Short summary
This study evaluated how updating land cover maps, such as forests, grasslands, and croplands, affects simulations of snow and land surface temperatures across Europe from 2010 to 2022. Results using older, less detailed maps were compared with those from newer, high-resolution data. The updated maps improved the accuracy of snow predictions, particularly in areas where grasslands transitioned to forests. However, the improvements were less noticeable for temperature simulations.

We investigate the link between European meteorological droughts and persistent year-round weather regimes derived from mid-tropospheric circulation. Using a novel regionalization based on drought synchronicity and reanalysis data, we show that regime frequency anomalies partly explain drought occurrence, especially in western Europe and in winter, highlighting both the potential and limits of regime-based drought prediction.

We demonstrate the capability of a global operational system to predict seasonal river discharges by accounting for interactions between the atmosphere, ocean, land and rivers. The fully coupled approach introduces a convenient single-step workflow, allowing the simultaneous production of atmospheric and streamflow forecasts. Overall, the approach outperforms the classical ensemble streamflow prediction approach, providing insight into the next-generation hydrological forecasting systems.

Triple oxygen isotopes (17O-excess) are an upcoming tool in hydrological studies. We present the first one-year high-resolution record of 17O-excess in atmospheric water vapor from a Mediterranean forest site. The dataset provides insights into the processes driving variability of 17O-excess in atmospheric water vapor and precipitation across seasonal, diurnal, and event scales. These findings support model validation efforts and enhance the interpretation of paleoclimate archives.

Sudden Stratospheric Warmings (SSWs) are known to follow a sustained wave dissipation in the stratosphere, which depends on both the tropospheric and stratospheric states. However, the relative role of each state is still unclear. Using a new set of subseasonal to seasonal forecasts, we show that the stratospheric state does not drastically affect the precursors of three recent SSWs, but modulates the stratospheric wave activity, with impacts depending on SSW features.

We reassess the basis for determining the present level of long-term global warming. Unbiased estimates of both realised warming and anthropogenic warming are possible that approximate a 20-year retrospective mean. Our resulting estimates of 1.40 [1.23–1.58] °C (realised) and 1.34 [1.18–1.50] °C (anthropogenic) as at end of 2024 highlight the urgency of immediate, far-reaching and sustained climate mitigation actions if we are to meet the long term temperature goal of the Paris Agreement.

Near-term climate change projections are strongly affected by the uncertainty from internal climate variability. Here, we present a novel approach to reduce this uncertainty by combining information from both observations and decadal predictions to constrain climate projections. This new method can outperform decadal predictions and unconstrained ensemble temperature forecasts in some regions. This improved regional climate information could support more near-term targeted adaptation strategies.

In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. Here we compile monitoring datasets to track real-world changes over time. To make our work relevant to policymakers, we follow methods from the Intergovernmental Panel on Climate Change (IPCC). Human activities are increasing the Earth's energy imbalance and driving faster sea-level rise compared to the IPCC assessment.

CSTools (short for Climate Service Tools) is an R package that contains process-based methods for climate forecast calibration, bias correction, statistical and stochastic downscaling, optimal forecast combination, and multivariate verification, as well as basic and advanced tools to obtain tailored products. In addition to describing the structure and methods in the package, we also present three use cases to illustrate the seasonal climate forecast post-processing for specific purposes.

This paper describes an experimental protocol focused on sudden stratospheric warmings to be carried out by subseasonal forecast modeling centers. These will allow for inter-model comparisons of these major disruptions to the stratospheric polar vortex and their impacts on the near-surface flow. The protocol will lead to new insights into the contribution of the stratosphere to subseasonal forecast skill and new approaches to the dynamical attribution of extreme events.

Short summary
Forecasting temperature patterns beyond 2 weeks is very challenging, although occasionally, forecasts show more skill over Europe. Our study indicates that the level of skill varies concurrently for two distinct forecast systems. It also shows that higher skill occurs when forecasts are issued during specific patterns of atmospheric circulation that tend to be particularly persistent.
These results could help forecasters estimate a priori how trustworthy extended-range forecasts will be.
