Selecting CMIP6 Models for Future Arctic Storylines Using a Novel Performance Score
Storylines are physically plausible scenarios of future climate change, statistically derived from an ensemble of climate model projections and organized according to the magnitude of projected changes in two or more remote drivers that strongly influence the spatial pattern of the climate…

Dynamical Emissivity for Microwave Radiance Assimilation in Regional NWP: Preparing for the Arctic Weather Satellite and EPS-Sterna
Radiance observations from microwave sounders have become one of the most valuable sources of information that is used in Numerical Weather Prediction (NWP). However, uncertainties in the land (and sea-ice) surface modelization do not permit optimal use of channels that receive a mixed contribution…

New Beginning for Tellus – An Earth System Science Journal by Scientists for Scientists
Tellus, originally founded in the late 1940s by Carl-Gustaf Rossby, is relaunched as a community-driven Earth system science journal managed by research-active scientists. The new Tellus builds on its historical legacy while responding to the growing need for an integrated understanding of the…

Improving Ocean Reanalysis with the Offline Ensemble Kalman Smoother
The Ensemble Kalman Smoother (EnKS), an extension of the Ensemble Kalman Filter, can improve the accuracy of the state estimate by assimilating ‘future’ observations. We propose to use the EnKS algorithm to enhance the accuracy and reliability of preexisting reanalyses produced with a fully coupled…

Negative Sensitivity of Southern Ocean Circumpolar Transport to Increased Wind Stress Controlled by Residual Overturning
The transport of the Southern Ocean’s Antarctic Circumpolar Current, closely linked to the global stratification to the north and in turn the inter-hemispheric overturning circulation, is a key metric for quantifying ocean circulation. Understanding the sensitivity of transport to changes in…

Aspects of the Global Thermohaline Circulation in the Absence of Wind Forcing
The global ocean’s overturning circulation plays an important role in climate and climate variability through its transport of heat, freshwater and nutrients. As part of this three-dimensional overturning circulation, dense waters sink in narrow regions at high latitudes in the North Atlantic and…

Thermal Recovery Dynamics of the Ocean’s Cool-Skin Layer After Complete Mixing
The air-sea heat exchange has a substantial impact on the heat budget of the surface ocean. Due to the heat loss across the air-sea interface, the uppermost millimeter of the ocean is generally cooler than the underlying water. This cool-skin layer can be naturally disrupted by processes such as…

Assimilation of SEVIRI Water Vapour Radiances in HARMONIE-AROME at Large Satellite Zenith Angles
This study suggests potential benefits in forecast performance by assimilating clear-sky satellite radiances from geostationary based SEVIRI instrument into the limited area model of HARMONIE-AROME in the far North of Europe. The current geographical limitations of assimilating geostationary have…

Exploring Storm Tides Projections and Their Return Levels Around the Baltic Sea Using a Machine Learning Approach
Extreme sea levels are a major global concern due to their potential to cause fatalities and significant economic losses in coastal areas. Consequently, accurate projections of these extremes for the coming century are crucial for effective coastal planning. While it is well established that…

Future Changes of European Windstorm Losses in EURO-CORDEX Simulations
Windstorms are one of the most important natural hazards affecting Europe. This article investigates the potential impacts of climate change on windstorm losses in Europe employing the Loss Index (LI) method. A large EURO-CORDEX multi-model ensemble at 12 km resolution with 20 different general…

Dynamics of Upwelling and Downwelling in a Channel Basin of the Baltic Sea
We consider upwelling and downwelling dynamics in an idealized ocean model configuration of the Western Gotland Basin in the Baltic Sea, featuring a gently sloping bottom in the west and a steep bathymetry in the east. Typical transient wind conditions and seasonally variable stratification are…

Lagrangian View of Atlantic Water Pathways toward the North Sea
The influence of subpolar North Atlantic hydrographic conditions on the North Sea is well recognized, yet the precise pathways taken by Atlantic Water to reach its gateway remain uncertain. Using satellite-derived velocity fields, we map the open-ocean routes leading to the North Sea. Our…

Analytical Formulas for the Structure of Perturbations in the Eady Model of Baroclinic Instability in the 'p'-System
Shortly after World War II, the first two models of baroclinic instability were independently published by Charney (1947) and Eady (1949). Both authors describe the origin and initial development of midlatitude weather disturbances from infinitesimal perturbations of a certain initial state of the…

Self-Adaptive Quantiles for Precipitation Forecasting
How much rain can we expect in Toulouse on Wednesday next week? It is impossible to provide a precise and definitive answer to this question due to the limited predictability of the atmosphere. Ideally, a forecast would be probabilistic, for example expressed in the form of a probability of, say…

Probabilistic Assessment of Future Drought Characteristics under the Quality Boosted Regional Drought Index
Water is one of the most essential components for sustaining human and other forms of life; thus, it must be supplied to meet life’s necessities. Understanding the consequences of global warming and the trends in climate change is essential for the effective operation and strategic planning of…

Chester Newton: Remembrances of his Early Years in Meteorology
Information contained in a 2-hour recorded interview with Chester Newton in 1990 revealed his early experiences and education at the Institute of Meteorology, University of Chicago (1946–1951), and at the International Meteorological Institute (IMI) at Stockholm University (1951–1953). The first…

The Maltese Ocean Front in the Mediterranean Sea: Upwelling and Downwelling and Response to a Strong Wind Event
High-resolution integrated oceanographic observations of the Maltese Ocean Front from unique legacy data of aerial remote sensing, ship, and anchored current meter array and thermistor chains are revisited in an integrated case study. It is shown that significant upwelling and downwelling occurred…

Flow-Dependent Large-Scale Blending for Limited-Area Ensemble Data Assimilation
We propose a method of flow-dependent large-scale blending (LSB) method for limited-area model data assimilation (LAM DA). By incorporating the information from the global model (GM), LSB methods alleviate the large-scale degradation caused by limitations in the domain size and observations. Our…

A Numerical Study of Stochastic El Niño Southern Oscillations Using Wiener Chaos Expansion and Monte Carlo Methods
Stochastic climate models are mathematical representations of the Earth’s climate system that integrate stochastic components to simulate the inherent uncertainties and variability observed in the climate. These models are formed to capture the complex interactions between various elements of the…
