Abstract
In case there is a need to run the multi-year urban scale air qulaity model, it is a difficult taskdue to the computational demand, requiring the statistical approach for the long timeatmospheric environmental assessment. In an effort to approach toward long term urbanassessment, the sixteen synoptic meteorological conditions are statistically classified from theestimated geostrophic wind speeds and directions of 850 hPa geopotential height field during2000 ~ 2005. The geostrophic wind directions are subdivided into four even intervals (north,east, south, and west), geostrophic wind speeds into two classes(≤5m/s and >5m/s), and dailymean cloud amount into 2 classes(≤5/10 and >5/10), which result into sixteen classes of thesynoptic meteorological cases for each season. The frequency distributions for each 16 synopticmeteorological case are examined and some discussions on how these synoptic classificationscan be used in the environmental assessment are presented.
