An example of tropical cyclone recurvature was Typhoon Ioke in 2006. Errors by tropical cyclone prediction models were attributed mainly to Hernan's recurvature. Fern also began its recurvature that day, beginning its turn north. A mid-level trough moving into the Yellow Sea continued Ellis' recurvature. Recurvature back to the north-northeast towards Japan ensued while the typhoon slowly weakened. After recurvature, Kinna accelerated north-northeastward toward Kyushu as it maintained its intensity.
