力学過程 (スペクトル法, Arakawa and Suarez (1983))

Dynamical Core (Spectral method, Arakawa and Suarez (1983))

Note that Japanese and English are described in parallel.

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 (Bourke, 1988) 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 (Bourke, 1988) (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 in order to enlarge the value of $ Delta t $ . Explicit scheme can be applied to gravitational terms by changing "TimeIntegScheme" in "NAMELIST#dynamics_hspl_vas83_nml".

力学過程の演算を行い, 与えられた $ t-\Delta t $ および $ t $ の 東西風速 (xyz_UB, xyz_UN), 南北風速 (xyz_VB, xyz_VN), 温度 (xyz_TempB, xyz_TempN), 質量混合比 (xyzf_QMixB, xyzf_QMixN), 地表面気圧 (xyz_PsB, xyz_PsN), および地表面高度 (xy_SurfHeight) から, $ t+Delta t $ の 東西風速 (xyz_UA), 南北風速 (xyz_VA), 温度 (xyz_TempA), 質量混合比 (xyzf_QMixA), 地表面気圧 (xyz_PsA) を返します.

別の物理プロセスによる渦度, 発散, 温度, 比湿の変化を, 力学過程の変化に足して次のステップを計算する場合には, それらの変化を xyz_DUDtPhy, xyz_DVDtPhy, xyz_DTempDtPhy, xyzf_DQMixDtPhy に与えてください.

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.

Calculate dynamical processes. Input data are Eastward wind (xyz_UB, xyz_UN), northward wind (xyz_VB, xyz_VN), temperature (xyz_TempB, xyz_TempN), mass mixing ratio (xyzf_QMixB, xyzf_QMixN), surface pressure (xyz_PsB, xyz_PsN) at $ t-\Delta t $ and $ t $, and surface height (xy_SurfHeight). Eastward wind (xyz_UA), northward wind (xyz_VA), temperature (xyz_TempA), mass mixing ratio (xyzf_QMixA), surface pressure (xyz_PsA) are returned.

In order to add tendencies of vorticity, divergence, temperature and specific humidity calculated by physical processes other than those by this dynamical process, these tendencies should be given to "xyz_DUDtPhy", "xyz_DVDtPhy", "xyz_DTempDtPhy", "xyzf_DQMixDtPhy"

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. ただし拡散項には後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, physical values at $ t+Delta t $ is calculated from tendency at $ t $ and physical values at $ t-\Delta t $ .

Leap-frog scheme is used as time integration scheme. And backward scheme is used for diffusion terms. As default setting, semi-implicit scheme is applied to gravitational terms in order to enlarge the value of $ Delta t $ . Explicit scheme can be applied to gravitational terms by changing "TimeIntegScheme" in "NAMELIST#dynamics_hspl_vas83_nml".
