Air-sea and air-sea-ice fluxes in the Southern Ocean play a critical role global climate through their impact on overturning circulation oceanic heat carbon uptake. The challenging conditions have led to sparse spatial temporal coverage of observations. This has 'knowledge gap' that increases uncertainty atmosphere ocean dynamics boundary-layer thermodynamic processes, impeding improvements weather models. Improvements will require both process-based research understand mechanisms governing...
The tropical Atlantic is home to multiple coupled climate variations covering a wide range of timescales and impacting societally relevant phenomena such as continental rainfall, hurricane activity, oceanic biological productivity, atmospheric circulation in the equatorial Pacific. also connects southern northern branches meridional overturning receives freshwater input from some world's largest rivers. To address these diverse, unique, interconnected research challenges, rich network ocean...
Abstract Sea surface temperature (SST) anomalies caused by a warm core eddy (WCE) in the Southwestern Atlantic Ocean (SWA) rendered crucial influence on modifying marine atmospheric boundary layer (MABL). During first cruise to support Antarctic Modeling and Observation System (ATMOS) project, WCE that was shed from Brazil Current sampled. Apart traditional meteorological measurements, we used Eddy Covariance method directly measure ocean–atmosphere sensible heat, latent momentum, carbon...
Abstract Sea ice is an important and complex component of the Earth system considered a sensitive indicator climate change. The seasonal sea cycle regulates exchange heat salinity, altering energy balance between high low latitudes as well ocean atmospheric circulation. accurate representation Antarctic has been hot topic in modelling community lacks conclusive answers. In this paper, we evaluated ability 11 models from Coupled Model Intercomparison Project Phase 5 ( CMIP5) 6 CMIP6) to...
The oceanic South Atlantic Convergence Zone (SACZ) has played a major role during America's 2021/2022 summer extreme rainy season, being responsible for more than 90% of the precipitation in some regions Southeast Brazil and Southwestern Ocean (SWA). was unique rare considered an abnormally humid season as verified by official Brazilian Institutes. First, unusual number cases SACZ episodes (seven), highest recorded last decade. Second, all that occurred were assumed characteristics...

The Southern Ocean (SO) is crucial for global climate regulation by absorbing excess heat and anthropogenic CO2. However, representing air-sea fluxes in models remains a challenge, particularly regions characterised strong ocean–atmosphere–sea ice interactions. This study analysed air–sea over the SO using four products seven CMIP6 HighResMIP pairs, comparing mean state trends (1985–2014) of sensible latent (SHF LHF, respectively) impact grid resolution refinement on their estimation. Our...
This paper presents a description of marine atmospheric boundary layer (MABL) and oceanic (OBL) interactions at the Brazil‐Malvinas Confluence. Although this region is known as one most energetic zones World Ocean, very few studies have addressed mechanisms OA interaction there. Based upon novel, direct in situ simultaneous observations, our results show that OBL‐MABL exchanges are closely correlated with sea surface temperature (SST) field. The heat fluxes range from 110 W.m −2 over warm...
This study analyzes and discusses data taken from oceanic atmospheric measurements performed simultaneously at the Brazil‐Malvinas Confluence (BMC) region in southwestern Atlantic Ocean. area is one of most dynamical frontal regions world ocean. Data were collected during four research cruises once a year consecutive years between 2004 2007. Very few studies have addressed importance studying air‐sea coupling BMC region. Lateral temperature gradients as high 0.3°C km −1 surface subsurface....
