I’ve gone through the various WRF forums but I am unable to find what I specifically need. I am a bit weak in Fortran, so I am struggling to find answers to the four basic elements (the parcel, the environment, the levels of free convection, and neutral buoyancy) needed to compute CAPE but I guess with enough persistence, I should extract it from the Fortran code that Dennis sent. </div><div dir="ltr"><br></div><div dir="ltr">Prashanth </div><div dir="ltr"><br><blockquote type="cite">On May 4, 2022, at 2:58 PM, Dave Allured - NOAA Affiliate <<a href="mailto:dave.allured@noaa.gov" target="_blank">dave.allured@noaa.gov</a>> wrote:<br></blockquote></div><blockquote type="cite"><div dir="ltr">Prashanth, the CAPE routines were copied from the WRF project.

As a result, I'd like to have control over the various steps in the process and prefer not to directly use the CAPE_3D subroutine. Unfortunately, I can't seem to figure out how to calculate the integral limits viz. the level of free convection and the level of equilibrium. I see that the parcel is defined as the 500 m vertical block within which the various parameters are averaged. Can you please share the code of wrf_cape_3d or explain in algorithmic terms how the environment is defined, and how the two levels that form the integral bounds are computed? <br></div><div style="font-family:garamond,"times new roman",serif"><br></div><div style="font-family:garamond,"times new roman",serif">Thank you, <br></div><div style="font-family:garamond,"times new roman",serif">Prashanth</div></div></blockquote></div></blockquote></div></div>
