Abstract
The Budyko functions B1(Φp) are dimensionless relationships
relating the ratio E / P (actual evaporation over precipitation) to the
aridity index Φp = Ep / P (potential evaporation over
precipitation). They are valid at catchment scale with Ep
generally defined by Penman's equation. The complementary evaporation (CE)
relationship stipulates that a decreasing actual evaporation enhances
potential evaporation through the drying power of the air which becomes
higher. The Turc–Mezentsev function with its shape parameter λ,
chosen as example among various Budyko functions, is matched with the CE
relationship, implemented through a generalised form of the
advection–aridity model. First, we show that there is a functional
dependence between the Budyko curve and the drying power of the air. Then, we
examine the case where potential evaporation is calculated by means of a
Priestley–Taylor type equation (E0) with a varying coefficient
α0. Matching the CE relationship with the Budyko function leads to
a new transcendental form of the Budyko function B1′(Φ0) linking
E / P to Φ0 = E0 / P. For the two functions B1(Φp) and
B1′(Φ0) to be equivalent, the Priestley–Taylor coefficient
α0 should have a specified value as a function of the
Turc–Mezentsev shape parameter and the aridity index. This functional
relationship is specified and analysed.
