| Zusammenfassung |
| A spatial characterization of mid-latitude mesoscale
rain fields from C-band radar measurements is performed by means of a
systematic analysis and modelling of convective raincell shapes. To this aim
a large rainfall dataset, derived from an operational C-band dual-polarized
radar, has been continuously collected from 1996 to 1999. The radar-derived
rain fields consist of 1558 grids of 256×256 km2 with a spatial
resolution of 1 km. A new accurate and adaptive algorithm for raincell
identification is introduced and thoroughly discussed. From this analysis, a
quality-controlled set of 2601 raincells, together with the radial rain
intensities (or raincell horizontal profiles), is extracted. Three
one-dimensional analytical models of rainfall horizontal profile are
reviewed and tested by best fitting their parameters against estimated
raincell data. The statistical results of this intercomparison are
quantitatively analyzed and discussed in terms of mean rainfall horizontal
profiles and root mean square errors. |
