HYSPLIT（HYbrid Single-Particle Lagrangian Integrated Trajectory）模型是一个完整的系统，用于计算简单的轨迹，以使用喷烟或粒子方法进行复杂的弥散和沉积模拟。该模型使用以前网格化的气象数据的三个共形地图投影（极地，兰伯特，墨卡托）之一。空气浓度计算将污染物种类的质量与喷流、颗粒或两者的组合的释放相关联。根据垂直扩散率廓线、风切变和风场的水平形变计算扩散率。空气浓度是在特定的网格点上计算的，对于泡芙和颗粒物，空气浓度是计算的。
The HYSPLIT (HYbrid Single-Particle Lagrangian Integrated Trajectory) model is a complete system for computing simple trajectories to complex dispersion and deposition simulations using either puff or particle approaches. The model uses previously gridded meteorological data on one of three conformal map projections (Polar, Lambert, Mercator). Air concentration calculations associate the mass of the pollutant species with the release of either puffs, particles, or a combination of both. The dispersion rate is calculated from the vertical diffusivity profile, wind shear, and horizontal deformation of the wind field. Air concentrations are calculated at a specific grid point for puffs and as cellaverage concentrations for particles.
