抽象的。在这篇文章中，我们记录了“SOCOL”，一个新的化学-气候模型，它已经移植到普通的PC上，并显示出良好的挂钟性能。对模式结果与从观测和同化数据集获得的现代气候数据进行的广泛验证表明，模式相当准确地描述了1990年代后期的大气气候状态。该模式只在平流层上层和高纬度对流层顶附近有明显的温度偏差。后者是模式在对流层顶附近垂直分辨率较低的结果。前者可以归因于对中层大气辐射加热的粗略描述。模拟和观测的热带平流层结构与极涡强度之间的联系的比较表明，总的来说，观测和模拟都表明，理论研究预测的极地夜间急流(PNJ)较强、Brewer-Dobson环流较慢的情况下，低热带平流层的温度和臭氧混合比较高。
Abstract. In this paper we document "SOCOL", a new chemistry-climate model, which has been ported for regular PCs and shows good wall-clock performance. An extensive validation of the model results against present-day climate data obtained from observations and assimilation data sets shows that the model describes the climatological state of the atmosphere for the late 1990s with reasonable accuracy. The model has a significant temperature bias only in the upper stratosphere and near the tropopause at high latitudes. The latter is the result of the rather low vertical resolution of the model near the tropopause. The former can be attributed to a crude representation of radiation heating in the middle atmosphere. A comparison of the simulated and observed link between the tropical stratospheric structure and the strength of the polar vortex shows that in general, both observations and simulations reveal a higher temperature and ozone mixing ratio in the lower tropical stratosphere for the case with stronger Polar night jet (PNJ) and slower Brewer-Dobson circulation as predicted by theoretical studies.
