We can define the gradients $\nabla \equiv \frac{\D \ln \T}{\D \ln \P}$ and $\nabla' \equiv \frac{\D \ln \T'}{\D \ln \P}$. Here $\nabla$ represents the average temperature gradient with respect to pressure of all matter at a given level, while $\nabla'$ is the temperature gradient with respect to pressure of a rising/falling fluid element.
At first order the temperature excess of such fluid elements can therefore be written as
\begin{equation}
\Delta \T = \T'(r + \Delta r) - \T(r + \delta r) \simeq \Delta r
\Bigg[ \bigg[ \frac{\D \T'}{\D r}-\frac{\D \T}{\D
r}\Bigg] r}\bigg]
\end{equation}
