摘要
通过分析天津市1999-2005年的逐日花粉量与气象要素之间的关系,研究了相关气象要素对花粉浓度的影响。结果表明:气象条件不同,每年花粉浓度高峰期出现的时间以及花粉浓度存在很大差异,而且不同气象要素对花粉的影响程度明显不同。同时分析了不同降水、风力、云量条件下花粉量变化的百分比。根据此研究结果订正逐日花粉浓度预报方程,该方程的预报准确率较以前提高了9.5%。
The relationship of daily pollen concentration with meteorological elements from 1999 to 2005 in Tianjin was analyzed to determine the influence of meteorological elements on variations of pollen concentration.The results suggested there were large differences in both the emergence time of the highest pollen concentration and the pollen concentration in every year under different meteorological conditions.Different meteorological elements had significantly different effect on pollen concentration.The percentages of pollen concentration increase or decrease under different precipitation,wind speed and cloud amount were also analyzed.Based on the results in the present study,the prediction equation of daily pollen concentration was revised,and the forecast accuracy rate was increased by about 9.5%,compared with previous methods.
