Abstract
This study approaches are to obtain regional snow information relathionship between chemical composition and short period snow fall event for future environmental problem(climate change, environmental load and so on). We set temperate zone heavy snow area(Fukushima prefecture) as study area. This study results((1)-(3)) is as fellow. (1) An ion and an element are high contain rate of non sea salt concentration in amphitheater and urban area as first snow period. (2) In case of low total ion concentration, non sea salt concentration is high depend on regional condition. (3) Snow fall ions make a transformation regional geographical condition(water area, amphitheater, obstructed geographical condition area.).
