[gradsusr] Minimum MSLP over both time and ensemble

[mike at weatherwatch.net.au]

Hi all,

 

I have the following example which works fine for a single time step for
multiple ensemble members:

 

'q file'

sizes = sublin(result,5)

esize = subwrd(sizes,15)

 

'set t 1'

'set e 1 'esize

'define tl = const( const( maskout(PRMSLmsl/100, 996-PRMSLmsl/100), 1), 0,
-u)'

'define percentagetl = (100 * ave(tl, e=1, e='esize')) + (lon/10000)'

'd percentage1l'

 

How would I go about doing the same as above but instead of a single time
step, do a time series like (eg set t 1 7 to get the min mslp value over a
24 hour period for all ensemble members)

 

Cheers, Mike
