The meteorological information for atmospheric environment's most basic information, contains the temperature, important items and so on, barometric pressure, wind direction, wind speed, stability, mix level altitude, the content is diverse, and the material quantity is huge. Because the meteorological condition to includes the nuclear radiation and the biochemistry pollution proliferation has the quite important influence, under the limited transmission space and the time condition, how to establish an optimization the meteorological information, take grasps the related meteorological essential factor as this research discussion key point. This research unifies the SCIPUFF nuclear pollution proliferation analogous system, the analysis different meteorological factor to of analogue result the pattern influence, grasps the meteorological essential factor. In the SCIPUFF nuclear pollution proliferation analogous system meteorology mold train application, compared to demonstrated analysis of by way of the meteorological factor to the result that the atmospheric environment meteorological factor besides the wind speed and the temperature, the atmospheric stability also for the essential factor which essential has, enables the pollution proliferation analogous system to have the best simulation effect. Simultaneously when has also confirmed the pollution proliferation, is by the low wind speed, the high stability atmospheric condition may create the best diffusion effect. In addition, the mix level altitude to pollutes the proliferation the influence function not, if the atmospheric stability is obvious, the primary cause is mixes the level altitude the performance also to conceal the atmospheric stability essential factor result.
