本文较详细地介绍了为p-σ五层原始方程模式设计的一个对温度场作整层对流调整的方案。在温度场调整的同时, 湿度场也相应受到调整。此方案的采用避免了该模式过去采用有限层T、q、???的干对流调整方案时所产生的上层的静力不稳定现象, 延长了对方程组的积分期限, 而且模拟的降水率分布也有所改善。

A convective adjustment scheme developed for the p-σ combined vertical coordinate five-layer primitive equation model is presented in detail in this paper. Besides the temperature, the humidity field is also adjusted with this scheme. The use of this scheme has made the avoidance of the hydrostatic unstable which occured in the upper layer when the original limited layer dry convective adjustment scheme for T, q and ??? was used, and allowed us to carry the integration of the model over a much longer period. The simulated distributions of the precipitation rate are also improved.
