Effects of varying shape of the initial perturbation on the geostrophic adjustment experiment
I will give a summary talk on two published works which are pointing out the importance of the initial perturbation on the geostrophic adjustment experiment. From the first perspective (Rostami&Zeitlin, 2019), the experiment was repeated for dry and moist-convective cases. On this work, they showed how the western part is affected with varying the initial perturbation shape in the long-wave dynamics. In addition to this, they observed that an intense twin dipole emerges with changing the amplitude of the perturbation. On the second work (Coutino&Stastna, 2017), they investigated how the kinetic energy-potential energy ratio changes with different initial perturbation.
While giving this talk, I will share some results for mainly focusing on the first perspective that I obtained from TIGAR software.
