Relationships between chemical compositions and meteorological conditions for fog and rain at Hachimantai range, and rain at Akita city in Japan.

Abstract

Acid fog and rain samples were collected at Mountain range of Hachimantai and at Akita City in Japan. Various ion concentration of these sample were analyzed using an ion chromatography and pH meter. The NO₃- concentration of rain at Akita increased gradually year to year. The fog water had a high concentration of various ions compared with the rain. The highest concentration was observed in the weather chart of high pressure on Japan Island. The fog water had a low concentration for various ions in autumn compared with those in spring, so that this result agreed with the fact that the autumn sky is clear and clear in Japan.
