Regional Reanalysis Development and Urban Climate

UHI exam­ple from mod­el sim­u­la­tions at 500m res­o­lu­tion dur­ing the first June 2019 heat­wave over the Rhine-Ruhr Area in Ger­many

Future region­al reanaly­sis will move towards fin­er grid spac­ing with a bet­ter rep­re­sen­ta­tion of land sur­face het­ero­gene­ity thus espe­cial­ly enhanc­ing the rep­re­sen­ta­tion of the bound­ary lay­er state. An appli­ca­tion of a ultra-high res­o­lu­tion reanaly­sis is the inves­ti­ga­tion of urban cli­mate and its vari­abil­i­ty espe­cial­ly with regard to urban heat islands (UHIs). Anoth­er pos­si­ble appli­ca­tion is renew­able ener­gy by allow­ing for bet­ter ret­ro­spec­tive esti­mates for the poten­tial of wind and solar pow­er due to an enhanced rep­re­sen­ta­tion of bound­ary lay­er winds and cloud cov­er.
