Use of models in weather modification - solutions or confusion?
Keywords:Weather Modification Research
One measure of our understanding of natural and artificially modified cloud and precipitation processes is our ability to simulate the essential features of their evolution through the use of numerical cloud models. I emphasize in this statement that modelers attempt to simulate only the essential features of clouds, the characteristic sequence of events manifested by these processes. It should be recognized that even if precise initial conditions were known, the physical assumptions and numerical techniques required to make models computationally tractable would make the exact simulation of a particular cloud unlikely. However, a model can provide insight into the characteristic behavior of clouds that develop in the air mass represented by a given sounding. By making several runs with reasonable variations in initial conditions that are deduced from observations, it should be possible to describe the range of cloud types that could be expected........
