 The application of boundary conditions is implemented through the operators:
 
 1. For the u-momentum equation:
-   - Top boundary: `Operators.SetValue(FT(ug))` sets u to the geostrophic value
+   - Top boundary: `Operators.SetValue(FT(ug))` sets $u$ to the geostrophic value
    - Bottom boundary: `Operators.SetValue(Geometry.WVector(Cd * u_wind * u_1))` applies the drag condition

-   - Top boundary: `Operators.SetValue(FT(vg))` sets v to the geostrophic value

 This test case is set up in a vertical column domain from $z=0$ m to $z=30$ km with 30 vertical elements. The column is initialized with a decaying temperature profile, where:
 
-- The virtual temperature starts at $T_{virt\_surf} = 280$ K at the surface
-- It asymptotically approaches $T_{min\_ref} = 230$ K with height
+- The virtual temperature starts at $T_{\textrm{virt}\_\textrm{surf}} = 280$ K at the surface
+- It asymptotically approaches $T_{\textrm{min}\_\textrm{ref}} = 230$ K with height
 - The profile follows a hyperbolic tangent function with height
 - The pressure follows a hydrostatic balance equation
 - Density is calculated from the equation of state using virtual temperature and pressure
