Abstract: Various features of the radar echo from a severe local storm are interpreted with the purpose of defining the nature of its updraft. The analysis illustrates the methodology of using conventional radar data to study airflow ...

Abstract: A life cycle classification for severe local storms is proposed, which adds a fourth stage, the quasi-steady SR Mature Stage, to the well-known Byers-Braham classification. A combined analysis of the surface weather and ...

Abstract: A kinematic airflow model is proposed for severe local storms which travel to the right of the winds in the middle troposphere. The model is an extension of that proposed by Browning and Ludlam (1962), and represents an ...

Abstract: Imagery from radars and satellites is one of the main ingredients of nowcasting. When used to provide very detailed forecasts of precipitation for a few hours ahead, the imagery needs to be interpreted carefully in terms ...

Abstract: The origin of a severe local storm is traced back to a cluster of three shower cells, each of which produced a fist radar echo close to the ?30C level. This level is much higher than that associated with the majority of ...

Abstract: The nature of the targets responsible for certain clear-air dot angel echoes, and their suitability as wind tracers, are deduced from pulse Doppler radar observations of their velocity characteristics. The angel echoes ...

Abstract: Wind tunnel test data on the relationship between drag coefficient and Reynolds number are presented for solid spherical models with different roughness parameters. Using a wind tunnel with minimal free-stream turbulence ...
