[IDV #XDL-325595]: Error massage when evaluating or running new formula.



Hi Hamdan,

Try his Jython function instead:

def kindex(t850, t700, t500, dp850, dp700):
    """
    k-index according to https://en.wikipedia.org/wiki/K-index_(meteorology)    
    t850 - temperature at 850mb
    t700 - temperature at 700mb
    t500 - temperature at 500mb
    dewp850 - dewpoint at 850mb
    dewp700 - dewpoint at 700mb
    """
    temp850 = make2D(t850)
    temp700 = make2D(t700)
    temp500 = make2D(t500)
    dewp850 = make2D(dp850)
    dewp700 = make2D(dp700)
    kindex = (temp850 - temp500) + dewp850 - (temp700 - dewp700)
    return kindex

Please verify the k-index formula is correct.

Please see here for more information on creating Jython functions/methods and
referring to them with formulas:

> Hi,
> 
> I have problem when i create a new formula of K-Index parameter from
> GFS 3D grib data and it gives an error massage written below:

> Evaluating data choice
> Gridded3DSet.valueToGrid: ManifoldDimension must be 3
