Advancing the microphysical and subgrid treatment of precipitation in the LMDZ AGCM: parametrization development and first applications in polar contexts

A crucial role of land-atmosphere interactions in shaping subseasonal convective variability over the Maritime Continent in idealized model simulations

The limitations of current Earth system models in accurately representing the propagation of the Madden-Julian Oscillation (MJO) over the Maritime Continent (MC) significantly hinder our ability to make skillful subseasonal-to-seasonal predictions of extreme weather events worldwide. Additionally, our understanding o...

The role of secondary ice production in shaping the microphysical evolution of orographic clouds: A RAMS-ICLAMS modeling study

Refining the Simulation of Mixed‐Phase Clouds Over Coastal Antarctica With a Tailored Ice Nucleating Particle Parameterization

Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land versi...

Evaluation of Riming in the P3‐2ice Microphysics Scheme: A Case Study of Cold‐Air Outbreak Snowfall in Eastern China

Using the multi‐frequency radar suite, ground‐based observations, and the Weather Research and Forecasting (WRF) model with the Predicted Particle Properties microphysics scheme with the version of two‐ice category (P3‐2ice), we study the characteristics of a cold‐air outbreak (CAO) snowfall event on 6–7 December 2024....

Dry snow initialization and densification over the Greenland and Antarctic ice sheets in the ORCHIDEE land surface model

Moist convection and water vapour transport into the upper troposphere over the Third Pole in multi-scale ICON-CLM simulations

Water vapour exchange into the upper troposphere (UT) remains poorly understood over the Third Pole region. Previous studies have mainly focused on monsoon related moistening of the UT using reanalysis and satellite data. In this study, we employ km-scale (Dx = 3.3 km) ICON-CLM simulations to investigate the role of co...
