precipitation growth in cold clouds o r T he importance of the lower boundary Qun Miao Ningbo University Bart Geerts University of Wyoming NCAR orographic precip workshop 1315 March 2012. . 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. . Convection in the boundary layer occurs to transport heat moisture, and momentum from surface to free atmosphere. Two common scenarios:. 1) Daytime solar heating 2) cold-air outbreaks, lake effect.

In a flow, the boundary layer represents a (relatively) thin layer of fluid that is nearest the solid boundary. 87-351 Fluid Mechanics. [ physical interpretation: what are we doing today? ].

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. . 3- Buoyant . Production/Consumption . Production. Term .
