Short summary
This study presents airborne measurements in shallow convection over land to investigate the dynamic properties of clouds focusing on possible narrow downdraughts in the surrounding of the clouds. A characteristic narrow downdraught region (subsiding shell) is found directly outside the cloud borders for the mean vertical wind distribution. The subsiding shell results from the distribution of the highly variable updraughts and downdraughts in the near vicinity of the cloud.
