Convert latent heat flux to evaporation depth

Converts latent heat flux (W/m²) to an evaporation rate in metres per day, suitable for lake water balance calculations.

Usage

flux_to_evap(Qlh, Lv = 2453000, rho_water = 1000)

Arguments

Qlh

Numeric. Latent heat flux (W/m²), should be \(\leq 0\).

Lv

Numeric. Latent heat of vaporisation (J/kg). Default 2453000.

rho_water

Numeric. Water density (kg/m³). Default 1000.

Value

Numeric. Evaporation rate (m/day), \(\leq 0\).

Details

The conversion is: $$E = \frac{Q_{lh}}{L_v\,\rho_w} \times 86400$$
