The lowest instantaneous mean sea - level pressure of 1000 . 9 hpa was recorded at the hong kong observatory at about 4 p . m . on 18 august 天文臺于八月十八日下午4時左右錄得最低瞬時海平面氣壓1000 . 9百帕斯卡。
The lowest instantaneous mean sea - level pressure of 990 . 1 hpa was recorded at the hong kong observatory at 4 . 50 p . m . and 5 . 37 p . m . on 4 august 天文臺于八月四日下午4時50分及5時37分錄得最低瞬時海平面氣壓990 . 1百帕斯卡。
The output voltage of the transducer is adjusted electronically to give the mean sea - level pressure which is continuously displayed digitally 傳感器的輸出電壓由電子裝置調(diào)整,得出平均海面氣壓的數(shù)值,測量結(jié)果不斷地以數(shù)字形式顯示出來。
The correlations between the tide level of coast tidal gauge stations and the tide level of offshore sand ridges , and between mean high water level and mean water level as well as mean sea - level were discussed when studying the tidal gauge records 在潮位資料的分析過程中還探討了沿岸驗潮站與岸外沙洲潮位的相關(guān)性以及平均潮位、平均高潮位和平均海平面之間的相關(guān)關(guān)系。
