Diagnostics of stratospheric dynamics and chemistry

Overview

This recipe reproduces the figures of Eyring et al. (2006) The following plots are reproduced:

  • Vertical profile climatological mean bias of climatological mean for selected seasons and latitudinal region.

  • Vertical and latitudinal profile of climatological mean for selected seasons this figure and setting is valid for figure 5 (CH4) figure 6 (H2O) figure 11 (HCL) figure 13 (tro3).

  • Total ozone anomalies at different latitudinal band and seasons.

  2. Script <eyring06jgr_fig01.ncl>

    Required settings for script

    • latmin: array of float, min lat where variable is averaged, i.e. [60., 60., -90., -90. ]

    • latmax: array of float,and max lat where variable is averaged, i.e. [90., 90., -60., -60. ]

    • season: array of string., season when variable is averaged, i.e. [“DJF”, “MAM”, “JJA”, “SON”]

    • XMin: array of float, min limit X axis [-30., -30., -30., -30.]

    • XMax: array of float, max limit X axis [20., 20., 20., 20.]

    • levmin: array of float, min limit Y axis [1., 1., 1., 1.]

    Optional settings for script

    • start_year: int, year when start the climatology calculation [1980] (default max among the models start year).

    • end_year:int, year when end the climatology calculation [1999] (default min among the models end year).

    • multimean: bool, calculate multi-model mean, (i.e. False/True) (default False).

    Required settings for variables

    • preprocessor: regrid_interp_lev.

    • reference_dataset: name of the reference model or observation for regridding and bias calculation (e.g. ERA-Interim”).

    • mip: Amon.

Variables

  • ta (atmos, monthly mean, longitude latitude level time)

Fig. 20 Climatological mean temperature biases for (top) 60–90N and (bottom) 60–90S for the (left) winter and (right) spring seasons. The climatological means for the CCMs and ERA-Interim data from 1980 to 1999 are included. Biases are calculated relative to ERA-Interim reanalyses. The grey area shows ERA-Interim plus and minus 1 standard deviation (s) about the climatological mean. The turquoise area shows plus and minus 1 standard deviation about the multi-model mean.
