Higher CAPE implies what about updrafts?

More buoyant energy means stronger updrafts. CAPE measures the energy available to lift a parcel as it rises through the environment; when CAPE is high, the rising air is more buoyant and accelerates faster, leading to stronger updrafts in thunderstorms. In a simple view, the maximum updraft speed scales roughly with the square root of CAPE, so larger CAPE values yield noticeably stronger upward motion. Of course, whether those strong updrafts actually develop depends on triggering and suppressing factors like CIN and entrainment, but the basic link is that greater CAPE provides more energy for updrafts.
