| Zusammenfassung |
| The 10 June 2000 event was the largest flash flood event that occurred in
the Northeast of Spain in the late 20th century, both as regards its
meteorological features and its considerable social impact. This paper
focuses on analysis of the structures that produced the heavy rainfalls,
especially from the point of view of meteorological radar. Due to the fact
that this case is a good example of a Mediterranean flash flood event, a
final objective of this paper is to undertake a description of the evolution
of the rainfall structure that would be sufficiently clear to be understood
at an interdisciplinary forum. Then, it could be useful not only to improve
conceptual meteorological models, but also for application in downscaling
models. The main precipitation structure was a Mesoscale Convective System
(MCS) that crossed the region and that developed as a consequence of the
merging of two previous squall lines. The paper analyses the main
meteorological features that led to the development and triggering of the
heavy rainfalls, with special emphasis on the features of this MCS, its life
cycle and its dynamic features. To this end, 2-D and 3-D algorithms were
applied to the imagery recorded over the complete life cycle of the
structures, which lasted approximately 18 h. Mesoscale and synoptic
information were also considered. Results show that it was an NS-MCS,
quasi-stationary during its stage of maturity as a consequence of the
formation of a convective train, the different displacement directions of
the 2-D structures and the 3-D structures, including the propagation of new
cells, and the slow movement of the convergence line associated with the
Mediterranean mesoscale low. |
