2007年8月12日，在对流和地形诱导降水研究（COPS）期间进行的多普勒车载雷达观测表明，降水云只在北方黑森林的南北方向的Murg和Nagold山谷之间发展。云层产生了中等程度的降水。天气研究和预报模式在内部区域以700米的水平分辨率运行，能够模拟降水的位置。因此，洞察力的物理机制负责的对流的启动和发展。由热驱动流产生的辐合线限制了在升高表面加热产生的温暖和潮湿的核心内对流的初始位置。最大的降水是由二次对流产生的，二次对流是在冷池流出和热流之间的边界处的核心内开始的。皇家气象学会
Doppler‐On‐Wheels radar observations made during the Convective and Orographically‐induced Precipitation Study (COPS) on 12 August 2007 showed that precipitating clouds only developed between the north–south orientated Murg and Nagold Valleys of the northern Black Forest. The clouds produced moderate precipitation. The Weather Research and Forecasting (WRF) model run at 700 m horizontal resolution in the inner domain was able to simulate the location of the precipitation. Insight is therefore gained into the physical mechanisms responsible for the initiation and development of the convection. Convergence lines resulting from thermally driven flows constrained the initial location of the convection within warm and moist cores produced by heating on elevated surfaces. The heaviest precipitation was later produced by secondary convection, which was initiated within the cores at the boundary between cold‐pool outflows and thermal flows.
