CORDEX Programme
Changes in frequency of strong wind episodes (> 13.4 m/s; in %) over the Black Sea based on the ensemble mean of 4 regional climate models from EURO-CORDEX in 2071-2100 vs. 1971-2000. Spatial resolution is 12.5 km.
EURO-CORDEX domain
Benefits and limitations of climate model results Numerical experiments are the equivalents of lab experiments in physics.
In the present modeling effort we start to look into more spatial and temporal scales of climate – some of them on which regional process and extremes take place.
Climate model results allow to make sound and informed decision by coupling climate information with impact and socio economic knowledge.
On the other hand
there are limitations in using model results due to problems in observation system which feed in models, model representations of reality etc.
But
we can get rid of a number of these limitations by advancing our knowledge.
However
there will be always a level of uncertainty due to intrinsic chaotic nature of some processes taking place in the climate system;
we have to cope with a level of uncertainty in the mitigation and adaptation efforts.
Thank you!
