Short summary
Short summary
We compare resolved gravity wave drag from high-resolution reanalysis data with parameterized drag from global climate model simulations. Our results show strong similarity between parameterized and resolved drag, but their interactions with Rossby waves differ markedly. This discrepancy suggests that current climate models may misrepresent gravity wave influences on atmospheric circulation and highlight the need to improve gravity wave parameterizations for more reliable climate predictions.

In this work, we compute and analyze resolved gravity wave drag in high-resolution reanalysis data. Studying gravity waves with a realistic dataset helps us to understand them better and potentially improve climate projections. Part of our results supports a key hypothesis governing the vertical distribution of parameterized gravity wave drag in climate models; however, we also provide evidence of the strong influence of horizontal wave propagation, a mechanism that is currently missing in the models.

The phenomena of meteors occurs at altitudes of 60–120 km and can be used to measure the neutral atmosphere. We use a large high power radar system in Norway (Middle Atmosphere Alomar Radar System (MAARSY)) to measure the meteors and determine changes to the atmospheric density between the years of 2016–2023 at altitudes of 85–115 km. The same time period between years are compared, minimizing changes to the measurements due to factors other than the atmosphere.

Gravity waves are small-scale processes that drive the circulation in the middle and upper atmosphere. In this work, we assess 3 new high-resolution (3-5km horizontal resolution) models against satellite data. Generally, models capture the spatial patterns and represent stratospheric northern hemisphere mountain generated waves well. However, they still underestimate amplitudes globally and struggle with the representation of southern hemispheric convective waves.

This review explains how weather patterns, guided by the polar jet stream, influence the Baltic Sea’s climate and ecosystem. It covers the North Atlantic Oscillation, blocking events and other processes and discusses how they affect temperature, rainfall, and storms from days to decades. These shifts then impact oxygen levels, productivity, and acidification in the Baltic Sea. Physical links are fairly well known, but biogeochemical pathways remain uncertain.

We present co-occurrence of gravity waves (GWs) and vertical shear in the North Atlantic lowermost stratosphere using ERA5 reanalysis data. Our results suggest the importance of GWs in the formation and maintenance of tropopause shear layer and ultimately to the potential turbulence occurrence in the extratropical upper troposphere lower stratosphere (UTLS). Overall, small-scale processes, and in particular, GWs can have larger implications for dynamics and composition in the UTLS.

This study improves how we predict ice formation in clouds by accounting for variable ice sizes and different weather conditions. Using simulations, we developed a more accurate method that works efficiently, making it suitable for application in weather and climate prediction models. The new approach is numerically verified and provides precise predictions of ice formation events and reliable estimates of key parameters.

We present the Icosahedral Nonhydrostatic (ICON) general circulation model with an upper-atmospheric extension with the physics package for numerical weather prediction (UA-ICON(NWP)). We optimized the parameters for the gravity wave parameterizations and achieved realistic modeling of the thermal and dynamic states of the mesopause regions. UA-ICON(NWP) now shows a realistic frequency of major sudden stratospheric warmings and well-represented solar tides in temperature.

Understanding how greenhouse gases and pollutants move through the atmosphere is crucial. A new model, the Boundary Layer Dispersion and Footprint Model (BLDFM), tracks their movement. Unlike previous models, BLDFM uses a numerical approach without simplifying assumptions. It's flexible and can be used for climate impact studies and industrial emissions monitoring. Our testing and comparison results show BLDFM's potential as a valuable research tool.

Tropical precipitation cluster area and intensity distributions follow power laws, but the physical processes responsible for this behavior remain unknown. We analyze global simulations that realistically represent precipitation processes. We consider Earth-like planets as well as virtual planets to realize different types of large-scale dynamics. Our finding is that power laws in Earth’s precipitation cluster statistics stem from the robust power laws in Earth’s atmospheric wind field.

The quasi-biennial oscillation, which governs the tropical stratospheric circulation, is driven primarily by small-scale wave processes. We employ a novel method to realistically represent these wave processes in a global model, thereby revealing an aspect of the oscillation that has not been identified before. We find that the oblique propagation of waves, a process neglected by existing climate models, plays a pivotal role in the stratospheric circulation and its oscillation.

Models of the Earth system used to understand climate and predict its change typically employ a grid spacing of about 100 km. Yet, many atmospheric and oceanic processes occur on much smaller scales. In this study, we present a new model configuration designed for the simulation of the components of the Earth system and their interactions at kilometer and smaller scales, allowing an explicit representation of the main drivers of the flow of energy and matter by solving the underlying equations.

Short summary
The EUREC4A field campaign, designed to test hypothesized mechanisms by which clouds respond to warming and benchmark next-generation Earth-system models, is presented. EUREC4A comprised roughly 5 weeks of measurements in the downstream winter trades of the North Atlantic – eastward and southeastward of Barbados. It was the first campaign that attempted to characterize the full range of processes and scales influencing trade wind clouds.

Short summary
The study analyzes gravity waves in a high-resolution simulation. A unique methodology is applied to compute three-dimensional gravity wave spectra while keeping the data on the original triangular model grid and using linear wave theory. The results show the structure of gravity waves that would remain unresolved by a model with lower horizontal resolution. It is shown that the spectra can be highly simplified, which can help constructing precise but efficient gravity wave parametrisation.
