飽和比湿の算出

Evaluate saturation specific humidity

Note that Japanese and English are described in parallel.

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.

飽和比湿の計算にはデフォルトでは Tetens (1930) を用いる (saturate_t1930 参照). また, Config.mk の CPPFLAGS に -DLIB_SATURATE_NHA1992 を指定すると Nakajima et al. (1992) を用いる (saturate_tnha1992 参照).

By default, Tetens (1930) is used for calculation of saturation specific humidity (See "saturate_t1930"). If "-DLIB_SATURATE_NHA1992" is specified to "CPPFLAGS" in Config.mk, Nakajima et al. (1992) is used (See "saturate_nha1992").
