Description and evaluation of a new contrail cirrus parameterization in the ARPEGE-Climat atmospheric model Open
The impact of aviation on climate change due to CO 2 emissions is well established and is far less uncertain than the one due to non-CO 2 effects. Among these effects, the formation and evolution of contrails into cirrus-type clouds remain…

Training loss matters: exploring new fit-for-purpose loss combinations for statistical downscaling Open
Deep learning-based statistical downscaling is increasingly adopted in weather and climate science. However, the choice of training loss function, which is central to guiding model optimisation, remains largely unexplored, with most studie…

The role of model background mean state and internal variability in modulating the AMOC response to abrupt CO2 forcing Open
The Atlantic Meridional Overturning Circulation (AMOC) is a critical component of the Earth’s climate system, playing a key role in global heat and carbon transport and influencing both regional and global climate patterns. While the…

Influence of large-scale atmospheric circulation and Mediterranean sea surface temperature to extreme land precipitation: the case of storm Alex Open
Extreme (greater than 500 mm) amount of rain fell in southeastern France and northern Italy on 2nd and 3rd October 2020 during a ‘Mediterranean episode’ triggered by the powerful extratropical cyclone Alex. Here we use a dynamical adjustme…

Description and evaluation of a new contrail cirrus parameterization in the ARPEGE-Climat atmospheric model. Open
The impact of aviation on climate change due to CO2 emissions is well established and is associated with much less uncertainty than the non CO2 effects. Among the non CO2 effects contrails formation and their evolution into cirrus-type clo…
