Naud, C.M., G.S. Elsaesser, and J.F. Booth, 2023: Dominant cloud controlling factors for low-level cloud fraction: Subtropical versus extratropical oceans. Geophys. Res. Lett., 50, no. 19, e2023GL104496, doi:10.1029/2023GL104496.

To improve cloud feedback understanding and simulation, observations have been used to quantify the rate of change of cloud radiative properties as a function of specific environmental metrics (or cloud controlling factors; CCFs). The study focuses on low-level cloud dominated regions during 2006-2010. For each ocean gridpoint, Spearman's rank correlation coefficients of daily mean observed cloud fraction versus (i) 10-m wind, (ii) sensible heat flux (SHF), (iii) sea surface temperature, (iv) estimated inversion strength (EIS), (v) 850hPa vertical velocity, and (vi) the M parameter (ΔΘskin888hPa) are sorted to identify the dominant CCFs in both extratropics (30°-60°N/S) and subtropics (30°S to 30°N). A novel map for visualizing dominant CCFs for low-level cloud fraction reveals that: ΔΘskin888hPa dominates in the subtropical stratocumulus regions while 10-m winds dominate in shallow cumulus regions but in the extratropics, a different inversion structure diagnostic (EIS) dominates, while SHF dominates in western boundary current areas.
