Synoptic-mesoscale analysis and numerical modeling of a tornado event on 12 February 2010 in northern Greece
Description (Dublin Core)
Tornadoes are furious convective weather phenomena, with the maximum
frequency over Greece during the cold period (autumn, winter).This study
analyzes the tornado event that occurred on 12 February 2010 near Vrastama
village, at Chalkidiki's prefecture, a non urban area 45 km southeast of
Thessaloniki in northern Greece. The tornado developed approximately between
17:10 and 17:35 UTC and was characterized as F2 (Fujita Scale). The tornado
event caused several damages to an industrial building and at several
olive-tree farms.

A synoptic survey is presented along with satellite images, radar products
and vertical profile of the atmosphere. Additionally, the nonhydrostatic
WRF-ARW atmospheric numerical model (version 3.2.0) was utilized in analysis
and forecast mode using very high horizontal resolution (1.333 km × 1.333 km) in order to represent the ambient atmospheric conditions. A comparison
of statistical errors between WRF-ARW forecasts and ECMWF analysis is
presented, accompanied with LGTS 12:00 UTC soundings (Thessaloniki Airport)
and forecast soundings in order to verify the WRF-ARW model. Additionally, a
comparison between WRF-ARW and ECMWF thermodynamic indices is also
presented. The WRF-ARW high spatial resolution model appeared to simulate
with significant accuracy a severe convective event with a lead period of 18 h.
