Daytime convective development over land: The role of surface forcing

Professor Wojciech W. Grabowski  from NCAR conducted a seminar to present their article Daytime convective development over land: The role of surface forcing. Recently published at the Quarterly Journal of the Royal Meteorological Society. 

The article explores how water availability at the Earth’s surface influences the partitioning of surface heat flux into sensible and latent components, which in turn affects the development and growth of the convective boundary layer and daytime convection over land. Through the use of two canonical modeling test cases (one for shallow convection and one for the shallow-to-deep convection transition), the study documents the impact of the surface Bowen ratio on daytime convection development, influence of lower-tropospheric shear, and proposes that wider clouds in deeper boundary layers are due to larger coherent structures within the boundary layer itself. 

The seminar was in hybrid mode on Zoom and  at the University of Hyogo, Kobe Campus for Information Science, Computational Science Center Building. And over 35 participant attended the event.
