[1] 使用地球探测器总臭氧测绘光谱仪 (EP_TOMS) 1996 年 8 月至 2002 年 7 月的臭氧数据，研究了亚热带西太平洋地区的臭氧逐年变化，特别是 1996/1997 年、1998/1999 年和 2001/2002 年冬季的臭氧低值。回归分析表明，动态信号，例如准两年一次的振荡在确定臭氧总量变化中发挥着重要作用。助推化学输运模型（CTM）用于模拟逐年臭氧变化，并解释在臭氧三维分布中产生臭氧低值的机制。 CTM 是利用气候系统研究中心/国家环境研究所 (CCSR/NIES) 大气环流模型开发的，并引入了温度和水平风速的微移过程。该模型很好地模拟了臭氧的逐年变化，特别是冬季臭氧低值，排除了南纬45°和北纬45°之间的非均质反应过程。结果表明，臭氧的逐年变化主要受动力传输过程控制。
[1] The year-to-year ozone variation over the subtropical western Pacific region is studied, especially the ozone lows in the 1996/1997, 1998/1999, and 2001/2002 winters, using the Earth Probe Total Ozone Mapping Spectrometer (EP_TOMS) ozone data from August 1996 to July 2002. Regression analyses show that dynamical signals, such as the quasi-biennial oscillation, play an important role in determining total ozone variation. A nudging chemical transport model (CTM) is used to simulate the year-to-year ozone variation and explain the mechanism for producing ozone lows in a three-dimensional distribution of ozone. The CTM was developed using the Center for Climate System Research/National Institute for Environmental Studies (CCSR/NIES) atmospheric general circulation model and introducing a nudging process for temperature and horizontal wind velocity. The year-to-year ozone variation, especially the winter ozone low, is well simulated by the model excluding heterogeneous reaction processes between 45°S and 45°N latitude. Results show that the year-to-year ozone variation is mainly controlled by dynamical transport processes.
