中文摘要:

在这研究, TOMS/SBUV (全部的臭氧印射 Spectrometer/Solar 反散射紫外辐射计) 数据和半自动地面防空系统(同温层的喷雾器和煤气的实验) II 数据被采用在西藏的高原和 15050-hPa 上计算每月全部的带的臭氧偏差带的臭氧变化。结果证明在之间有重要关联二,与 0.977 的一个关联系数。从 150~50 hPa ,在西藏的高原( OVTP )上的臭氧山谷高基于 SAGE II 数据,和南方亚洲人变得最强壮( SAH )根据中等范围的天气预报( ERA40 )的欧洲中心的40年的分析数据是最活跃的,在 SAH 和 OVTP 之间的关联可以因此存在。WACCM3 (整个空气社区气候模型版本 3 ) 甚至当西藏的高原的高度被砍倒到 1500 m 时, SAH 和 OVTP 能仍然在 15050 hPa 以内介绍与的模拟结果表演减少了力量。SAH 的季节的变化将导致 OVTP 的一个匹配的季节的变化,这也被显示出,它在 OVTP 上建议 SAH 的有意义的效果。同时,大气的发行量将在 OVTP 上强加不同效果,这被发现,取决于 SAH 进化阶段和运动方向。在 15050 hPa,当 SAH 接近高原, SAH 带(南方) 运输将使 OVTP 更深(更浅) ,当臭氧的垂直运输生产时一更深(更浅) OVTP 在更低(更高) 水平;联合动态效果导致削弱的 OVTP。当 SAH 在高原上稳定时,带(南方) 运输结果在一更浅(更深) OVTP 当垂直运输将创造时一更深(更浅) 在中间(底部和顶) 的 OVTP 铺平;联合动态效果生产更深的 OVTP。作为从高原的 SAH 撤退, OVTP 变得更深(更浅) 在下面带(南方) 效果或在垂直效果下面更浅;联合动态效果贡献一更深(更浅) 在中间(底部和顶) 的 OVTP 铺平。当在热带太平洋上放了时, SAH 将在高原上在 OVTP 上有弱效果。

英文摘要:

In this study,the TOMS/SBUV(Total Ozone Mapping Spectrometer/Solar Backscatter Ultraviolet Radiometer) data and SAGE(Stratospheric Aerosol and Gas Experiment) II data were employed to calculate the monthly total zonal ozone deviations over the Tibetan Plateau and the 150-50-hPa zonal ozone variations.The results show that there is a significant correlation between the two,with a correlation coefficient of 0.977.From 150 to 50 hPa,the ozone valley over the Tibetan Plateau(OVTP) becomes the strongest based on the SAGE II data,and the South Asian high(SAH) is the most active according to the 40-yr reanalysis data of the European Centre for Medium-Range Weather Forecasts(ERA40),so a correlation between the SAH and the OVTP may exist.The WACCM3(Whole Atmosphere Community Climate Model version 3) simulation results show that both SAH and OVTP could still present within 150-50 hPa with reduced strength even when the height of the Tibetan Plateau was cut down to 1500 m.It is also shown that the seasonal variation of SAH would result in a matched seasonal variation of the OVTP,which suggests a meaningful effect of SAH on the OVTP.Meanwhile,it is found that the atmospheric circulation would impose different effects on the OVTP,depending on the SAH's evolution stages and movement directions.At 150-50 hPa,as the SAH approaches the plateau,the SAH zonal(meridional) transport would make the OVTP deeper(shallower),while the vertical transport of ozone produces a deeper(shallower) OVTP at the lower(higher) level;the combined dynamic effects lead to a weakened OVTP.When the SAH stabilizes over the plateau,the zonal(meridional) transport results in a shallower(deeper) OVTP while the vertical transport would create a deeper(shallower) OVTP at the middle(bottom and top) levels;the combined dynamic effects produce a deeper OVTP.As the SAH retreats from the plateau,the OVTP becomes deeper(shallower) under the zonal(meridional) effect or shallower under the vertical effe
