成分の質量を補正します. xyzf_QMixRef が与えられた場合には, 全球積分値が xyzf_QMixRef のそれと同じになるように補正します. xyzf_QMixRef が与えられない場合には, 全球積分値が補正前のそれと同じになるように補正します. xyzf_DQMixDt には xyz_QMix の変化量が返ります.

This routine fixes masses of constituents. If xyzf_QMixRef is given, the mass is fixed to match its global integrated value is the same as that of xyzf_QMixRef. If xyzf_QMixRef is not given, the mass is fixed to match its global integrated value is the same as that of pre-fixed value. Variation of xyzf_QMix is returned to xyz_DQMixDt.

鉛直層内で成分の質量を補正します. xyzf_QMixRef が与えられた場合には, 全球積分値が xyzf_QMixRef のそれと同じになるように補正します. xyzf_QMixRef が与えられない場合には, 全球積分値が補正前のそれと同じになるように補正します. xyzf_DQMixDt には xyz_QMix の変化量が返ります.

This routine fixes masses of constituents in each vertical layer. If xyzf_QMixRef is given, the mass is fixed to match its global integrated value is the same as that of xyzf_QMixRef. If xyzf_QMixRef is not given, the mass is fixed to match its global integrated value is the same as that of pre-fixed value. Variation of xyzf_QMix is returned to xyz_DQMixDt.

Williamson and Olson (1994) の方法に従い, 成分の質量を補正します. xyzf_QMixRef が与えられた場合には, 全球積分値が xyzf_QMixRef のそれと同じになるように補正します. xyzf_QMixRef が与えられない場合には, 全球積分値が補正前のそれと同じになるように補正します. xyzf_DQMixDt には xyz_QMix の変化量が返ります.

This routine fix masses of constituents following a method proposed by Williamson and Olson (1994). If xyzf_QMixRef is given, the mass is fixed to match its global integrated value is the same as that of xyzf_QMixRef. If xyzf_QMixRef is not given, the mass is fixed to match its global integrated value is the same as that of pre-fixed value. Variation of xyzf_QMix is returned to xyz_DQMixDt.
