Fig. 1: Lagrangian Hovmöller space analysis of sugar Trade Cumulus (TrCu) clouds.
From: Not as random: the stable dynamics controlling shallow convective clouds

a GOES--16 satellite image taken over the Caribbean Sea on February 6, 2018. The yellow, red, and green polygons mark fields of non-precipitating small convective TrCu clouds. The dashed lines in each polygon indicate the location of the vertical trace extracted from each Lagrangian corrected image to form the LHS shown in (b, c, d). Each clear white segment in the panels represents a cloud. The thickness of the segment is proportional to the sampled cloud size (along the selected trace), while the segment length represents the cloud lifetime. Note the continuity of the lines, where many new segments appear along the same trajectory as previous clouds.
