Abstract: The sufficient condition for inviscid, helical instability at large wavenumbers is applied to solutions for columnar vortices arising from the vortical flow of an end-wall boundary layer. The end-wall vortex arising from ...

Abstract: A three-dimensional, anelastic wind field on a staggered grid, with a specified normal wind component on the lateral boundaries, can be reversibly transformed into two scalar fields. In a conformal, terrain-following ...

Abstract: A one-dimensional numerical model KOLUM is introduced that demonstrates the use of continuous dynamic grid adaption in modeling the atmospheric boundary layer. The entrainment rates of KOLUM are compared against recent ...

Abstract: An integral closure model is proposed for the vertical turbulent transport of a scalar in a mixed layer. The flux divergences at a given level is related to a vertical integral of a weighting function multiplied by the ...

Abstract: We have developed a physical theory for the finding that the most intense laboratory vortex occurs when it is in the form of an end-wall vortex. We argue that the end-wall vortex allows no standing centrifugal waves (i.e., ...

Abstract: A novel approach to the modeling of tornado-like vortexgenesis has been developed and is used to articulate the sequence of events that leads to tornadogenesis. The ?pseudostorm? is an idealized thunderstorm representation ...

Abstract: The previously developed two-layer model of cold air damming is extended to include upstream cold air inflow. The upper layer is an isentropic cross-mountain flow. The lower layer is a cold boundary layer flow partially ...

Abstract: A closure scheme is developed for representing the mean vertical transport of a passive scalar within a convective boundary layer. The scheme predicts the evolution of the mean vertical profiles toward the form of the ...
