How abrupt change in surface temperature impacts water cycle over France ?
2022
Along with the rapid warming tendency of the last decades over France, a shift in air temperaturehas been detected in 1987/88, delimiting two main climate periods from 1959 to 2019. Evidence of pre- andpost-shift runoff seasonal differences suggest an impact of this abrupt warming on water cycle evolution. Asyearly precipitation slightly evolve during the studied period, evapotranspiration appears to be one of themain drivers of the hydrological cycle evolution. Spring is marked by a strong increase in evaporativedemand, followed in summer by a rise in water stress and a drying of soil water content. Besides temporaldisparities, this local water cycle evolution depicts different spatial res…
Évolution du stress gélif et idéotypes de pois d'hiver dans le contexte de changement climatique, à une échelle régionale.

11 pages; International audience; Pea (Pisum sativum L.) is an important crop in temperate regions for its high seed protein concentration that is particularly sensitive to abiotic stresses. The abrupt temperature increase known as the “1987/1988 temperature regime shift” that occurs over Europe is questioning how winter pea will perform in the changing climate. This study assessed the winter frost damage evolution along from 1961 to 2015 in Burgundy-Franche-Comté by using: (1) daily observed and gridded regional temperature data and (2) a validated crop winter frost stress model calibrated for pea. This study shows a global decrease of the frost stress nevertheless resulting from a subtle …
