Summary of the Article:

**Momentum, Sensible Heat, and Latent Heat Fluxes**

The article discusses the calculations of the following fluxes between the atmosphere and the surface:

1. Zonal and meridional momentum fluxes (τ_x, τ_y)
2. Sensible heat flux (H)
3. Water vapor flux (E)

These fluxes are derived from Monin-Obukhov similarity theory for the surface layer. The key equations are:

- Momentum fluxes:
    τ_x = -ρ_atm * (u_atm - u_s) / r_am
    τ_y = -ρ_atm * (v_atm - v_s) / r_am

- Sensible heat flux: 
    H = -ρ_atm * C_p * (θ_atm - θ_s) / r_ah

- Water vapor flux:
    E = -ρ_atm * (q_atm - q_s) / r_aw

Where r_am, r_ah, and r_aw are the aerodynamic resistances for momentum, sensible heat, and water vapor, respectively.

The article also provides the equation for calculating the atmospheric potential temperature (θ_atm) and the density of moist air (ρ_atm).
