力学過程を演算するモジュールです. 水平離散化にスペクトル法を, 鉛直離散化には Arakawa and Suarez (1983) を用いています.
時間積分法にはリープフロッグスキームを用いています. デフォルトでは, $ Delta t $ を大きくとるために, 重力波項に セミインプリシット法を適用しています. NAMELIST#dynamics_hspl_vas83_nml の TimeIntegScheme を変更することで, 重力波項をエクスプリシット法によって解くことも可能です.
This is a dynamical core module. Spectral method (for horizontal) and Arakawa and Suarez (1983) method (for vertical) are used.
Leap-frog scheme is used as time integration. By default, semi-implicit scheme is applied to gravitational terms for extension of $ Delta t $ . Explicit scheme can be applied to gravitational terms by changing "TimeIntegScheme" in "NAMELIST#dynamics_hspl_vas83_nml".

時間積分を行い, 時刻 $ t $ の物理量の時間変化と $ t-\Delta t$ の物理量から 時刻 $ t+Delta t $ の物理量を計算します.
時間積分法にはリープフロッグスキームを用いています. ただし拡散項には前方差分を用いています. デフォルトでは, $ Delta t $ を大きくとるために, 重力波項に セミインプリシット法を適用しています. NAMELIST#dynamics_hspl_vas83_nml の TimeIntegScheme を変更することで, 重力波項をエクスプリシット法によって解くことも可能です.
With time integration, calculate physical values at $ t+Delta t $ from tendency at $ t $ and physical values at $ t-\Delta t $ .
Leap-frog scheme is used as time integration scheme. And forward difference is used to diffusion terms. By default, semi-implicit scheme is applied to gravitational terms for extension of $ Delta t $ . Explicit scheme can be applied to gravitational terms by changing "TimeIntegScheme" in "NAMELIST#dynamics_hspl_vas83_nml".
