Long-term hail risk assessment with deep neural networks
, 2022 Hail risk assessment is necessary to estimate and reduce damage to crops, orchards, and infrastructure. Also, it helps to estimate and reduce consequent losses for businesses and, particularly, insurance companies.

Shallow Cumulus Cloud Fields Are Optically Thicker When They Are More Clustered
, 2023 Shallow trade cumuli over subtropical oceans are a persistent source of uncertainty in climate projections. Mesoscale organization of trade cumulus clouds has been shown to influence their cloud radiative effect (CRE) through cloud cover.

Topological Signature of Stratospheric Poincare -- Gravity Waves
, 2023 The rotation of the earth breaks time-reversal and reflection symmetries in an opposite sense north and south of the equator, leading to a topological origin for certain atmospheric and oceanic equatorial waves. Away from the equator the rotating shallow

Southern Ocean Dynamics Under Climate Change: New Knowledge Through Physics-Guided Machine Learning
, 2023 Complex ocean systems such as the Antarctic Circumpolar Current play key roles in the climate, and current models predict shifts in their strength and area under climate change.

, 2023 We describe CATKE, a parameterization for ocean microturbulence with scales between 1 and 100 meters. CATKE is a one-equation model that predicts diffusive turbulent vertical fluxes a prognostic turbulent kinetic energy (TKE) and a diagnostic mixing ...

Global Cascade of Kinetic Energy in the Ocean and the Atmospheric Imprint
, 2023 We present the first estimate for the ocean's global scale-transfer of kinetic energy (KE), across scales from 10~km to 40000~km. We show the existence of oceanic KE transfer between gyre-scales and mesoscales induced by the atmosphere's Hadley, Ferrel ...

A Model for the Tropical Cyclone Wind Field Response to Idealized Landfall
, 2022 The impacts of a tropical cyclone after landfall depend not only on storm intensity but also on the size and structure of the wind field. Hence, a simple predictive model for the wind field after landfall has significant potential value.

Data Driven modelling of Sea Ice Drift [PDF]
We develop a realistic simulation of sea ice drift and deformation using machine learning (ML) techniques as an alternative to traditional physics-based numerical models.

Invariants and chaos in the Volterra gyrostat without energy conservation
, 2022 The model of the Volterra gyrostat (VG) has not only played an important role in rigid body dynamics but also served as the foundation of low-order models of many naturally occurring systems.
