EUREC4A-OA
Improving the representation of small-scale nonlinear ocean-atmosphere interactions in Climate Models by innovative joint observing and modelling approaches
EUREC4A-OA implements ad-hoc innovative observations and a hierarchy of numerical simulations focusing on mesoscale and submesoscale ocean dynamics and the atmospheric boundary layer at scales ranging from 20 m to 1000 km over the northwest tropical North Atlantic. The aim is to advance our knowledge of the phenomenology and representation of air-sea interactions, physical and biogeochemical ocean small-scale non-linear processes in ESMs but also in NWPs, S2Ss and decadal forecasts operational systems.
-
Assessing the impact of the diurnal cycle on energy, water and CO2 ocean-atmosphere exchangesand quantifying the modification of diurnal cycle and the related exchanges by meso-scale and submeso-scale features and other extreme conditions
-
Assessing the impact of the diurnal cycle on energy,water and CO2 ocean-atmosphere exchanges
-
The identification and quantification of the processes ruling the ocean-atmosphere exchanges and uptake of heat,momentum and CO2 at the ocean nonlinear small scales (from a few tens of meters to 500 km)
-
The role of various processes (diurnal cycle, ocean nonlinear small scales, boundary layer aerosols)on the atmosphere shallow convection and cloud formation
-
To provide improved models metrics and parameterizationsfor the above processes to be integrated in operational prediction systems and ESMs.

About
EUREC4A-OA brings together international specialists of ocean, atmosphere physical and biogeochemical observations and numerical modelling as well as scientists working on numerical parameterization, operational systems and future projections to address four objectives.

JPI Climate & JPI Oceans Joint Transnational Call on the Next Generation Climate Science in Europe for Oceans
Oceans play a key role in the climate system and are also affected by climate change. As confirmed by the IPCC special report on ocean and cryosphere, ocean dynamics are a major modulator of weather and climate including future trends and extremes. However, there are still uncertainties in the understanding and quantification of key climate-ocean interactions and the ocean’s buffering capacities for absorbing heat and CO2. This joint call aims to address these uncertainties.
