Abstract: First results derived from an NSSL effort to develop a real-time Plan Position Indicator (PPI) display of Doppler isotachs are described. The mean Doppler velocity is estimated for multiple range locations by measuring the ...

Abstract: In this note we propose a technique to uncouple the tie between unambiguous Doppler velocity and range. Transmission of orthogonally polarized waves in pairs of pulses increases a weather Doppler radar's capability to ...

Abstract: Data show that Doppler shift of storm echoes and the range extent of severe storm systems encompass a span exceeding the unambiguous resolving capability of centimetric radars. Echo coherency which is related to Doppler ...

Abstract: On 20 April 1974 a tornadic storm passed between the two NSSL Doppler radars spaced about 42 km apart. Both radars simultaneously collected Doppler data throughout the storm. Air motions synthesized from these data provide ...
