关于我国和东亚酸性物质的输送研究──I.三维欧拉污染物输送实用模式

Studies on Transport of Acid Substance in China and East Asia Part I: 3-D Eulerian ransport Model for Pollutants

本文发展了一种三维欧拉型污染物长距离输送实用模式，比较详细地考虑了源、输送、干、湿沉降、气、液相化学过程。用分裂解法对气相化学过程进行查表式处理，颇具特色，使用实测气象输入场，节约了大量的计算机资源。通过模式的灵敏度试验，模式具有较高的分辨率和灵敏度。根据与实测资料对比，模式有较好的可信度，能方便的计算长时间（月、季。

A practical 3-D Eulerian transport model for pollutants is developed. It considers in details the emission, transport, gas-phase and aqueous chemical process, dry deposition, rainout and washout processes. It deals with gas-phase chemical process with look-up table or splitting method. The model has good resolution and sensitivity by the study of response with parameters. Through the comparison with observations, it is reliable and able to calculate conveniently the deposition and long range transport of contaminant for long time (e.g., for month, season and year).
