Title: Improving the representation of the atmospheric boundary layer by direct assimilation of ground-based microwave radiometer observations.

In a joint effort, MeteoSwiss and Deutscher Wetterdienst (DWD) address the
need for improving the initial state of the atmospheri [...]

Title: Postprocessing of Ensemble Weather Forecasts Using Permutation-invariant Neural Networks.

Statistical postprocessing is used to translate ensembles of raw numerical
weather forecasts into reliable probabilistic forecast distributions. In this
study, we examine the use of permutation-invariant neural networks for this
task. In contrast to previous approache [...]

Title: Limits to predictability of the asymptotic state of the Atlantic Meridional Overturning Circulation in a conceptual climate model.

Anticipating critical transitions in the Earth system is of great societal
relevance, yet there may be intrinsic limitations to their predictability. For
instance, from the theory of dynamical systems possessing multiple chaotic
attractors, it is known t [...]

Title: Interpreting Observed Interactions between Near-Inertial Waves and Mesoscale Eddies.

The evolution of wind-generated near-inertial waves (NIWs) is known to be
influenced by the mesoscale eddy field, yet it remains a challenge to
disentangle the effects of this interaction in observations. NIWs are often
modeled using a slab mixed-layer model with no horizontal structure. Here, the
the [...]

Title: From trees to rain: Enhancement of cloud glaciation and precipitation by pollen.

The ability of pollen to enable the glaciation of supercooled liquid water
has been demonstrated in laboratory studies; however, the potential large-scale
effect of trees and pollen on clouds, precipitation and climate is pressing
knowledge to better understa [...]

Title: Connecting finite-time Lyapunov exponents with supersaturation and droplet dynamics in the bulk of a turbulent cloud.

The impact of turbulent mixing on the droplet size distribution is studied
deep inside a warm ice-free cloud. A simplified cloud mixing model was
implemented therefore which summarizes the balance equations of water vapor
mixing ratio and temperature to an effective advection- [...]

Title: Wave Sequential Data Assimilation in Support of Wave Energy Converter Power Prediction.

Integration of renewable power sources into grids remains an active research
and development area, particularly for less developed renewable energy
technologies such as wave energy converters (WECs). WECs are projected to have
strong early market penetration for [...]

Title: Modeling wind-responsive diurnal sea surface temperature for cloud-resolving simulations.

The diurnal variability of sea surface temperature (SST) may play an
important role for cloud organization above the tropical ocean, with
implications for precipitation extremes, storminess, and climate sensitivity.
Recent cloud-resolving simulations demonstrate how imposed diurnal SST
oscill [...]

Title: Teleconnection patterns of different El Ni\~no types revealed by climate network curvature.

The diversity of El Ni\~no events is commonly described by two distinct
flavors, the Eastern Pacific (EP) and Central Pacific (CP) types. While the
remote impacts, i.e. teleconnections, of EP and CP events have been studied for
different regions individually, a glob [...]

Title: Seasonality and spatial dependence of meso- and submesoscale ocean currents from along-track satellite altimetry.

Along-track wavenumber spectral densities of sea surface height (SSH) are
estimated from Jason-2 altimetry data as a function of spatial location and
calendar month, to understand the seasonality of meso- and submesoscale
balanced dynamics across the global ocean. Regions with significa [...]

Title: Definition, detection, and tracking of persistent structures in atmospheric flows.

Long-lived flow patterns in the atmosphere such as weather fronts,
mid-latitude blockings or tropical cyclones often induce extreme weather

Title: What do large-scale patterns teach us about extreme precipitation over the Mediterranean at medium- and extended-range forecasts?.

Extreme Precipitation Events (EPEs) can have devastating consequences such as
floods and landslides, posing a great threat to society and the economy.
Predicting such events long in advance can support the mitigation of n [...]
