PPT-Modification of a Mesoscale Model Planetary Boundary Layer

David E Jahn WESEP594 Fall 2013 Wind Energy Science Engineering and Policy WESEP Program Iowa State University Background With continued increase in wind power integration as part of the US electric grid wind variability is of concern. Stephen Rodriguez, Jr.. National Weather Service Chicago, IL. Introduction. Brief background.. Purpose of Study.. Synoptic background and forcing mechanisms.. Synoptic/. Mesoscale. features: Moisture, Forcing, Instability.. . Drag force. The surrounding fluid exerts pressure forces and viscous forces on an object. .. The components of the resultant force acting on the object immersed in the fluid are the drag force and the lift force. . Logan Dougherty. Quick Overview.

About a half . -. hour before sunset the thermals cease to form (in the absence of cold air advection), allowing turbulence to decay in the formerly well-mixed layer. The resulting layer of air is sometimes called the residual layer. .
