Jul 01, 2008; Lu, Feng; Zhang, Xiaohu; Xu, Jianmin ... ABSTRACT An automatic image navigation algorithm for Feng Yun 2 (FY2) spin-stabilized geosynchronous meteorological satellites was determined at the National Satellite Meteorological Center (NSMC) of the China Meteorological Administration (CMA). This paper derives the parameters and ...
An Approximation to the Effective Beam Weighting Function for Scanning Meteorological Radars with an Axisymmetric Antenna Pattern
Jul 01, 2008; Blahak, Ulrich ... ABSTRACT To obtain statistically stable reflectivity measurements by meteorological radars, it is common practice to average over several consecutive pulses during which the antenna rotates at a certain angular velocity. Taking into account the antenna's continuous motion, the measured ...

Tornado Detection Using a Neuro-Fuzzy System to Integrate Shear and Spectral Signatures
Jul 01, 2008; Wang, Yadong; Yu, Tian-You; Yeary, Mark; Shapiro, Alan; Nemati, Shamim; Foster, Michael; Andra, David L Jr; Jain, Michael ... ABSTRACT Tornado vortices observed from Doppler radars are often associated with strong azimuthal shear and Doppler spectra that are wide and flattened. The current operational tornado detection algorithm (TDA) primarily searches for shear signatures that are larger than the predefined ...
