Note: HRES and Ensemble Control Forecast are scientifically, structurally and computationally identical. With effect from Cy49r1, Ensemble Control Forecast output is equivalent to HRES output where shown in the diagrams. At the time of the diagrams, HRES had resolution of 9km and ensemble members had a resolution of 18km.

Fig9.1-4: An example of low stratocumulus not captured by ensemble control (ex HRES). The cloud layer is thin - thin enough to show Kármán vortices. Ensemble vertical profiles reveal that none of the ensemble members managed to create low clouds although all are close to saturation (see vertical profile). Nevertheless, the forecast of cloud, thin or not, can have a large effect on insolation and radiative cooling.
