Research
Stratocumulus clouds are particularly common in the subtropical regions and cover one-fifth of the Earth's surface. They regulate the climate and create a cooling effect on the surface through the reflection of the incoming solar radiation. Stratocumulus coverage will decrease with the current warming conditions, but how much remains unclear. The strong coupling between metre-scale processes in the cloud-top region, the free troposphere and the SST complicates the projections. Numerical models with insufficient resolution overestimate mixing and mask the sensitivity of stratocumulus to changes in the environmental conditions. How reliable are then these models when used to study the role of stratocumulus in the climate system?
Direct numerical simulations with increased resolution improve the representation of mixing, such that radiation effects can be better accessed. In my research, the microscale model will be coupled with the radiative transfer model to study the effect of water vapour in longwave radiation, as well as the shortwave radiation and the diurnal cycle of stratocumulus.
