Previous RDPs
The objective of the proposed RDP is to focus on the Olympic Games of Paris in 2024 in order to advance research on the theme of the “future Meteorological Forecasting systems at 100m (or finer) resolution for urban areas”, especially on themes relative to extreme events in summer linked to urbanization: thunderstorms and strong Urban Heat Islands, and their consequences.
Previous summer Olympics FDP took place for Sydney 2000 and Beijing 2008. The scientific objectives of these FDPs focused both on the nowcasting and predictability of thunderstorms at regional scale, using radar, satellite, surface station observations, feature detection and nowcast systems, NWP models with 3-5 km horiztonal resolutions and, for the Beijing FDP, NWP models blended systems. at 3-5km resolution. Automated nowcast systems run during the Sydney and Beijing FDPs had resolutions of 1-3 km horizontal resolutions. These state-of-the-art models were not run at resolutions able to resolve urban meteorological effect. In the more recent Olympics RDPs and FDPs that focused on winter games (Vancouver 2010, Joe et al 2014; Sochi 2014, Kiktev et al 2017; Pyeong-Chang 2018), kilometric models were used, but to study winter weather hazards over mountains.
The Paris 2024 Olympics RDP could take advantage of the results of the recent Tokyo Metropolitan Area Convection Study for Extreme Weather Resilient Cities (TOMACS) RDP, where extreme convective events over Tokyo metropolitan area were studied mostly with radars and other instruments, but also with a few urbanized models at 1km (Pereira Filho et al 2018) and even at 250m of resolution (Bélair et al, 2018).
