| Zusammenfassung |
| This paper constitutes a step towards the understanding of some
characteristics associated with high rainfall amounts and flooding on
Madeira Island. The high precipitation events that occurred during the
winter of 2009/2010 have been considered with three main goals: to analyze the
main atmospheric characteristics associated with the events; to expand the
understanding of the interaction between the island and the atmospheric
circulations, mainly the effects of the island on the generation or
intensification of orographic precipitation; and to evaluate the performance of
high resolution numerical modeling in simulating and forecasting heavy
precipitation events over the island. The MESO-NH model with a horizontal
resolution of 1 km is used, as well as rain gauge data, synoptic charts and
measurements of precipitable water obtained from the Atmospheric InfraRed
Sounder (AIRS). The results confirm the influence of the orographic effects
on precipitation over Madeira as well as the tropical–extratropical
interaction, since atmospheric rivers were detected in six out of the seven
cases analyzed, acting as a low level moisture supplier, which together with
the orographic lifting induced the high rainfall amounts. Only in one of the
cases the presence of a low pressure system was identified over the
archipelago. |
