“对流和地形诱发降水研究”（COPS）分析了复杂地形上驱动深层对流的过程。对流起始（CI）主要不是由单一过程来表达，而是由多种过程来表达，这些过程在时间和空间的不同尺度上相互作用，最终导致深层对流。本文介绍了对不均匀地形上这种情况的研究。来自 COPS 站点网络的数据被用来识别 CI 的时间和位置。在许多情况下，这与最初的对流云、阵雨甚至雷暴的地点并不相同。结果表明，局部多尺度的 CI 过程的相互作用会导致深对流和强风暴或平静的天气。不同结果之间的边界条件很窄。
The ‘Convective and Orographically‐induced Precipitation Study’ (COPS) analyses the processes driving deep convection over complex terrain. Convection initiation (CI) is mainly not only expressed by a single process, but by a variety of them, which interact on different scales in time and space and finally can lead to deep convection. A study of such a case over inhomogeneous terrain is presented in this article. Data from the COPS network of stations are taken to identify the time and location of CI. In many cases this is not the same location as the first convective clouds, showers or even thunderstorms. It is shown that the interaction of the CI processes on multiple scales locally leads to either deep convection and severe storms or calm weather. The boundary conditions between the different outcomes are narrow.
