The March Storms

Forecasting severe ice storms using numerical weather prediction: the March 2010 Newfoundland event

The northeast coast of North America is frequently hit by severe ice storms. These freezing rain events can produce large ice accretions that damage structures, frequently power transmission and distribution infrastructure. For this reason, it is highly desirable to model and forecast such icing events, so that the consequent damages can be prevented or mitigated. The case study presented in th...

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...
