A Mesoscale Investigation of Convective Activity.
Abstract
A mesoscale investigation of a series of tornadoes and thunderstorms that passed through the NSSL mesonetwork in Oklahoma, on 10 June 1967, between 1700 and 2300 CST, was conducted. Utilizing upper air data provided by NSSL, the divergence, vertical motion, and energy fields were computed. A finite-difference technique for computing and smoothing divergence was developed. The vertical motion was then computed by means of the kinematic method. Both the total derivative and the local rate of change of static energy were computed. Using the values of the local rate of change, prognostic fields of static energy and an energy index were obtained. Finally, forecast energy indexes, divergence, and vertical motion fields were compared to the observed locations of tornadoes and thunderstorms. (Author)
