Transition form shallow to deep stormy convection

Deep convection and its parameterization :
\begin{itemize}
\item
Water phase changes play a major role
\item
Existence of an inhibition at the bottom of the convective clouds.
\item
Usually represented through mass flux schemes.
\item
Classical closures rely on the instability of the atmospheric column above condensation level
\end{itemize}

CAPE : Convective Available Potential Energy\\
CIN : Convective INhibition.

In Emanuel (1991) scheme :\\
Triggering : B(LCL + 40hPa) > |CIN|\\
Closure : M$_B$= f(CAPE)
