| Zusammenfassung |
Tropical-like cyclones rarely affect the Mediterranean region but they can
produce strong winds and heavy precipitations. These warm-core cyclones,
called MEDICANES (MEDIterranean hurriCANES), are small in size, develop over
the sea and are infrequent. For these reasons, the detection and forecast of
medicanes are a difficult task and many efforts have been devoted to identify
them.
The goals of this work are to contribute to a proper description of these
structures and to develop some criteria to identify medicanes from numerical
weather prediction (NWP) model outputs. To do that, existing methodologies
for detecting, characterizating and tracking cyclones have been adapted to
small-scale intense cyclonic perturbations. First, a mesocyclone detection
and tracking algorithm has been modified to select intense cyclones. Next,
the parameters that define the Hart's cyclone phase diagram are tuned and
calculated to examine their thermal structure.
Four well-known medicane events have been described from numerical simulation
outputs of the European Centre for
Medium-Range Weather Forecast (ECMWF) model. The predicted cyclones and their evolution have
been validated against available observational data and numerical analyses
from the literature. |
