THE AUGUST STORMS

Severe Local Storms

Knowledge of severe local storms has been increasing rapidly in recent years as a result of both observational studies and numerical modeling experiments. This paper reviews that knowledge as it relates to development of new applications for forecasting of severe local storms. Many of these new applications are based on physical understanding of processes taking place on the storm scale and thu...

Dust Storms: Schwartz's Response

Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...

Lake Effect Snow Storms

Definition: The term “lake effect” generally refers to the effect of any lake in modifying the weather about its shore and for some distance downwind. In the United States, this term is applied specifically to the region about the Great Lakes or the Great Salt Lake. More specifically, lake effect often refers to the generation of sometimes spectacular snowfall amounts to the lee of the Great La...

Of Streams and Storms

The Electric Current-systems of Magnetic Storms

1. This paper continues my discussion of the average characteristics of the field of geomagnetic disturbances or storms, given in two previous papers • which will be referred to as I and 2; the irregular part of magnetic disturbance is not considered. A condensed representation of the main average features of magnetic storms is given in 1 (pp. 61-72) and 2 (pp. 242-264), and evidence is describ...
