It is clear that the first derivative of (\autoref{eq:stab_func_eqn}), 104 and thus of (\autoref{eq:ecmwf1}), is discontinuous at $\zeta=0$ (\ie $Q\rightarrow0$ in104 and thus of (\autoref{eq:ecmwf1}), is discontinuous at $\zeta=0$ (\ie\ $Q\rightarrow0$ in 105 105 equation (\autoref{eq:ecmwf2})). 106 106
