The UM-UKCA (Unified Model coupled to the United Kingdom Chemistry and Aerosol module) global chemistry-climate model includes a parameterisation scheme describing stratospheric mountain-wave-induced temperature fluctuations, which is coupled to the models PSC scheme. Novel developments such as this that make interactive chemistry-climate models more physically based and comprehensive are needed to improve our ability to make accurate predictions of stratospheric ozone and reduce uncertainties in the current and future climate. The model will be used to understand the sensitivity of projections of twenty-first century stratospheric polar ozone levels and climate in both hemispheres to inclusion of realistic representation of PSCs, and especially whether the timing of the recovery of the Antarctic ozone hole (and its role in offsetting the effects of increasing greenhouse gases) is affected. The project will involve close collaboration with an ongoing complementary project between BAS, NASA, and other international partners.

UM-UKCA（统一模型与英国化学和气溶胶模块结合）全球化学气候模型包括一个参数化方案，描述了平流层山波诱导的温度波动，并耦合到模型PSC方案。诸如此类的新型发展使交互式化学气候模型更基于身体和全面，以提高我们对平流层臭氧的准确预测并减少当前和未来气候下的不确定性的能力。该模型将用于了解两个半球的二十一世纪平流层臭氧水平和气候的投影的敏感性，对包括现实的PSC表示，尤其是南极臭氧孔的恢复时间（及其在抵消增加的温室气体效应中的作用）是否受到影响）。该项目将涉及与BAS，NASA和其他国际合作伙伴之间正在进行的互补项目密切合作。
