  text: "In this study the response of tropical precipitation extremes to warming
    in organized convection is examined using a cloud-resolving model. Vertical shear
    is imposed to organize the convection into squall lines. Earlier studies show
    that in disorganized convection, the fractional increase of precipitation extremes
    is similar to that of surface water vapor, which is substantially smaller than
    the increase in column water vapor. It has been suggested that organized convection
    could lead to stronger amplifications.\r\nRegardless of the strength of the shear,
    amplifications of precipitation extremes in the cloud-resolving simulations are
    comparable to those of surface water vapor and are substantially less than increases
    in column water vapor. The results without shear and with critical shear, for
    which the squall lines are perpendicular to the shear, are surprisingly similar
    with a fractional rate of increase of precipitation extremes slightly smaller
    than that of surface water vapor. Interestingly, the dependence on shear is nonmonotonic,
    and stronger supercritical shear yields larger rates, close to or slightly larger
    than surface humidity.\r\nA scaling is used to evaluate the thermodynamic and
    dynamic contributions to precipitation extreme changes. To first order, they are
    dominated by the thermodynamic component, which has the same magnitude for all
    shears, close to the change in surface water vapor. The dynamic contribution plays
    a secondary role and tends to weaken extremes without shear and with critical
    shear, while it strengthens extremes with supercritical shear. These different
    dynamic contributions for different shears are due to different responses of convective
    mass fluxes in individual updrafts to warming."
