The results of a detailed analysis of 159 tornado proximity rawinsonde soundings are considered in Part I of this study. An extensive discussion of tornado features and a hypothesized physical model of tornado genesis is presented in Part II of this paper.

VHF wind profiler data were used to study the vertical draft structure within 13 tropical Mesoscale Convective Systems (MCSs) near Darwin, Australia during the wet season of 1989-1990 and 1990-1991.

This study examines the sensitivity of horizontal heterogeneities of the soil moisture initialization (SMI) in the cloud-resolving grid of two real-data mesoscale convective system (MCS) simulations during their genesis phase.

Atmospheric structure derived from satellite, multi-channel radiance data is used to calculate zonally-averaged vertical motions in the wintertime stratosphere of both hemispheres.

This paper discusses one to two day future tropical cyclone intensity change from both a composite and an individual case point-of-view. Tropical cyclones occurring in the Gulf of Mexico during the period 1957-1977 form the primary data source.

A linear theory is given for the case of steady thermal convection in a stratified fluid with a general thermal boundary condition at the upper and lower limits of the system. The theory is applied to a number of fluid systems and the results are discussed in terms of the Rayleigh number, the horizontal wave number and the vertical velocity and temperature perturbation profiles in the vertical.

Observational information from approximately 100 flight missions flown into twenty-one hurricanes on forty-one storm days over a thirteen year period by aircraft of the NOAA's Research Flight Facility is used to present a unified view of the structure, dynamics, and variability of the hurricane's inner core region.
