A linear diagnostic equation for the nonhydrostatic vertical motionW in severe storms

  • Yuan Zhuojian

A linear diagnostic equation for the nonhydrostatic vertical motionW in severe storms is derived in the Cartesian-earth-spherical coordinates. ThisW diagnostic equation reveals explicitly how forcing factors work together to exert influence on the nonhydrostatic vertical motion in severe storms. If high-resolution global data are available in Cartesian coordinates with guaranteed quality, the Lax-Crank-Nicolson scheme and the Thomas algorithm might provide a promising numerical solution of this diagnostic equation. As a result, quantitative analyses are expected for the evolution mechanisms of severe storms.
