Abstract: The life cycle and interactions of a series of convective systems that developed in northeastern Spain during the afternoon of 7 August 1996 are examined based on remote sensing products, surface observations, and numerical ...

Abstract: A flow where the pressure gradient, Coriolis and viscous forces are balanced is examined. It is found that such a flow is a reasonable approximation to the ?steady state? flow in the vicinity of the contact layer. Kinematic ...

Abstract: A set of mesoscale numerical simulations using the Pennsylvania State University?National Center for Atmospheric Research model is used to investigate two cases of extreme precipitation over eastern Spain. Both cases (3?4 ...

Abstract: Wind fields derived from a network of three VHF Doppler radars are used to calculate the mean kinematic properties of the wind field over Colorado and an area-averaged geostrophic and ageostrophic wind. A numerical technique ...

Abstract: The notion of an ?outbreak? of severe weather has been used for decades, but has never been formally defined. There are many different criteria by which outbreaks can be defined based on severe weather occurrence data, and ...

Abstract: Careful screening of the National Severe Storms Forecast Center's tornado log eliminated almost 20% of the reports as doubtful, leaving 17 659 tornadoes during 27 years, 1950?76 (654 annually). Newspaper accounts and other ...

Abstract: Among the many natural disasters that disrupt human and industrial activity in the United States each year, including tornadoes, hurricanes, extreme temperatures, and lightning, floods are among the most devastating and ...
