采用积分式浑浊度仪于2012年1月在乌鲁木齐市中区和市北区对气溶胶的散射系数和吸收系数进行连续观测,分析了市中区与市北区气溶胶散射系数和吸收系数的变化特征,结合同期的相关气象资料对变化特征进行了讨论。结果表明,市中区和市北区气溶胶的散射系数、吸收系数具有相同的变化趋势。总体上呈“W”型;峰值分别出现在0:00和12:00前后,谷值则出现在5:00和17:00前后。散射系数远大于吸收系数,说明大气气溶胶的消光作用主要由散射作用完成。相对湿度与散射系数、吸收系数不具有显著相关性,而风速对散射系数、吸收系数影响较大,且对市北区的影响大于市中区。
採用積分式渾濁度儀于2012年1月在烏魯木齊市中區和市北區對氣溶膠的散射繫數和吸收繫數進行連續觀測,分析瞭市中區與市北區氣溶膠散射繫數和吸收繫數的變化特徵,結閤同期的相關氣象資料對變化特徵進行瞭討論。結果錶明,市中區和市北區氣溶膠的散射繫數、吸收繫數具有相同的變化趨勢。總體上呈“W”型;峰值分彆齣現在0:00和12:00前後,穀值則齣現在5:00和17:00前後。散射繫數遠大于吸收繫數,說明大氣氣溶膠的消光作用主要由散射作用完成。相對濕度與散射繫數、吸收繫數不具有顯著相關性,而風速對散射繫數、吸收繫數影響較大,且對市北區的影響大于市中區。

We have used integrating nephelometer to observing the scattering and absorption coefficients of the aerosol at the middle area (MA)and north area (NA) of Urumqi, in order to analysis the variation of scattering and absorption coefficients combined with meteorological data of the same period. The results show the same trendency of scattering and absorption coefficent between MA and NA, showing “W” shape. The peak value appeared at 0:00 and 12:00 respectively,however, the valley value showed at 5:00 and 17:00. Scattering coefficient is much larger than the absorption coefficient. Its indicate that the role of extinction of aerosols is mainly depended on scatting. Relative humidity does not have a significant correlation with the scattering absorption coefficient, While the wind speed greater impact on the scattering absorption coefficient.
