information and the second piece of observation information fall within the linear scope.

Method and system of verifying increase in precipitation

The present invention relates to a method for determining a seeding effect area and a non-seeding effect area in accordance with a wind system according to the present invention can use numerical simulation data, radar precipitation data, and ground precipitation data to systematically specify the steps of determining the seeding effect area and the non-seeding effect area in accordance with the wind system. Moreover, the method according to the present invention can easily divide the seeding effect area and the non-seeding effect area according to the physical properties of clouds and quantitatively verify the effectiveness of artificial precipitation experiments conducted by purpose in the future.

Method for deciding seeding effect area and non-seeding effect area in accordance with wind system

A method is provided of calculating the total amount of artificial precipitation in a seeded area compared to a non-seeded area, which is capable of increasing the reliability of quantitative determination of seeding effect, observation data, and numerical model prediction data obtained from artificial precipitation experiments, of increasing the amount of water resources through weather modification experiments, of accomplishing various effects (drought reduction, forest fire prevention, fine dust reduction, fog reduction, hail suppression, etc.) and other related applications through artificial rainfall experiments, of improving the accuracy of correction and prediction of a numerical model obtained through weather modification experiments based on observation data, of establishing experimental and observation strategies for improving seeding efficiency in weather modification experiments, of developing the field of study on cloud development and fine physical changes in the cloud after seeding, and of improving the economic feasibility of artificial rainfall experiments.
