| 摘 要： | 利用1979~1992年卫星TOR对流层臭氧数据库资料，以及同期太阳辐照度数据序列，考察青藏高原对流层臭氧含量变化与太阳辐射周期变化之间的关系.分析表明，青藏高原对流层臭氧分布表现出与太阳辐照度相同的变化趋势，存在着明显的太阳周期变化特征.逐月线性回归分析表明，太阳辐照度增加导致青藏高原对流层臭氧增加的正效应.在太阳周期内，太阳辐射增加可使青藏高原对流层臭氧、平流层臭氧和臭氧总量分别增加1.31、4.97、6.628DU，或4.07%、2.04%、2.28%.该特征与赤道太平洋地区完全相反，分析产生差异的原因，至少应包括两方面因素：一是背景大气NOX和水汽含量的差异；二是青藏高原频繁发生的平流层-对流层大气物质交换和输送.

| Abstract: | Tropospheric column ozone data during 1979 to 1992 over the Tibetan Plateau and Solar flux F10.7 index data at the same period, are used to evaluate the relationship between tropospheric ozone variation and solar flux change. It is shown that there exists a solar cycle changing trend in the tropospheric ozone at this region. The estimated changes in tropospheric and stratospheric and column total ozone over a solar cycle are representively 1.31, 4.97 and 6.628 Dobson Units (DU), or 4.07%, 2.04% and 2.28% from solar minimum to solar maximum. This is quite different from that trend over tropic Pacific region discovered by Chandra et al. 1999. In the tropic Pacific region, a negative changing trend was found. There are at least two aspects should be put consideration in explain the difference. One is the different component of NOX and water vapor in the background atmosphere over those two regions. The other is the continually stratosphere-troposphere exchange in the Tibetan Plateau may resulting in some ozone is sent to troposphere from stratosphere. |
