Scientificresults: Thestatementthatatmosphericmodelsareonlyanapproximationofreality,and<br />
thattheirdynamicsarethereforedifferentfromnature,isnotnew.However,thetalksofthisconference<br />
gaveadetailedandquantitativeimpressionofmodelerrorsandforecastaccuracy. Intermsofatmosphericmodelling,theaudiencewasratherbroad:Differenttimescales(weatherandclimate),different<br />
physical(sub-)systems(clouds,theatmosphere,andfullclimatemodels),differentintentions(precise<br />
weatherforecasts,longrunclimateprojections),differentmethodologies(statisticalpredictionanddownscalingschemes,ensembleoptimization,dataassimilationtechniques).<br />
