Abstract: Dynamic and thermodynamic fields from ECMWF analyses have been presented for the tropical north African region for July 1989. Except for the region equatorward of 10°N, it has been shown that the pattern of mean low-level ...

Abstract: A dry baroclinic spectral model is used to study the initation of frontal cyclones in a baroclinic life cycle. The mature cyclone exhibits a frontal cyclone development associated with a finite amplitude interaction between ...

Abstract: A case of Saharan cyclogenesis associated with the equatorward intrusion of a trough at the end of the Atlantic storm track is investigated. It is shown that a potential vorticity anomaly resulting from a baroclinic wave ...

Abstract: This paper provides for the first time an objective short-term (8 yr) climatology of African convective weather systems based on satellite imagery. Eight years of infrared International Satellite Cloud Climatology ...

Abstract: Data from four recent reanalysis projects [ECMWF, NCEP?NCAR, NCEP?Department of Energy (DOE), NASA] have been diagnosed at the scale of synoptic weather systems using an objective feature tracking method. The tracking ...

Abstract: Scientific background and motivation for the JET2000 aircraft observing campaign that took place in West Africa during the last week of August 2000 are presented. The Met Research Flight C130 aircraft made two flights along ...

Abstract: The New York State Mesonet (NYSM) is a network of 126 standard environmental monitoring stations deployed statewide with an average spacing of 27 km. The primary goal of the NYSM is to provide high-quality weather data at ...

Abstract: he Observing System Research and Predictability Experiment (THORPEX) was a 10-yr, international research program organized by the World Meteorological Organization?s World Weather Research Program. THORPEX was motivated ...
