How to Write IVT equation in PostWRF #49

Closed LJroy1998 closed 2 months ago

LJroy1998 commented 2 months ago

@anikfal I was trying by using this approach For first two levels, i have taken the average q, u, v, and compute qu and qv for it. similarly, for the second and third level, and so on to the last level. All all the qu values over all the levels to get integrated vapor flux in u direction, call it QU. (I have also multiply the entire terms by 1/g to make is flux in kgm-1-1). Similalrly, i find the integrated flux in v direction QV. After this, i have taken the square root of the QU and QV vector to give you IVT. But still it not there if you have derived some equation already please help me in that.

Sorry I am not sure what you are talking about. Does IVT stand for the Intermediate Value Theorem? Please clarify in more details, providing namelist.wrf if you are using PostWRF.

I am talking about Intrgrated vapour transport equation how to write that into PostWRF. I am attaching the IVT equation and the namelist.wrf file. namelist.wrf.docx IVT

Integrals are not supported by PostWRF. Only polynomials with the main mathematical operations (addition, multiplication, etc.) can be put into namelist.wrf.

okay, thank you for your help.
