Title: Excitation of mixed Rossby-gravity waves by wave-mean flow interactions on the sphere.

The equatorial mixed Rossby-gravity wave (MRGW) is an important contributor
to tropical variability. Its excitation mechanism capable of explaining the
observed MRGW variance peak at synoptic scales remains elusive. This study
investigates wave-mean flow interactions as a [...]

Title: Deep Ensembles to Improve Uncertainty Quantification of Statistical Downscaling Models under Climate Change Conditions.

Recently, deep learning has emerged as a promising tool for statistical
downscaling, the set of methods for generating high-resolution climate fields
from coarse low-resolution variables. Nevertheless, their ability to generalize
to climate change conditions remains q [...]

Title: On the use of Deep Generative Models for Perfect Prognosis Climate Downscaling.

Deep Learning has recently emerged as a perfect prognosis downscaling
technique to compute high-resolution fields from large-scale coarse atmospheric
data. Despite their promising results to reproduce the observed local
variability, they are based on the estimation of independent [...]

Snowing all day, exploring the village and the beautiful artificial snowflakes mounted on the streetlights. After delivering christmas cards I decided to take images of the snow pattern on our friends driveway, where I spotted a well lit #snowflake in the same shape as the artificial one. can you spot it in the second image?

Title: Analysis of persistence-based solar irradiance forecasting benchmarks.

In this work we analyse a set of benchmark methods for solar irradiance
forecasting based on the clear-sky index, namely, persistence, climatology,
smart-persistence and convex combination (CC) of persistence and climatology.
To assess the boundaries of the benchmarks, we include in the analysis [...]

Title: Time-dependent analytic solutions for water waves above sea of varying depths.

We investigate a hydrodynamic equation system which - with some approximation

time-dependent self-similar Ansatz. We found analytic solutions how the wave
height and velocity behave in time and space for constant and linear seabed

Title: Deliquescence probability maps of Mars and key limiting factors using GCM model calculations.

There may be a chance of small-scale ephemeral liquid water formation on
present day Mars, even though the current climate does not support the
existence of larger bodies of water. Through a process called deliquescence,
hygroscopic salts can enter solution by absorbing water vapor directly from t [...]
