This study focuses on future very hot summers associated with severe heatwaves and record-breaking temperatures in France. Daily temperature observations a pair of historical scenario (greenhouse gas radiative concentration pathway 8.5) simulations the high-resolution (∼12.5 km) ALADIN regional climate model provide robust framework to examine spatial distribution these extreme events their 21st century evolution.
Abstract. Building on CMIP6 climate simulations, updated global and regional observations, recently introduced statistical methods, we provide an assessment of past future warming over France. Following the IPCC AR6 recent global-scale studies, combine model results with observations to constrain change at scale. Over mainland France, forced in 2020 respect 1900–1930 is assessed be 1.66 [1.41 1.90] ∘C, i.e., upper range estimates, almost entirely human-induced. A refined view seasonality...
Abstract. In early April 2021 several days of harsh frost affected central Europe. This led to very severe damage in grapevine and fruit trees France, regions where young leaves had already unfolded due unusually warm temperatures the preceding month (March 2021). We analysed with observations 172 climate model simulations how human-induced change this event over many vineyards are located. found that, without human-caused change, such or later spring would have been even lower by 1.2 ∘C...
State-of-the-art climate models project a substantial decline in precipitation for the Mediterranean region future1. Supporting this notion, several studies based on observed data spanning recent decades have suggested decrease precipitation2–4, with some attributing large fraction of change to anthropogenic influences3,5. Conversely, certain researchers underlined that exhibits considerable spatiotemporal variability driven by atmospheric circulation patterns6,7 maintaining stationarity...
In order to estimate observed warming, many studies rely on linear trends with uncertainty ranges derived using a white noise assumption the residuals. Here, we assess extent which these two very rough assumptions – that change is in time and internal variability (IV) can be used warming accurately. While such general issues have been widely discussed statistics, this article provides few practical recommendations for use climate data. First, impact of different regarding temporal shape...

Abstract. For many years real-time climate monitoring for temperature over France has been performed using a national index built by averaging the daily mean temperatures of constant subset 30 stations with long-term series. In order to derive indices at finer scales, spatialization extreme (called ANASTASIA) had produced on 1 km regular grid regression-kriging method. The production covers 1947 present period. Cross-validation shows low biases after 1960s. temporal homogeneity product is...

High quality and well-managed climate data are the cornerstone of all services. Consistently assessing how well managed is one way to establish or demonstrate trustworthiness data. This paper presents World Meteorological Organization’s (WMO) Stewardship Maturity Matrix for Climate Data (SMM-CD) subsidiary SMM-CD National Regional Purposes (SMM-CD_NRP). Both these matrices have been developed with support WMO its High-Quality Global Management Framework (HQ-GDMFC). These self-assessment...
The studies previously realized at the Climatology Department of Météo-France allowed characterizing mean climate change. But one major concerns with a potential change in is evolution extremes. study presented here part GICC/IMFREX project. In this project, daily reference series were constituted. These complete monthly homogenized already available for study. Climate indices then calculated on these series.The temperature show pronounced warming over second half 20th century. trends...
Les séries climatiques quotidiennes de référence permettent caractériser l'évolution des valeurs extrêmes en France. Tous les indices température sur la période 1951-2000 traduisent un réchauffement marqué et traces d'augmentation variabilité sont repérées pour températures maximales. tendances précipitations moins systématiques, mais on relève l'augmentation sécheresses estivales l'allongement périodes pluvieuses.
An updated assessment of past and future warming over France
Les forêts de l’Est la France ont subi gros dégâts au cours période 2015 à 2020 du fait récurrence d’événements extrêmes sécheresse et vagues chaleur. Cet article vise qualifier le caractère exceptionnel ces événements partir des meilleurs jeux données climatiques disponibles indicateurs pertinents pour forêt. Le lien avec changement climatique, plus en évident depuis quelques années, est établi quantifié travers les approches détection d’attribution. Messages clésLa répétition sécheresses...
