Observational Studies of Mesoscale Cellular Convection
Publisher: American Meteorological Society
Abstract: An observational study of mesoscale cellular convection occurring over vast regions of the North Atlantic and North Pacific has been done for the period 1 January 1969 through 30 June 1970. Satellite cloud photography from ...
Latent and Sensible Heat Flux Calculations at the Air-Sea Interface During AMTEX 74
Publisher: American Meteorological Society
Abstract: Computations of latent and sensible heat flux at the air-sea interface using the bulk-aerodynamic method are presented for the period of the 1974 Air Mass Transformation Experiment (AMTEX) conducted over the East China ...
A Model for Investigating Eddy Viscosity Effects on Mesoscale Cellular Convection
Publisher: American Meteorological Society
Abstract: A mathematical model consisting of a complete set of the Boussinesq equations governing Rayleigh convection in the atmosphere has been solved for the marginal stability case in order to study the geometry and circulation ...
Tornado Vortex Simulation at Purdue University
Publisher: American Meteorological Society
Abstract: A 4 m wide and 7 m tall tornado vortex generator (including exhaust fan and duct work) has been constructed at Purdue University that operates on a principle similar to that of the earlier machine modeled by Ward (1972). ...
A Review of Mesoscale Cellular Convection
Publisher: American Meteorological Society
Abstract: A brief review of the classical theory for convective instability is presented, with primary emphasis on the more recent theoretical and experimental findings that pertain to mesoscale cellular convection in the atmosphere. ...
Multiple Vortex Features in the Tornado Cyclone and the Occurrence of Tornado Families
Publisher: American Meteorological Society
Abstract: Analyses are presented of the tornado tracks for four tornado families affecting Indiana and neighboring states on 3 April 1974. The study by Agee et al.(1975)on the occurrence of multiple suction vortices in the tornado ...
A Height-Dependent Model of Eddy Viscosity in the Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: A height-dependent model of the vertical eddy diffusivity for momentum, K(Z), has been formulated for purposes of studying numerically the momentum (and heat) transfer arising from turbulent motions within the planetary ...
Characteristics of Tornado-Like Vortices as a Function of Swirl Ratio: A Laboratory Investigation
Publisher: American Meteorological Society
Abstract: The investigation of tornado vortex dynamics by means of a laboratory simulation is described. Based on observations from nature and an examination of the Navier-Stokes equations, a laboratory simulator of the Ward type ...
An Observational Study of the West Lafayette, Indiana, Tornado of 20 March 1976
Publisher: American Meteorological Society
Abstract: An observational study of the West Lafayette, Ind., tornado of 20 March 1976 has been made that presents photographic evidence of tornado formation accompanied by suction ?debris? vortices in the surface boundary layer ...
