Spatiotemporal dynamics of fog and low clouds in the Namib unveiled with ground- and space-based observations

A new conceptual model of the spatiotemporal dynamics of fog and low clouds (FLCs) in the Namib Sand Sea has been unveiled, revealing significant seasonal and diurnal variations. Satellite and ground-based observations show that FLC patterns differ between coastal and inland regions, with coastal areas experiencing earlier onset times due to advective processes. The study also highlights a strong correlation between FLC timing and distance from the coastline, suggesting dominant advective influences. This research advances our understanding of Namib-region fog dynamics by integrating coherent spatial and temporal data, addressing previous gaps in knowledge.
