Tetens (1930) より, 飽和蒸気圧 $ p^{*} $ に関する以下の式 を用い, 飽和比湿および飽和比湿の温度微分の値を算出します.
Saturation specific humidity and temperature derivative of it are calculated with a folloing formula for saturation watar vapor pressure $ p^{*} $ in Tetens (1930).
\[
q^{*} (T, p) = 611 \varepsilon \frac{ \exp \left( \frac{l}{R_v} \left( \frac{1}{273} - \frac{1}{T} \right) \right) } { p } \] \[ \DP{q^{*} (T, p)}{T} = 611 \varepsilon \frac{l}{R_v T^2} \frac{ \exp \left( \frac{l}{R_v} \left( \frac{1}{273} - \frac{1}{T} \right) \right) } { p } = \frac{q^{*} l}{R_v T^2}
\]
ここで, $ T $ は温度, $ p $ は気圧, $ R_v $ は凝結成分の気体定数, $ varepsilon $ は凝結成分と大気の分子量比, $ l $ は凝結成分の潜熱です.
