TL;DR: In this article, the authors used a generic physical model based on mass and energy balances to attribute pan evaporation changes to changes in radiation, temperature, humidity and wind speed, and tested the approach at 41 Australian sites for the period 1975-2004.

TL;DR: The pan evaporation paradox is no more than a manifestation of the complementarity between actual evapotranspiration and potential evapOTranspiration (ETp) as mentioned in this paper.

TL;DR: In this paper, the authors use energy balance methods to attribute the observed changes in pan evaporation to changes in the underlying physical variables, namely, radiation, temperature, vapour pressure deficit and wind speed.

TL;DR: The Evaporative Demand Drought Index (EDDI) as discussed by the authors measures the signal of drought through the response of E0 to surface drying anomalies that result from two distinct land surface-atmosphere interactions: a complementary relationship between E0 and ET that develops under moisture limitations at the land surface, leading to ET declining and increasing E0, and parallel ET and E0 increases arising from increased energy availability that lead to surface moisture limitations, as in flash droughts.

TL;DR: Flash droughts are a recently recognized type of extreme event distinguished by sudden onset and rapid intensification of drought conditions with severe impacts as discussed by the authors, and they unfold on subseasonal-to-seasonal timescales (weeks to months).
