This is the temperature of air particles that do not contain water vapor when they are adiabatically brought to standard atmospheric pressure (1000 hectopascals). If the initial temperature (absolute temperature) is T and the atmospheric pressure is p, the potential temperature θ is defined by the following equation. θ=T(1000/p) 0.29 [Hiroshi Matano] "Introduction to Synoptic Meteorology" by Yoshimitsu Ogura (2000, University of Tokyo Press) [Reference] | | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
水蒸気を含んでいない空気粒子を断熱的に標準気圧(1000ヘクトパスカル)までもってきたとき、その空気粒子が示す温度をいう。初めの温度(絶対温度)をT、気圧をpとすれば、温位θは次の式で定義される。 θ=T(1000/p)0.29 [股野宏志] 『小倉義光著『総観気象学入門』(2000・東京大学出版会)』 [参照項目] | | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
