TL;DR: The piecewise parabolic method (PPM) as discussed by the authors is a finite volume scheme that represents physical variables as averages over a grid zone rather than single values at discrete points, and each zone boundary is treated as a discontinuity.

TL;DR: In this paper, the authors present analyses of data collected in the vicinity of a cloud-free dryline that occurred in western Oklahoma on 24 May 1989, showing that the environment of the 24 May dryline is dominated by vertical mixing that maintains a convective boundary layer (CBL) on both sides of the dryline.

TL;DR: In this article, the authors investigated the reasons for initiation of long-lived thunderstorms along the dryline in northwestern Oklahoma during the afternoon of 26 May 1991 by analyzing observations collected during the Cooperative Oklahoma Profiler Studies-1991 field program.

TL;DR: In the spring of 1991 experiments were carried out to study the dry line and convective storms near the dryline as part of the Cooperative Oklahoma Profiler Studies program, which was supported by the National Oceanic and Atmospheric Administration, the National Science Foundation, and the National Aeronautics and Space Administration as discussed by the authors.

TL;DR: In this paper, a method for retrieval of pressure and buoyancy distributions in deep convection is applied to Doppler radar data collected at two analysis times during the tornadic Del City (Oklahoma) thunderstorm of 20 May 1977.
