Today’s Highlights
High-resolution Earth System Model and convection-permitting regional simulations agree on a robust future intensification of extreme precipitation from mesoscale convective systems across the contiguous US, even as geographic distributions remain model-dependent. On the coast, a new global synthesis finds that tidal range and wave forcing together explain 14–31% of carbon accumulation rate variability in mangroves, marshes, and seagrasses, with contrasting responses that have important implications for carbon-release risk under accelerating sea-level rise.

Evaluation and Future Changes of Mesoscale Convective Systems Over the Conterminous United States in High‐Resolution Global and Regional Simulations

Matched topics: earth system model
Mesoscale convective systems (MCSs) play a central role in producing extreme precipitation over the conterminous United States (CONUS), yet their simulation and future evolution remain elusive. Here we present a comprehensive, observation-constrained evaluation of MCSs during 2001–2020 using multisource satellite and in situ observations, ERA5 reanalysis, high-resolution Community Earth System Model (CESM-HR), and a 4-km convection-permitting regional simulation (CONUS404). CESM-HR faithfully simulates cold-season MCS climatology, structure, and precipitation characteristics, with heavy precipitation dominated by resolved-scale modeling processes. CONUS404 better captures warm-season MCS precipitation intensity but tends to produce more compact systems. Despite differences in historical performance, both CESM-HR and CONUS404 project intensified MCS-related extreme precipitation, expanded spatial extent, increased frequency by the mid–twenty-first century, indicating a robust response to warming. In contrast, projected future changes in MCSs geographic distributions and lifetime duration remain model dependent, highlighting the continued challenges in constraining the dynamical aspects of MCS evolution.

Coastal blue-carbon burial is vulnerable to climate change, yet marine hydrodynamic effects remain poorly quantified. Here we estimate hydrodynamic effects on carbon accumulation rate (CAR), by integrating global observations across mangroves, marshes and seagrasses with multiple drivers. Across all ecosystems, hydrodynamics explains 11.8–16.2% of CAR variability, whereas within individual ecosystems it explains 14.5–31.4%, 13.2–13.9% and 14.7–17.7% in mangroves, marshes and seagrasses, respectively. Limited tidal ranges leave low-CAR, inundation-tolerant seagrasses more common, whereas larger tidal ranges support broader intertidal habitats for high-CAR mangroves and marshes. Wave forcing shows contrasting relationships with CAR: positive in mangroves and seagrasses, potentially linked to organic matter inputs, but negative in marshes, likely reflecting lateral export. As sea-level rise accelerates and storms intensify, carbon-release risks may become heterogeneous, with marshes most vulnerable and mangroves and seagrasses more conditional and regionally uncertain. These findings provide a hydrodynamic framework for predicting future carbon dynamics.
