Atmospheric pollen grains of Cryptomeria Japonica in Sendai City were collected by Durham's pollen trap and Burkard's one from 1983 to 1987. Analyzing the relationship between pollen count data and meteorological data in detail, we could obtain the following results. The total count of Cryptomeria Japonica pollen of the following season is closely dependent upon the mean humidity, temperature and sunshine duration in August using double regression analysis. It is possible to predict the total pollen count in the following pollen-season utilizing these data in August obtained from the Japan Weather Association. Furthermore both data atmospheric pollen collected by Burkard's trap and an hourly data of weather obtained from the Japan Weather Association made our understandings on various meteorological conditions of pollen dispersion clearer. Pollen count forecasts on Cryptomeria Japonica will be started in Sendai soon.
