Usage of the mean_pressure_weighted function.

[ahmedshaaban1]

All,
This is a follow-up question to the StackOverflow discussion

The mean vertical average could be calculated by using the weighted_continuous_average.

Yet, I am unsure about the problems that might use the mean_pressure_weighted. Could anyone please list a few?

where w(x) is pressure (see this stackoverflow post)
Thanks

I don't see any internal uses of this function any more. I believe it was originally added due to a mis-understanding of Bunkers' storm motion using "pressure-weighted mean".

The function is appropriate when you need an average that is weighted explicitly using the pressure (which is proportional to mass).

Thanks, Just wondering if there it is possible to swap names between the “mean_pressure_weighted” and the “weihgted_continues_average” to match what is already defined in textbooks (Holton(fifth edition, page 86), as below).

That would be a major API change and would cause some confusion. I also have a strong objection to that equation being called "pressure-weighted".

EDIT: To me, that equation above is just "vertical average" (calculated correctly).

Thanks for that reminder @jthielen, that was a helpful trip down memory lane for my own understanding. With any luck it sticks this time.
