Special CASPO Seminar: Dr. Jan Keller, "The added value of regional reanalysis"

12/05/2019 - 3:00pm to 4:00pm
101 Nierenberg Hall
Event Description: 

Dr. Jan Keller

Hans-Ertel-Centre for Weather Research

AbstractIn the framework of the Hans-Ertel-Centre for Weather Research (HErZ - a virtual center of university groups dedicated to basic research towards the needs of the German National Meteorological Service DWD) two regional reanalysis data sets for Europe have been produced at 6 km and 2 km horizontal resolution, respectively. Evaluation and comparison of the data sets point to their added value with respect to global reanalyses. Hence, efforts are continuously made in order to enhance the existing and develop new regional reanalysis systems and therefore improve the representation of the atmospheric state estimates in regional reanalyses.

The presentation outlines the main motivation for the development of regional reanalyses and describes the setup of the specific reanalysis systems. Further, evaluations are shown for various parameters in order to illustrate the benefit of regional reanalyses in comparison to the driving global reanalyses with respect to the representation of weather as well as climate. In addition, current work and future developments in the field of regional reanalysis at HErZ and DWD are presented.
