, 2023 Vertical mixing parameterizations in ocean models are formulated on the basis of the physical principles that govern turbulent mixing. However, many parameterizations include ad hoc components that are not well constrained by theory or data.

Increasing the Earth's Albedo: The K\"ohler Equation at Sea
Increasing marine haze and clouds has been considered as a possible means of increasing the Earth's albedo. This would reduce Solar heating and global warming, counteracting the effects of the anthropogenic increase in greenhouse gases.

An Ensemble Machine Learning Approach for Tropical Cyclone Detection Using ERA5 Reanalysis Data
, 2023 Tropical Cyclones (TCs) are counted among the most destructive phenomena that can be found in nature. Every year, globally an average of 90 TCs occur over tropical waters, and global warming is making them stronger, larger and more destructive.

Using Machine Learning for Model Physics: an Overview
, 2020 In the overview, a generic mathematical object (mapping) is introduced, and its relation to model physics parameterization is explained. Machine learning (ML) tools that can be used to emulate and/or approximate mappings are introduced.

Advancing operational PM2.5 forecasting with dual deep neural networks (D-DNet)
PM2.5 forecasting is crucial for public health, air quality management, and policy development. Traditional physics-based models are computationally demanding and slow to adapt to real-time conditions.

Building Ocean Climate Emulators
The current explosion in machine learning for climate has led to skilled, computationally cheap emulators for the atmosphere. However, the research for ocean emulators remains nascent despite the large potential for accelerating coupled climate ...

Substantial Risk of 21st Century AMOC Tipping even under Moderate Climate Change
The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the climate system and considered to be a tipping element. There is still a large uncertainty on the critical global warming level at which the AMOC will start to collapse. Here

Embedding machine-learnt sub-grid variability improves climate model biases
The under-representation of cloud formation is a long-standing bias associated with climate simulations. Parameterisation schemes are required to capture cloud processes within current climate models but have known biases.
