Abstract Current climate models struggle to capture the mean state and variability of dust emissions. This is partially due to their inability to resolve convection, a consequence of their relatively coarse spatial resolution. Via analysis of output from an offline dust emission scheme forced with output from a global storm‐resolving model, we show ...
