TURBULENCE AND MICROPHYSICAL RETRIEVALS IN BOUNDARY LAYER CLOUDS USING MM-WAVELENGTH DOPPLER SPECTRA

Due to their short wavelength, millimeter radars are capable of detecting very small droplets. This capability has established them as the ultimate observing systems for the study of weak meteorological targets undetectable by conventional weather radars. In this paper, some new ideas on the use of millimeter wavelength Doppler spectra for the retrieval of turbulence and microphysical parameters are injected in an attempt to emphasize the importance of recording the Doppler spectrum at vertical incidence. In particular, emphasis is given in the retrieval of turbulence intensity at resolvable and non-resolvable radar sampling scales and the removal of turbulence broadening for drizzle size distribution using the Doppler spectrum moments
