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:

ensType="cf"
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

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 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.
