Abstract通过对2001年4月的一次中亚强沙尘暴过程的观测事实分析和数值模拟,结果表明,源自中亚的强沙尘暴扬起的粉尘,通过西风急流远程传输到韩国、日本、北太平洋、北美大陆.北太平洋地区的沙尘沉积通量空间分布将主要取决于3个方面:沙尘沉积通量随传输距离的增加呈指数衰减;传输路径上粉尘有较高的沉降通量;沙尘过境时的降水空间格局将在很大程度上决定粉尘的沉降空间格局.
Other AbstractThrough the observation actual analysis and the numerical simulation of a strong dust storm event from mid-Asia at April 2001, the results showed that the dust from this storm was transported far to Korea, Japan, the Northern Pacific Ocean and Northern American continent through westerly jet flow. In Northern Pacific region the dust deposition depended mainly on three aspects: the exponential attenuation of dust deposition fluxes with increase of transport distance, the higher dust subsidence fluxes on the transport way, and the decision of dust subsidence spatial pattern by the raining spatial pattern at very great degree when the dust passed through the territory.
