Abstract:: EUREC4A-UK is a programme of observational and modelling research which aims to study the detailed aerosol and cloud processes in the life cycle of shallow trade cumulus clouds and the two-way interactions between the cloud processes and the large-scale dynamics. The different responses of these clouds to warming in global climate models (GCM) explain most of the inter-model differences, yet the physics of these responses remains poorly constrained. The programme is focussed on the participation of UK scientists and the BAS Twin Otter aircraft in EUREC4A (Elucidating the Role of Clouds-Circulation Coupling in Climate). EUREC4A is a coordinated international campaign that aims to address the current lack of understanding of the processes controlling the response of trade-wind cumulus clouds to changing environmental conditions in a warmer climate. The goal of EUREC4A is to examine the interplay between the clouds, atmospheric circulations and climate sensitivity. EUREC4A-UK will make a unique and self- contained contribution to the international programme by: (i) providing observational facilities which are needed as part of the coordinated field campaign; (ii) conducting and leading the analysis of the aerosols, cloud microphysics and boundary-layer processes in the life cycle of shallow trade cumulus clouds; (iii) placing the analysis in the context of the EUREC4A problems by modelling the two-way interactions between the cloud processes and the large-scale dynamics; and (iv) applying the results by testing the new convection scheme in the UM and using the improved model to determine the dominant processes controlling the cloud fields. International partners will complement the re- search with a focus on observing and modelling the macrophysical properties and the environment of trade-cumulus clouds in order to determine: (i) what controls the convective mass flux, mesoscale organization and depth of shallow-cumulus clouds; (ii) how the trade-cumulus cloud fraction varies with turbulence, convective mixing and large-scale circulations; and (iii) the impact this variation has on atmospheric radiation.
