Cloud suck is a phenomenon commonly known in paragliding and hang gliding where pilots experience significant lift due to a thermal under the base of cumulus clouds, especially towering cumulus and cumulonimbus. The vertical extent of a cumulus cloud is a strong indicator of the level of lift beneath it, and the potential for cloud suck. Cloud suck commonly occurs in low pressure weather and in humid conditions.
