Abstract

We collected rime samples on Mt. Zao (near the summit of Mt. Jizo) in two winter seasons (2002-2003 and 2003-2004) and major ionic components and sulfur isotope ratio of sulfate were measured. As a result, almost all the rime samples were obtained under the strong winter climate conditions associated with the flow of the northwestern monsoon from the Asian continent to Mt. Zao. The ∂34S values of non-sea salt sulfate in the rime samples ranged from 4 to 8 ‰ , and almost all the sulfur that originated naturally were transported from the sea. It appears that the formation of sulfur in rime is a result of the mixing of two components (sea water and anthropogenic sulfur). The results obtained indicate the strong possibility of long-range transport from the Asian continent to Mt. Zao through the lower troposphere.
