Relative positive (negative) change between consecutive MLD climatological 4-day composites appearing with simultaneous positive (negative) relative change in the CHL climatological 4-day composites in the five Red Sea sub-regions. The relative changes of each variable are calculated with respect to their previous value and expressed as a percentage.
