为了应用气象模式研究山地森林雾的发生、酸化和沉积，对气象模式WRF进行了修正，采用详细的多层大气-植被-土壤模型（SOLVEG），利用数值试验得到的雾沉积对植被的简单线性函数精确计算雾沉积。包括雾沉降在内的WRF改良版（fog-WRF）在日本六甲山的山林中进行了试验。fog-WRF对雾中液态水含量的预测明显优于原始WRF。它还成功地模拟了由于夏季森林内部雾沉积而导致的穿透观测，排除了森林边缘的影响。利用雾wrf计算得到的雾沉降与海拔高度之间的线性关系和给定海拔高度的穿透雨观测数据，可以粗略估计山地森林雾沉降的垂直分布。一个包含雾沉降的气象模型将有助于绘制山地云雾林的雾沉降图。
To apply a meteorological model to investigate fog occurrence, acidification and deposition in mountain forests, the meteorological model WRF was modified to calculate fog deposition accurately by the simple linear function of fog deposition onto vegetation derived from numerical experiments using the detailed multilayer atmosphere-vegetation-soil model (SOLVEG). The modified version of WRF that includes fog deposition (fog-WRF) was tested in a mountain forest on Mt. Rokko in Japan. fog-WRF provided a distinctly better prediction of liquid water content of fog (LWC) than the original version of WRF. It also successfully simulated throughfall observations due to fog deposition inside the forest during the summer season that excluded the effect of forest edges. Using the linear relationship between fog deposition and altitude given by the fog-WRF calculations and the data from throughfall observations at a given altitude, the vertical distribution of fog deposition can be roughly estimated in mountain forests. A meteorological model that includes fog deposition will be useful in mapping fog deposition in mountain cloud forests.
