Some of the extreme weather events are ecological and economically disruptive, which affects the lives of thousands of people. A “Climate Watch” can provide information about evolving or foreseen significant weather extremes that may have substantial impacts on a regional scale. As part of a Climate Watch System, extreme weather events for the WMO region RA VI were monitored, stored weekly in a Geodatabase (Knowledge Database on EuROpeaN Climate ExtRemes / KRONER) and published in the monthly bulletins.
