caption_attribution_description: Français&#160;: Hodographe typique associé avec le changement linéaire des vents avec l'altitude dans un orage multicellulaire. Les cellules orageuses individuelles dans le groupe se déplacent dans la direction du cisaillement dans la couche alors que la ligne orageuse se déplacent dans la direction et à la vitesse du vent moyen dans la couche. English: Typical hodograph of a multicellular cluster, a group of cells in different stages of development. It shows usually a "straight-line" (unidirectional) wind shear indicating speed and/or directional shear conducive for MCSs. The complex moves with the mean wind while individual cells move along the shear.
context_page_description: A multicellular thunderstorm cluster is a thunderstorm that is composed of multiple cells, each being at a different stage in the life cycle of a thunderstorm. It appears as several anvils clustered together. A cell is an updraft/downdraft couplet. These different cells will dissipate as new cells form and continue the life of the multicellular thunderstorm cluster with each cell taking a turn as the dominant cell in the group.
context_section_description: The formation of multicellular thunderstorms imply that the updraft in the mother thunderstorm is offset from its downdraft. New cells usually form in the upwind (usually western or southwestern) part of the storm where the downdraft of the mature cells meet the environmental wind, lifting the air parcel and triggering new convection. The mature cells are thus usually in the center of the storm, and dissipating cells are usually in the downwind (usually eastern or northeastern) part of the storm.
