The structure of convective rain cells at mid-latitudes
The structure of convective rain cells mid-latitudes
2010/1/27
Rain cells are structures which represent an important component of convective precipitation and a study of their properties represents a necessary step both towards improved stochastic models of smal...
Exploitation of cloud top characterization from three-channel IR measurements in a physical PMW rain retrieval algorithm
three-channel IR measurements physical PMW
2010/1/27
Rainfall intensity estimates by passive microwave (PMW) measurements from space perform generally better over the sea surface with respect to land, due to the problems in separating true rain signatur...

This study investigates the atmospheric pattern circulations associated with heavy rainfall (HR) days in Calabria, southern Italy, and contributes to the understanding of the dynamical mechanisms that...
Characterization of a Mediterranean flash flood event using rain gauges,radar,GIS and lightning data
Characterization Mediterranean flash flood event rain gauges radar GIS lightning data
2010/1/28
Flash flood events are very common in Catalonia, generating a high impact on society, including losses in life almost every year. They are produced by the overflowing of ephemeral rivers in narrow and...

2010/1/28
Polarimetric radar variables of rainfall events, like differential reflectivity ZDR, or specific differential phase KDP, are better suited for estimating rain rate R than just the reflectivity factor ...
Synoptic climatological analysis of Red Sea Trough and non-Red Sea Trough rain situations over Israel
Synoptic climatological analysis Red Sea rain situations Israel
2010/1/27
Winter (October to April) rainfall in Israel is caused mostly by migrating Mediterranean cyclones but certain rain situations are accompanied by a low pressure trough extending northward from the sout...
Heavy rain prediction using deterministic and probabilistic models – the flash flood cases of 11–13 October 2005 in Catalonia (NE Spain)
deterministic and probabilistic models the flash flood cases Catalonia (NE Spain)
2010/1/27
Between the 11 and 13 October 2005 several flash floods were produced along the coast of Catalonia (NE Spain) due to a significant heavy rainfall event. Maximum rainfall achieved values up to 250 mm i...
