对札幌市1995~2002年8年间空气中花粉的产状进行了研究。对雪松、桦树、草和艾草的花粉季节进行了观察。桦树花粉的数量每年都有很大的变化。用最小二乘法进行一元线性回归，研究了白桦花粉年数量与气象因子的相关性。前一年2月降水量与年白桦花粉浓度呈极显著正相关(P=0.00004)，相关系数R2=0.950。这些结果表明，大气中的桦树花粉数可以根据前一年的气象因子进行预测。
Occurrence of airborne pollen in Sapporo was studied for the 8 years between 1995 and 2002. Observations on pollen seasons of cedar, birch, grass, and mugwort are presented. There are wide year-to-year variations in quantities of birch pollens. Simple linear regression by the least squares method was used for studying correlations between annual quantities of birch pollen and the meteorological factors. A highly significant (P = 0.00004) positive correlation was found between precipitation in February of the preceding year and annual birch pollen concentrations with the coefficient of determination, R2 = 0.950. These results suggest that atmospheric birch pollen counts can be predicted from the meteorological factor in the preceding year.
