Abstract: The generalized Ekman equation is often used for micrometeorological applications. Use of the noniterative numerical technique of superposition reveals that the vertical variation of both the eddy diffusivity and the thermal ...

Abstract: A dryline is a narrow zone, other than a classical polar front, across which a sharp horizontal surface moisture gradient occurs. It often exists and moves under synoptically quiescent conditions. One explanation of dryline ...

Abstract: Nonlinear biconstituent diffusion is proposed as a possible trigger for cumulus development. Properties of this second-order effect are examined. It is shown that this process can exist in the atmosphere and that it can ...

Abstract: Techniques that have evolved during the hundred years that scientific severe thunderstorm forecasts have been prepared are reviewed. The early empirical rules developed by Finley, Showalter and Fulks, Fawbush, Miller and ...

Abstract: A form of the critical success index (CSI) is used by the National Weather Service to indicate the value of warnings. This verification statistic assumes that the times when an event was neither expected nor observed are ...

Abstract: The dryline, a narrow non-frontal zone of sharp moisture discontinuity, has long been known as a preferential location of thunderstorm development. Through an examination of several years of data, a conceptual model of the ...

Abstract: The correlation between tornadic activity in several regions of the United States and the monthly mean sea surface temperature over four zones in the tropical Pacific Ocean is examined. Tornadic activity is gauged with two ...
