This book reviews the principles of Doppler radar and emphasizes the quantitative measurement of meteorological parameters. It illustrates the relation of Doppler radar data and images to atmospherix phenomena such as tornados, microbursts, waves, turbulence, density currents, hurricanes, and lightning. Radar images and photographs of these weather phenomena are included.- Polarimetric measurements and data processing- An updated section on RASS- Wind profilers- Observations with the WSR-88D- An updated treatment of lightning- Turbulence in the planetary boundary layer- A short history of radar- Chapter problem sets
