A scaling approach to Budyko's framework and the complementary relationship of evapotranspiration in humid environments: case study of the Amazon River basin

Abstract: Abstract. This paper studies a 3-D state space representation of Budyko's framework designed to capture the mutual interdependence among long-term mean actual evapotranspiration (E), potential evapotranspiration (E p ) and precipitation (P ). For this purpose we use three dimensionless and dependent quantities: = E/P , = E p /P and = E/E p . This 3-D space and its 2-D projections provide an interesting setting to test the physical soundness of Budyko's hypothesis. We demonstrate analytically that Budyko-type e… Show more

“…A significant negative relationship between various SM indices and Tx90 has been observed for large parts of Australia, in particular the southeast and north of the country coinciding with the identification of the transitional regime. The main conclusions of this study are the following: Contrary to recent studies [ Greve et al , , ; Carmona et al , ], large parts of the temperate, semiarid, and savanna climate regions in Australia enter the transitional regime and are neither strongly moisture nor radiation limited (Figures a and b). Arid and semiarid regions of Australia exhibit the strongest increase in the quantile regression slopes (from low to high percentiles), indicating that months with low SM is highly likely to experience a large number of Tx90 (Figure ). API appears to best represent patterns seen with the AWAP SM and has the largest anticorrelations with Tx90 in the transitional zone (Figure ). …”

“…The Budyko framework was proposed six decades ago, but new datasets have motivated a recent use of this integrated, elegant and intuitive framework to analyze changes in the land hydrological cycle (e.g. Berghuijs et al 2014, Greve et al 2014, Carmona et al 2016. The Budyko framework distills complex systems to a key effective lumped parameter, which helps to understand and quantify measurements and model features.…”

“…The basin plays a fundamental hydroclimatological role in Earth's climate and exhibits various stability characteristics associated with land cover types and extent (Hirota et al, ; Keller et al, ; Lenton et al, ; Nobre & Borma, ). Understanding the dynamics of the hydrological cycle of the Amazon River basin has been the focus of many previous studies, some interested in individual branches of the hydrological cycle (Costa & Foley, ; Getirana et al, ; Marengo, ; Zeng, ), others in one particular variable of the hydrological budget over the Amazon River basin, such as precipitation in particular seasons (Carlo et al, ; Costa & Foley, ; Liebmann et al, ; Liebmann & Marengo, ; Satyamurty et al, ), runoff (Azarderakhsh et al, ; Coe et al, ; Syed et al, ), evapotranspiration (Carmona et al, ; Hasler & Avissar, ; Mallick et al, ), and wind divergence (Liebmann et al, ; Zeng, ).…”
