Abstract: The results from three methods for studying transport and dispersion in cumuli are compared. These three methods include two tracer techniques and a numerical simulation. The tracers, SF6 and radar chaff, were simultaneously ...

Abstract: Mesoscale to synoptic-scale squall lines that form along the northeastern coast of South America as sea-breeze-induced instability lines and propagate through the Amazon Basin are investigated using data collected during ...

Abstract: The column response to propagating deep convection over the central Amazon Basin is investigated with rawinsonde data from the Amazon Boundary Layer Experiment (ABLE 2B). Heat and moisture budgets are calculated from a ...

Abstract: Theoretical studies, aircraft, and space-borne measurements show that deep convection can be an effective conduit for introducing reactive surface pollutants into the free troposphere. The chemical consequences of convective ...

Abstract: In July and August 1985, and April and May 1987, two atmospheric chemistry field experiments called the Amazon Boundary-layer Experiments, (ABLE 2A and 2B) were conducted from a base near Manaus, Brazil in the central ...

Abstract: A severe 5?day lake?effect storm resulted in eight deaths, hundreds of injuries, and over $3 million in damage to a small area of northeastern Ohio and northwestern Pennsylvania in November 1996. In 1999, a blizzard ...
