Lateral mixing in shallow cumulus convection

Cumulus clouds originate by the rise of relatively warmand light air through convection. During the rise, the air cools and cloud droplets are formed by condensation. This thesis mainly concerns small shallow cumulus clouds that produce no, or almost no, precipitation and that we associate with calm, nice weather. Therefore, it might come as a surprise that these clouds still play an important role in weather and climate, not only on a local but even on a global scale. This is not only due to the impact on radiation, but even more by the vertical transport of heat, humidity and wind by these cumulus clouds. Hence, an adequate representation of these cumulus clouds in weather and climate models is key....
