According to standard international meteorological practice, visual observations must be made once every three hours, but because the Yushan Weather Station is grouped among the smallest "grade-four" stations, it only has to make eight manual readings from 5 a.m. to 9 p.m. For the rest of the time, observations are made and recorded automatically by the various meteorological apparatus.
根據國際氣象觀測的通例，人工觀測每三小時進行一次，但玉山站屬於編制最小的「四等氣象站」，只在早上五點到晚上九點間進行八次人工觀測，其餘時間則由儀器自動觀測。
