Title: A multi-modal representation of El Ni\~no Southern Oscillation Diversity.

The El Ni\~no-Southern Oscillation (ENSO) is characterized by alternating
periods of warm (El Ni\~no) and cold (La Ni\~na) sea surface temperature
anomalies (SSTA) in the equatorial Pacific. Although El Ni\~no and La Ni\~na
are well-defined climate patterns, no two events are alike. To dat [...]

Title: Gaussian processes at the Helm(holtz): A more fluid model for ocean currents.

Given sparse observations of buoy velocities, oceanographers are interested
in reconstructing ocean currents away from the buoys and identifying
divergences in a current vector field. As a first and modular step, we [...]

Title: Test experiments with distributed acoustic sensing and hydrophone arrays for locating underwater sound sources.

Whales and dolphins rely on sound for navigation and communication, making
them an intriguing subject for studying language evolution. Traditional
hydrophone arrays have been used to record their acoustic behavior, but opt [...]

Title: A discontinuous Galerkin approach for atmospheric flows with implicit condensation.

We present a discontinuous Galerkin method for moist atmospheric dynamics,
with and without warm rain. By considering a combined density for water vapour
and cloud water, we avoid the need to model and compute a source term for
condensation. We recover the vapour and cloud dens [...]

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: Vertical-slice ocean tomography with seismic waves.

Seismically generated sound waves that propagate through the ocean are used
to infer temperature anomalies and their vertical structure in the deep East
Indian Ocean. These T waves are generated by earthquakes off Sumatra and
received by hydrophone stations off Diego Garcia and Cape Leeuwin. Between
repeating earthquakes, a T [...]

Title: A machine-learning approach to thunderstorm forecasting through post-processing of simulation data.

Thunderstorms pose a major hazard to society and economy, which calls for
reliable thunderstorm forecasts. In this work, we introduce SALAMA, a
feedforward neural network model for identifying thunderstorm occurrence in
numerical weather prediction (NWP) d [...]

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: Towards Learned Emulation of Interannual Water Isotopologue Variations in General Circulation Models.

Simulating abundances of stable water isotopologues, i.e. molecules differing
in their isotopic composition, within climate models allows for comparisons
with proxy data and, thus, for testing hypotheses about past climate and
validati [...]

A critical early stage for the origin of life on Earth may have involved the

to several biomolecules that make up RNA and proteins including [...]
