The Japan Meteorological Agency (JMA) analysed that the 10-minute maximum sustained winds of Typhoon Megi in 2010 was 125 knots (230 km/h, 145 mph), making it the second strongest tropical cyclone in the Northwest Pacific Ocean on record along with Bess in 1982 and Haiyan in 2013, only after Tip in 1979. The Hong Kong Observatory analysed that Megi was the strongest tropical cyclone in the Northwest Pacific Ocean since Tip in 1979 by attaining the 10-minute maximum sustained winds at 270 km/h (145 knots, 165 mph). A hurricane hunter aircraft indicated 1-minute maximum sustained surface winds of before peak intensity, which was equivalent to Tip in 1979.
