Exploring Satellite-Derived Relationships between Cloud Droplet Number Concentration and Liquid Water Path Using a Large-Domain Large-Eddy Simulation

Important aspects of the adjustments to aerosol-cloud interactions can be examined using relationship between cloud droplet number concentration (Nd) and liquid water path (LWP). Specifically, this relation constrain role aerosols in leading thicker or thinner clouds response adjustment mechanisms. This study investigates satellite retrieved Nd LWP for a selected case mid-latitude continental high-resolution Large-eddy simulations (LES) over large domain weather prediction mode. Since retrieval uses adiabatic assumption derive Nd, we have also considered (NAd) from LES model comparison. The joint histogram analysis shows that NAd-LWP is approximate agreement. In both cases, peak conditional probability (CP) confined lower NAd LWP; corresponding mean (LWP) weak with NAd. CP larger spread at higher (>50 cm–3), increases non-monotonically increasing cases. Nevertheless, lack negative NAd, entrainment effect on droplets. contrast, simulated Nd-LWP clearly illustrates much more nonlinear (an increase decrease Nd) relationship, which depicts lifetime effect. Additionally, our demonstrates regime dependency (marine continental) retrievals. Comparing local vs large-scale statistics data exhibit only relationship. Hence regime-based even relevant when it comes warm their comparison
