Prepare initial data (restart data)

初期値データ (リスタートデータ) のサンプルを提供します.

現在は以下のデータを提供します.

  • Small Disturbance of Temperature
    • 風速: 0 [m/s], 地表面気圧: 1.0e+5 [Pa], 比湿: 1.0e-10 [kg kg-1]
    • 温度: 250 [K] に微小擾乱を加えたもの
  • [AGCM 5.3]{www.gfd-dennou.org/library/agcm5} Default
    • 風速: 0 [m/s], 地表面気圧: 1.0e+5 [Pa], 比湿: 1.0e-10 [kg kg-1]
    • 温度: 250 [K] に微小擾乱を加えたもの
  • Sugiyama et al. (2008)
    • 木星大気を想定した, Sugiyama et al. (2008) で用いられていた 初期値を模倣する.
    • 風速: 0 [m/s], 地表面気圧: 3.0e+6 [Pa]
    • 温度: $ sigma = 1 $ で 490 [K] とし, 気圧 1.0e+4 となる高度まで, 温位一定で (乾燥断熱線に沿って) 高度に伴い温度を減少させる. 気圧 1.0e+4 以下の高度では温度一定とする.
    • 比湿: $ sigma = 1 $ で 6.11641e-3 [kg kg-1] とし, 比湿が飽和比湿の 75 % となる高度までは一定とする. その高度以上では, 比湿を飽和比湿の 75 % とする.

Prepare sample data of initial data (restart data)

Now, following data are provided.

  • Small Disturbance of Temperature
    • Velocity: 0 [m/s], Surface pressure: 1.0e+5 [Pa], Specific humidity: 1.0e-10 [kg kg-1]
    • Temperature: 250 [K] and perturbation
  • [AGCM 5.3]{www.gfd-dennou.org/library/agcm5} Default
    • Velocity: 0 [m/s], Surface pressure: 1.0e+5 [Pa], Specific humidity: 1.0e-10 [kg kg-1]
    • Temperature: 250 [K] and perturbation
  • Sugiyama et al. (2008)
    • Initial data like a Jovian atmosphere that is used in Sugiyama et al. (2008) is imitated.
    • Velocity: 0 [m/s], Surface pressure: 3.0e+6 [Pa]
    • Temperature: 490 [K] at $ sigma = 1 $ . And it is declined with constant potential temperature (along dry adiabat line) below where air pressure is 1.0e+4. It is constant above where air pressure is 1.0e+4.
    • Specific humidity: 6.11641e-3 [kg kg-1] at $ sigma = 1 $ . And it is constant below where it is same as 75 % of saturation specific humidity. Above that, specific humidity is 75 % of saturation specific humidity.
