Zusammenfassung |
The recent gradual increase in the use of polarimetric radars prompts for
possible improvements in the estimation of precipitation and the
identification of the prevailing hydrometeor type. An analysis of different
convection episodes (20 May 2003, 4 and 7 May 2004) is conducted in order to
explore the attenuation effects at C band and their consequences on the
rainfall field estimation using two polarimetric radars in the Po Valley,
Italy, located about 90 km apart. A hydrometeor classification scheme,
developed at the National Severe Storms Laboratory (NSSL), is used to detect
the microphysical structure of the different cloud systems. The work is
focused on the reconstruction of the 3-D organisation of the convective
events, highlighting how the two radar systems ''see'' the storms from
different points of view. Furthermore, the two distinct observations and the
temperature field are used to correct the effect of attenuation. |
