Abstract: Formulas are derived, and their characteristics examined, for the purpose of optimizing objectively contoured patterns of air pollution concentrations where the diffusion equation is used as a dynamical constraint in the ...

Abstract: A method is proposed whereby the Sutton-type diffusion coefficients appropriate for the instantaneous source may be estimated from observations of dissipation times for smoke puffs generated by standard gunpowder charges. ...

Abstract: The effect on instantaneous source diffusion of initial source size and diffusing time are studied from observations on the rate of separation of pairs of ?zero lift? balloons. The data indicate that the similarity concept ...

Abstract: Experimental data and theory suggest that certain convection cell scale factors must be specified for correct interpretation of tornado simulations. The most important nondimensional number appears to be the ratio of ...

Abstract: A simulation of tornadoes translating over the ground was carried out in a modified Ward simulator. The purpose was to investigate the effects of translation on tornado dynamics. The results are as follows: ? Secondary ...

Abstract: Individual thermals rising through the atmosphere may encounter the wake of one or more thermals that started their rise at an earlier time. Laboratory simulations show that the growth rate of second and third thermals in ...
