“By creating a better, more consistent historical data set, we’ve been able to weed out quality issues that introduce a lot of uncertainty,” Kossin said. “Then, by looking only at the strongest tropical cyclones, where the relationship between storms and climate is most pronounced, we are able to observe the increasing trends in storm intensity that both the theory and models say should be there.”
While Elsner said the heat-engine theory might explain how tropical cyclones intensify given that everything else is the same.
he noted, “We still do not have a complete understanding of why some cyclones intensify, sometimes quite rapidly, and others don’t."
