Panel
titleUse ens_to_an_diff to compare an ensemble member to the analysis

 To animate the difference in MSLP of an individual ensemble member 30 to the analysis, edit the lines:

Code Block
param="mslp"
ensType="pf30"

To compare the control forecast:

Code Block
ensType="cf"

 

Further analysis using ensembles

 

Panel
titleUse pf_to_cf_diff.mv to compare two ensemble members to the control forecast

This will show the forecasts from the ensemble members and also their difference with the ensemble control forecast.

To animate the difference in MSLP with ensemble members '30' and '50', set:

Code Block
param="mslp"
pf=[30,50]
Panel
titleCross-sections of ensemble members

To show a cross-section of a particular ensemble member, use the macro 'ens_xs.mv'.

This works in the same way as the an_xs.mv and hres_xs.mv macros.

Panel
titleIdentifying sensitive region for better forecasts

Find ensemble members that appear to produce a better forecast and look to see how the initial development in these members differs.

  • Select 'better' forecasts using the stamp plots and use ens_to_an.mv to modify the list of ensembles ensemble plots. Can you tell which area is more sensitive for the forecast?
  • Use pf_to_cf_diff and ens_to_an_diff to take the difference between these perturbed ensemble member forecasts from the control and analyses to also look at this.
