Summary

Tyler Tatro, a PhD candidate at the University of Miami, presents his research on smoke-cloud interactions in the Southeast Atlantic. The region hosts one of the world’s largest stratocumulus cloud decks, and seasonal biomass burning in southern Africa produces absorbing aerosol that can either enhance or suppress cloud development depending on its vertical location. The talk is divided into two parts: first, synoptic-scale processes in June-August that control smoke transport into the marine boundary layer, and second, decadal trends in the later burning season (August-October). Using reanalysis (ERA5, CAMS) and satellite observations, Tatro shows that a weak thermal low over Angola is key to advecting smoke into the marine boundary layer, increasing cloud droplet number concentration but reducing cloud fraction. This variability affects estimates of shipping track impacts on cloud brightness. On decadal timescales, circulation changes have strengthened free-tropospheric winds, lofting more aerosol above the cloud deck, contributing to a positive aerosol radiative effect. The talk highlights the importance of vertical aerosol location and the need for accurate representation in climate models.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable insights into the complex interactions between absorbing aerosol and stratocumulus clouds, a critical but understudied area. The argumentation is solid, based on multiple lines of evidence: reanalysis, satellite data, and in-situ observations. The speaker clearly explains the physical mechanisms and supports claims with quantitative analyses, such as correlations and composites. The discussion of implications for marine cloud brightening and shipping tracks adds practical relevance. The presentation is well-structured, with clear transitions between synoptic and decadal scales.

Scientific Rigor, Source Quality, Title Accuracy

The research appears scientifically rigorous, using established datasets (ERA5, CAMS, MODIS, CALIPSO) and comparing with observations. The speaker cites relevant literature (e.g., Ghan and Feingold 2022, Meyer et al.) and acknowledges limitations, such as reanalysis underestimating magnitudes. The title accurately reflects the content. No comments were provided for analysis.

Contribution & Novelties

The talk contributes new insights into the synoptic and decadal drivers of smoke-cloud interactions in the Southeast Atlantic, particularly the role of the Angolan thermal low in modulating marine boundary layer aerosol and cloud properties. It also highlights the implications for marine cloud brightening and shipping track studies. The use of reanalysis and satellite data to bridge scales is a methodological strength.
