Application of Numerical and Statistical Methods to Contingency System for Nuclear Power Plants in Guangdong
数值与统计方法在广东核事故应急系统中的应用

Based on three years' meteorological data obtained from the routinely meteorological stations in the studied area, some different weather types were measured off by meteorological factors, such as season, weather and hourly wind speed and direction. Its wind and temperature fields were simulated by mesocsale meteorological model in order that the simulated wind and temperature fields can render effects of thermal and dynamical inhomogeneity of underlying surface. With these fields, correlation of meteorological factors of concerned points with weather types could be built statistically, and relevant wind and temperature fields could be found by this correlation and used as forecasted ones to calculate concentration distributions of unclear pollutants when meteorological factors of concerned points were known.
