The Cold-Air Outbreaks in the Marine Boundary Layer Experiment model-observation intercomparison project (COMBLE-MIP) – Part 1: Model specification, observational constraints, and preliminary findings

Models struggle to represent the coupled microphysical, turbulent and radiative processes within widespread, long-lived marine cold-air outbreak (CAO) cloud fields, contributing to forecast and climate biases. Here we combine ground-based and satellite measurements to initialize...

How Good Is Your Forecast? The Importance of User‐Centred, Decision‐Relevant Evaluation of Forecasts and Climate Services

ABSTRACT Forecasts and climate services, spanning weather and climate timescales, play a vital role in supporting short‐ and long‐term decision‐making across a wide range of climate‐sensitive sectors. Understanding their skill is crucial to ensuring that the information provided...

Trends in Heat Stress During Heat Waves Across Europe (1979–2023)

Abstract With heat waves becoming more frequent and intense under global warming, heat stress is a growing public health risk. We analyze heat stress trends (Simplified Wet Bulb Globe Temperature, sWBGT) during European heatwaves (1979–2023) using observations and reanalysis data...
