Short summary
Downdraft processes in climate models are poorly constrained, largely due to a lack of robust, statistical relationships describing them. Using multi-instrument data from the GoAmazon2014/5 campaign, downdraft properties of mesoscale-organized and unorganized systems are compared and such statistics are presented. Both vertical velocity retrievals and thermodynamic arguments are consistent in suggesting a spectrum of downdraft mass origin levels throughout the lowest few kilometers.
Downdraft processes in climate models are poorly constrained, largely due to a lack of robust,...
