The simulations are based on a recent paper by Weisman and Rotunno, who argue that low-level shear has a "profound effect" on system organization. They also argue for an "optimal state," wherein some system properties such as surface wind speed are maximized. We evaluate whether our numerical model simulations support these conclusions.
This intercomparison also facilitates the discovery of biases that may exist in the numerical models. One notable result is that the Klemp-Wilhelmson model tends to produce deeper, colder surface-based cold pools. The reason for this difference, and its implications on the theory advanced by Weisman and Rotunno, are discussed.
