EUREC4A-OA: EUREC4A-OA

Improving the representation of small-scale nonlinear ocean-atmosphere interactions in Climate Models by innovative joint observing and modelling approaches.

EUREC4A-OA will implement ad-hoc innovative observations and a hierarchy of numerical simulations focusing on mesoscale and submesoscale ocean dynamics and the atmospheric boundary layer at scales ranging from 20 m to 1000 km over the northwest tropical North Atlantic. The aim is to advance our knowledge of the phenomenology and representation of air-sea interactions, physical and biogeochemical ocean small-scale non-linear processes in ESMs but also in NWPs, S2Ss and decadal forecasts operational systems.

Wind of (climate) change: More frequent extreme winds over Europe in our future

Stephen Outten and a colleague from NORCE recently published a study on extreme winds over Europe for the remainder of this century, affecting more business sectors than you would think.

KeyCLIM: KeyCLIM

The KeyCLIM project set out to better understand, calculate and reduce the uncertainty related to climate change in Northern Latitudes, especially in the Arctic. The project group has assembled new model scenarios and data documenting large and partly irreversible climate changes in the north for the next 50-300 years.

The projected enhanced warming of the northern latitudes in the forthcoming decades will impact the region’s hydrological cycle, the cryosphere and biogeochemical cycles, impacts which are associated with forecasted, significant changes of the Earth System functioning. It is not clear how the northern world will look like with a summer ice-free Arctic Ocean, changed atmospheric and oceanic circulation patterns and the many specific responses of the Northern Earth system.

ARIA: ARIA - Atmospheric Sea ice interactions in the new Arctic

Arctic cyclones can break up and reshape the Arctic sea-ice cover and can be expected to do so more readily as the ice grows thinner due to anthropogenic climate change. Processes driven by Arctic cyclones can enhance the rate of melting of the ice and increase its export out of the Arctic. We hypothesise that surface coupling (interactions between the ocean, sea ice and atmosphere) play a crucial role in determining the life cycle of Arctic cyclones, and the effect they have on the sea ice.

Processes driven by Arctic cyclones can enhance the rate of melting of the ice and increase its export out of the Arctic. The record minima in sea ice extent in 2012, which was partially attributed to the presence of an Arctic cyclone. However, despite their importance, Arctic cyclones have remained relatively un-examined.

Monsoon rainfall in India – How well do reanalyses compare to real-world data?

NERSC researcher Tarkeshwar Singh (CDP group) recently published an article with colleagues from India. They investigated the performance of three high-resolution atmospheric reanalyses over the Indian region by comparing the rainfall data with focus on the extreme events.

Workshop on climate predictability, in September

This upcoming September, a workshop on climate predictability in the North Atlantic-Arctic sector is planned and the registration is open!

 

What?

Are you working with climate predictability in the North Atlantic-Arctic sector? Then you should consider signing up for this workshop to share your findings and participate in discussions around predictability in that region.

Why?

Correcting biases in NorCPM for the tropical Atlantic with an innovative approach

Several of our Climate Dynamics and Prediction researchers just published a new article in Climate Dynamics, under the lead of François Counillon (NERSC). They showed how reducing model biases can improve seasonal prediction for the tropical Atlantic Ocean.
