A joint WWRP and GURME action
This RDP proposal aims to provide answers to scientific questions related to urban areas meteorology, that are particularly relevant for WWRP as well as for GURME. Among the 17 and 8 strategic axes from WWRP and GURME, respectively, this RDP will more specifically address these:
AA 11: UNDERSTAND NEEDS:
Improve understanding and knowledge of the relationship between the urban physical and built environment, the social, behavioural and economic needs of its population, and the requirements for integrated weather-related environmental services
AA 12: OBSERVATIONS & PROCESSES:
Improve observations and understanding of the unique urban physical processes, including dynamical, chemical and hydrologic
AA 13: URBAN PREDICTION:
Develop, validate and demonstrate urban prediction capabilities, toward building urban environment integrated information systems to support decision making for different applications in different parts of the world
WWRP High Impact Weather
AA 5: VERIFICATION:
Develop methods to verify forecasts and warnings of high-impact weather and its impacts and demonstrate their benefit, with a focus on probabilistic and impact-based methods, including collecting and processing suitable observations (particularly non-conventional weather observations by non-conventional means); assess the impact of near misses and false alarms; and evaluate the end-to-end forecast chain with emphasis on what is of value to the user
WWRP Evolving technologies
AA 17: NEW OBSERVATIONS
Prepare for exploitation of information from new, advanced observing systems, as well as commodity-technology-based data
GURME strategic axes
GURME-2. Develop activities on research questions/issues that transcend disciplines and require leveraging a broader community to develop improved forecasting concepts and tools to resolve complex urban environments at increasing scales; facilitate data sharing and establishment of test beds; The test-beds will be the Paris (inland) and Marseilles (coastal) agglomerations.
GURME-3. Given the integrative nature of modeling, the on-going scientific trend towards seamless predictions and the evolution of technology, actively engage other WMO advisory and working groups within WWRP, GAW and the rest of its organization, to address this complex and multidisciplinary challenge;
GURME-4. While megacities will continue to receive particular attention, orient its research to cover the full array of urban environments that are key to the broader scientific question of urban-scale modelling; In addition to Paris, the coastal Mediterranean city of Marseilles will be studied.
GURME-7. Build capacity through its research projects, identifying those environments that constitute gaps in the overall directions of the GURME program and encourage in its projects the development and testing of derived services. The products themselves would take the form of forecasts, alerts and warnings and/or real-time/NRT maps or databases; The ultimate objective is to provide pertinent forecasts and warnings at urban and infra-urban scale.
