A mathematical scheme is developed to compute the gradients of observations taken over complex terrain. The method is applied to an artificial example to demonstrate the scheme. An application is made to surface pressure observations between Little R

The South Dakota School of Mines and Technology armored T-28 airplane has been used to collect electric field data inside thunderstorms since 1986. However, the derivation of the Ex field component in the flight direction has been problematic, and th

A two-dimensional, time-dependent cloud model has been used in two field projects to forecast the convective development during the day from the morning sounding. In effect, the cloud model gives a dynamic analysis of the sounding as affected by heat

The fields of motion within a small, strongly sheared High Plains thunderstrom are examined using measurements of reflectivity and velocity from an airborne Doppler radar and other in situ measurements. The measurements are complemented by a high res

Observations made by three instrumented aircraft, a Doppler radar, and other data sources were used to follow the initiation and development of precipitation in a small cumulus congestus cloud. The cloud was seeded at its base using an airborne silve

A HIPLEX- A cloud case has been used to describe the effects of ice-phase cloud seeding on a cold base cloud. The cast was used at the First International Cloud Modeling Workshop/Conference held in 1985 in Irsee, Federal Republic of Germany, to provi

A two-dimensional, time-dependent model has been developed which gives realistic simulations of many severe storm processes—such as heavy rains, hail and strong winds. The model is a set of partial differential equations describing time changes of

Equations for deducing the vertical motion of air based on aircraft measurements are presented along with derivations. The equations are based on the aircraft equations of motion, but due to different assumptions, the resulting equations are quite di

Direct methods for solving the discrete Poisson equation on various types of regions are generally computationally faster than popular iterative techniques, but this depends somewhat on the initial solution provided the iterative method. If the regio
