I have been trying to get to know how to read atmospheric soundings, but some things remain unclear. I hope someone can clarify.

So if I understand well, as long as T2m < convective temperature, you will need to use the LCL and start the moist adiabatic curve from there to calculate CAPE.

When T2m >= Tcon, you will need to use CCL. Does this mean that the CCL is actually always a LFC (level of free convection), in the meaning that the moist adiabatic curve of the parcel then starts from the intersection of the mixing ratio lapse rate/temperature curve and cannot be placed to the left of the temperature curve in a skew-t/log-p as sometimes happens with the LCL?

What happens when T2m > Tcon? Does this influence the position of the CCL on the sounding and the point from which you have to start the moist adiabatic curve to calculate CAPE compared to the situation where T2m = Tcon?

I hope I made myself clear.

Thanks anyway!
