This book is designed to represent subtropical marine stratus and stratocumulus (MSC) and surface winds in a simple but physical consistent way, which has applications in climate modeling and offshore wind energy development. A simple low cloud cover scheme is developed in Chapter 2, in which the variation of MSC is formulated by connecting low cloud amount with lower tropospheric stability (LTS), large-scale subsidence, and dynamical transport of available dry inhibition energy below trade wind inversion. The new scheme produces realistic seasonal and inter-annual variations of MSC amounts...
