Key Equations

$$\text{CAPE} = \int_{\text{LFC}}^{\text{EL}} g \, \frac{T_{v,\text{parcel}} - T_{v,\text{env}}}{T_{v,\text{env}}} \, dz$$
$$T_v = T \left(1 + 0.608 \, q - q_l\right)$$
$$\text{SRH} = \int_0^h (\mathbf{V} - \mathbf{c}) \cdot \left(\frac{\partial \mathbf{V}}{\partial z} \times \hat{k}\right) dz$$
$$\frac{\partial \zeta}{\partial t} = \underbrace{\omega_h \cdot \nabla_h w}_{\text{tilting}} + \underbrace{\zeta \frac{\partial w}{\partial z}}_{\text{stretching}} + \underbrace{\frac{1}{\rho^2}(\nabla\rho \times \nabla p) \cdot \hat{k}}_{\text{baroclinic}}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
