Climate scenario analysis using WRF model and CCSM3 models over London (UK), Athens (Greece), Gliwice (Poland), Helsinki (Finland) and Florence (Italy) for three IPCC scenarios8th International Conference on Air Quality - Science and Application (2012)
AbstractThe combined use of state-of-the-art mesoscale meteorological models such as WRF (Weather Research & Forecasting Model) (NCEP, US) and climate models such as CCSM3 (UCAR, US) leads to important conclusions on the impact of different energy consumption scenarios in th urban metabolism. This contribution is part of the results produced into the BRIDGE EU project (SustainaBle uRban plannIng Decision support accountinG for urban mEtabolism) started in 2008 and ended in 2011. Different energy scenarios were considered in the project and three of them were associated to A2, A1F1 and B1 IPCC scenarios. These three scenarios represent the so-called: BRIDGE in wonderland, Climate change is a burning issue and lack of energy in freezing the economy. These concepts are closely related to the amount of energy used by the mankind according to these scenarios. We have used the initial and boundary conditions, produced and stored in UCAR web site, to drive the WRF simulations over London (UK), Athens (Greece), Gliwice (Poland), Helsinki (Finland) and Florence (Italy). The simulations have been performed with 200 m spatial resolution. We have not respected the rate 1:3 in the classical WRF configuration since the computer time would have been prohibited. We have used the T85 Gaussian grid and 26 vertical levels 6 hour files from CCSM3 to convert it to fixed grid with 1.5º and the 26 vertical hybrid levels to 17 pressure levels, using the regridding and the vertical interpolation technique. We have run July, August and September, 2008 as Commitment scenario and those months for 2030. The results show a high sensitivity of the different energy consumption scenarios used as IC’s and BC’s for WRF model. Sensible and Latent heat fluxes are compared between cities and scenarios and meteorological variables as temperature.
