  1. Sea-level pressure has a unit of “hPa”. “W”, “M”, and “Y” mean Wakkanai, Minami-Torishima, and Yonagunijima. “Y–M”, “Y–W”, and “W—M” are defined as the difference of sea-level pressure between Yonagunijima and Minami-Torishima, between Yonagunijima and Wakkanai, and between Wakkanai and Minami-Torishima
