What is a front?
elongated zone of strong horizontal temperature gradient
elongated: length ~1000km / width ~100-200km
strong: ~5 K/100km
Two kinds of extreme events
* Statistical (extreme in comparison to climatological distribution during previous decades)
* Impact-related (strong impact on society
Extreme precipitation on different scales
* Convective precipitation extremes (small temporal / spacial scales; local and strong coupling between moisture and dynamics)
-> can lead to flash floods
* Large-scale precipitation extremes (large accumulated precipitation over several days; triggered by synoptics)
-> can lead to large-scale floods
IWV
integrated water vapor
Moisture integrated over all height levels(can be observed via satellite)
IVT
integrated vapor transport
horizontal transpot over all height levels ( qv integrated over dp
