摘要:

本文發(fā)展了一個(gè)耦合的城市邊界層-湖泊模式(RBLM-Chem-Lake),通過離線和在線兩種方式對模式的模擬效果進(jìn)行了檢驗(yàn)。并通過敏感性實(shí)驗(yàn)分析了太湖冬季和夏季對周邊地區(qū)氣象特征和空氣污染的影響。結(jié)果表明:(1)白天太湖對周邊氣象環(huán)境產(chǎn)生了明顯的降溫效應(yīng),而夜晚出現(xiàn)了明顯的升溫。冬季夜晚周邊地區(qū)升溫達(dá)到0.4~0.6℃,白天可以使得周邊氣溫降低1~2℃。夏季夜晚使周邊地區(qū)升溫可達(dá)1~1.5℃,白天使得周邊氣溫降低1~2℃。(2)太湖對周邊地區(qū)氣溫的影響范圍夏季遠(yuǎn)高于冬季,夏季影響范圍可達(dá)到80 km,冬季影響范圍平均為5 km。此外,太湖使得湖區(qū)平均邊界層高度下降,濕度上升,使得蘇州市區(qū)垂直風(fēng)速減弱,這種影響同樣在夏季更為明顯。(3)太湖的存在總體上使湖區(qū)和周邊地區(qū)PM_2.5和臭氧的質(zhì)量濃度增加。在冬季PM_2.5污染個(gè)例中,太湖導(dǎo)致區(qū)域夜晚PM_2.5質(zhì)量濃度下降,下降幅度達(dá)到4~5μg·m^-3。而在白天,太湖區(qū)域500 m高度以下PM_2.5質(zhì)量濃度增加,幅度達(dá)到25~30μg·m^-3,在500 m高度以上質(zhì)量濃度下降約5~10μg·m^-3。夏季的臭氧污染日個(gè)例中,白天,在太湖的東岸以及蘇州市區(qū)臭氧的質(zhì)量濃度出現(xiàn)了明顯的增加,可以達(dá)到10~12μg·m^-3。

Abstract:

This article has developd a coupled urban boundary layer lake model (RBLM-Chem-Lake) and verified its simulation effect through both offline and online ways.Through sensitivity experiments,the impacts of the Lake Taihu on meteorological characteristics and air pollution in surrounding areas in winter and summer were analyzed.Results show that:(1) in the daytime,the Lake Taihu has an obvious cooling effect on the surrounding meteorological environment,while at night,an obvious warming occurs.In winter,the temperature in the surrounding area rises to 0.4-0.6℃ at night,while during the day,it can reduce the temperature by 1-2℃.Summer nights can increase the temperature in the surrounding areas by up to 1-1.5℃,while in the daytime,it can lower the temperature by 1-2℃.(2) The influence range of the Lake Taihu on the temperature in the surrounding areas is much higher in summer than that in winter.The influence range can reach 80 km in summer but 5 km in winter on average.In addition,the Lake Taihu reduces the average boundary layer height in the lake area and increases the humidity,which weakens the vertical wind speed in Suzhou urban area.This effect is also more obvious in summer.(3) The presence of the Lake Taihu generally increases the concentration of PM_2.5 and ozone in the lake area and surrounding areas.In the case of PM_2.5 pollution in winter,the Lake Taihu leads to the decrease of PM_2.5 concentration at night in the lake area by 4-5 μg·m^-3.In the daytime,PM_2.5 concentration in the Lake area below 500 m increases by 25-30 μg·m^-3,and the concentration decreases by about 5-10 μg ·m^-3 above 500 m.In the case of ozone pollution day in summer,the ozone concentration in the east bank of the Lake Taihu and the urban area of Suzhou during the daytime increases significantly,reaching 10-12 μg·m^-3.
