remains cloudier. The two cases differ in initial MBL depth, decoupling, microphysics, and large-scale forcings. Note that the agreement between outbound flight number and case number (L06 coming from RF06, L10 from RF10) is coincidental. b. Satellite and reanalysis data In addition to the GV measurements, satellite and reanalysis data are used. Where possible, these are compared to aircraft observations for additional validation. The satellite data consists of cloud property fields generated from

forcing, since entrainment cooling is less with deep-ocean mixed layers, and sustain air–sea fluxes into the storm ( Shay et al. 2000 ; Lin et al. 2005 , 2009 , 2013 ; Shay and Uhlhorn 2008 ; Jaimes and Shay 2009 , 2010 ; Jaimes et al . 2015 ). In addition to ocean thermal structure, a few studies have indicated that the upper-ocean salinity stratification within the Amazon–Orinoco River plume plays a role in modulating SST during TC passage by reducing the efficiency of upper-ocean mixing

are conveyed by the RMW and an asymmetry factor. The size term here is not necessarily representative of the full vortex size, but a larger RMW tends to correspond to a larger vortex. The extent of the vortex is often defined by the radius of minimal tropical storm force winds (i.e., >17 m s −1 ; Chavas and Emanuel 2010 ), but this definition of size is less relevant to the present study. To determine the RMW from the two-dimensional surface winds, azimuthally averaged wind speeds are produced

-scale evolution during that period. Because of the relatively short run time and the size of the domains, nudging was not used. This further allows us to assess the output from WRF, independent of the forcing data. Subsequent use of analysis nudging for the same setup in other tests has revealed a negligible difference between the runs with and without nudging. During this particular event, the air temperature rose from a daily average of −24.5°C at KPC_U and −19.4°C at KPC_L on 28 November, to a daily

bins, was positively correlated with estimated inversion strength (EIS) with a regression slope close to past climatology. After controlling for EIS, the low cloud cover was not well correlated with cloud droplet concentration, which suggests that the Sc–Cu transition is not strongly controlled by aerosol processes. This contrasts with some recent idealized large-eddy simulation studies (e.g., Yamaguchi et al. 2017 ), but is consistent with another such study using data-constrained forcings and
