| Zusammenfassung |
| During the period 1996–2000, forty-three heavy rainfall events have been
detected in the Internal Basins of Catalonia (Northeastern of Spain). Most
of these events caused floods and serious damage. This high number leads to
the need for a methodology to classify them, on the basis of their surface
rainfall distribution, their internal organization and their physical
features. The aim of this paper is to show a methodology to analyze systematically
the convective structures responsible of those heavy rainfall events on the basis
of the information supplied by the meteorological radar. The proposed
methodology is as follows. Firstly, the rainfall intensity and the
surface rainfall pattern are analyzed on the basis of the raingauge data. Secondly,
the convective structures at the lowest level are identified and characterized
by using a 2-D algorithm, and the convective cells are identified by using a
3-D procedure that looks for the reflectivity cores in every radar volume.
Thirdly, the convective cells (3-D) are associated with the 2-D structures
(convective rainfall areas). This methodology has been applied to the 43 heavy
rainfall events using the meteorological radar located near
Barcelona and the SAIH automatic raingauge network. |
