Pre-medical treatment before pollen dispersal is important for Gramineae pollinosis. To estimate the starting date of pollen dispersal, we investigated the relationship between grass-pollen dispersal and early spring meteorological data. For 22years, from 1984 to 2005, the quantities of dispersed pollen in Morioka City, were observed daily using a Durham Sampler. As an index, the earliest starting day for pollen dispersal (EDPD) was defined as the date when 0.3/cm^2/day was observed for two consecutive days. Meteorological data were collected from the database provided by the Morioka Local Meteorological Observatory. The correlations with the EDPD were calculated based on the accumulated daily mean-, maximum- and minimum-temperatures, accumulated sunshine duration, and accumulated amount of global solar radiation from April 1^<st> to 15^<th>. As a result, the highest correlation coefficient (r=-0.831, p<0.001) was obtained between the EDPD and the accumulated daily maximum temperature. The mean and range of the EDPD from 1984 to 2005 in Morioka City were April 30.3 and the period from April 15^<th> to May 16^<th>, respectively. Using a regression equation y=-0.2529x+168.53, where 'x' is the accumulated daily maximum temperature from April 1^<st> to 15^<th>, we could estimate the earliest starting day of pollen dispersal with an accuracy of ±4.1days.
