摘要
对1981-2010年30年深圳日雨量及降水频次的周末效应特征进行了检验,结果表明,30年降水频次、平均日雨量均存在周末效应,周六降水频次、平均日雨量均高于周一;各年代降水频次周末效应随着时间的推进而逐渐减弱,而平均日雨量周末效应却随着时间的推进在缓慢增强;四季中,降水频次均存在明显的周末效应,平均日雨量只在春、夏季存在周末效应;30年平均相对湿度和各年代平均相对湿度均与平均日雨量有较好的对应关系;近几年资料分析表明,平均日雨量与可吸入颗粒物浓度具有反相关系。
The weekend effects of the daily rainfall and rain frequency during the years of 1981-2010 are analyzed.The results show that the weekend effects of the 30-year rain frequency and the average daily rainfall have been confirmed.The rain frequency and the average daily rainfall on Saturday were larger than those on Monday.The weekend effect of the rain frequency on each time weakened with time,while the weekend effect of the average daily rainfall increases with time.In four seasons of the year,the weekend effects of the rain frequency are all confirmed.Only in the spring and the summer,the weekend effects of the average daily rainfall are confirmed.The weekend effect of average relative humidity in 30-year and each time have a good correlation with the average daily rainfall.In recent years,data analysis showed that the average daily rainfall and the inhale-particles(PM10) index has the inverse correlation? on weekend effect.
