Abstract: Diagnostic case studies of ageostrophic circulations in upper-tropospheric jet-front systems are presented, using the numerical analyses of the ECMWF model as data sources. The impact of the ECMWF analysis procedure on the ...

Abstract: A stratocumulus cloud located above a cold front in a midlatitude depression has been observed simultaneously by a K-band radar, instrumented aircraft and radiosondes. The radar recording suggests that convective generating ...

Abstract: Multiple parameter radar measurements (dual frequency hail signal DFR-HS or differential reflectivity ZDR) can be strongly affected by the mismatch of the antenna illumination functions at the two wavelengths or polarizations. ...
