Number of landfalls: Number of times where the tropical cyclone eye crosses mainland China as reported by the China Meteorology Agency. Only one landfall per tropical cyclone is counted even if some tropical cyclones can make multiple landfalls.
Intensity at landfall: The China Meteorological Agency reported maximum wind speed (m/s ) at the time of landfall for all storms.
Accumulated Cyclone Energy: The ACE of the year in the basin is calculated by summing the squares of the estimated maximum sustained velocity of every active tropical storm (wind speed 35 knots [65 km/h, 40 mph] or higher), at six-hour intervals as reported by JTWC. Units are n 104 knots2
