| Abstract | ||
| Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds. Cloud seeding is actually a very complex process. In the simplest terms, it introduces other particles into a cloud to serve as cloud condensation nuclei and aid in the formation of precipitation. The aim of this research is to simulate warm cloud seeding by liquid solution drops. A numerical model of warm cloud was developed and implemented by Fortran programming language. Numerical simulation of warm cloud seeding by slat solution showed that growth of most drops depends on seeding density value, the rate of growth of the cloud drop increase with increasing seeding density in a non linear way. The results illustrated that the radius of the large drop plays an important role in growth process while very small radius of small droplets has almost negligible effects on the growth process. It was found that rainfall is increased when seeding density is increased from 0 (the case of no seeding). The results also showed there is an optimum value for seeding density that gives the relatively largest amount of rainfall. Beside seeding density, the updraft radius of the cloud plays an important role in the formation of rain. Therefore the proper seeding density to be used depends on the updraft radius of the cloud. | ||
