04.29.2013: LPV analysis of exp33_sponge with reduced time stepΒΆ

Here, I re-perform the LPV analysis for 5 trajectories for exp33_sponge that was re-run for 200 days using half the barotropic and baroclinic time steps. We see that there is almost no difference with previous LPV analyses.

Figure 1: Trajectories over 175 days in exp33_sponge using 1/2-day with DT=1200 s and DTBT=14 s (plain) and with DT=600 s and DTBT=7 s (circles).

Figure 2: LPV analysis for the 5 trajectories highlighted in Fig. 1 using snapshots (plain) or 1-day averages (dash) with 1/2-day output or snapshots 1/2-day output with half the barotropic and baroclinic time steps.


The LPV analysis was done with LPV_analysis_all_time_script.m producing the Matlab file LPV_analysis_alltime_d4015d4215_8E11E_30N_mid_delta_tday_0_5_reduced_timestep_exp33_sponge.mat, all in RESEARCH/MODELISATION/HIM/studies/PV_and_dissipation/forced_damped_wave/exp33_sponge/ on the main disk on ipu1.
