Abstract

Data on the rate of stratospheric ozone destruction in the O_x, HO_x, NO_x, ClO_x, and BrO_x catalytic cycles in the Northern Hemisphere in the latitude range of 10°–80° for December and June 1995 are provided. The data for the calculations are obtained using the SOCRATES interactive two-dimensional radiation and chemical model. The RCP 4.5 scenarios of the Intergovernmental Panel on Climate Change (IPCC) for the weather conditions of December and June 1995 are used as initial conditions. It is shown that the nitric oxide (NO_x), hydrogen (HO_x), and oxygen (O_x) cycles have the largest contribution to the destruction of stratospheric ozone during the period under consideration, and this contribution (as well as the contribution of other cycles) substantially changes with season and altitude.

20世纪末，北半球催化循环中的平流层臭氧破坏

摘要

提供了关于1995年12月和1995年6月北半球10°-80°纬度范围内O _x，HO _x，NO _x，ClO _x和BrO _x催化循环中平流层臭氧破坏速率的数据。计算的数据是使用SOCRATES交互式二维辐射和化学模型获得的。政府间气候变化专门委员会（IPCC）针对1995年12月和6月天气状况的RCP 4.5情景被用作初始条件。结果表明，一氧化氮（NO _x），氢（HO _x）和氧（O _x）周期在上述期间对平流层臭氧破坏的贡献最大，并且该贡献（以及其他周期的贡献）随季节和海拔高度而发生很大变化。
