Climate Impact Company Research: Accumalative Cyclone Energy (ACE) Index Clearly Identifies The Destructive Power of the 2017 Season

    Show all

    The ACE Index, as developed and applied by NOAA is an ideal metric to quantify the potential of an active hurricane season because it best captures the dynamics supportive of stronger, more vigorous tropical systems that result in higher ACE values.  When analyzed by high ACE years and low ACE years, clearly defined atmospheric teleconnection patterns that are predictable months in advance are seen, increasing forecast confidence and lead time.  It is recommended that ACE be used as a predictor for Atlantic hurricane season potential instead of just providing an estimate of total named storms, hurricanes, and major hurricanes.
