城市空气污染预报方法简述

摘要

概括论述了城市空气污染预报的基本方法(潜势预报、统计预报和数值预报)、数值预报的主要特征(空间尺度与预报时效、高分辨率、多化学物质、理化生过程耦合、污染气象与污染物排放特征)及其用于天津和沈阳等城市的空气污染数值预报模式系统(σ中尺度和β中尺度气象预报模式与城市空气污染预报模式)。%Principal methods of urban air pollution forecast(potential, statistical and numerical method),main characters of numerical method (space dimension and computation efficiency, high resolution, multiple chemical species, coupling of physical, chemical and biological processes, features of pollution meteorology and pollutant emission) and model system applied in cities of Tianjin and Shenyang of air pollution forecast numerically (meteorological models of meso-αand meso-β, urban air pollution forecasting model) are discussed generally.
