Blåhvitt i nord
På eller i Nordpolen? Preposisjoner er vanskelige, særlig når is blir til vann. Denne uken nådde en forskningsekspedisjon Nordpolen med isbryter – lekende lett.

– Hvorfor regner det ikke mer?
Klimaendringer forsterker det verste regnværet mer enn ordinært sipperegn. Ny forskning viser at regn i forbindelse med fronter påvirkes mest, og illustrerer hvorfor annet ekstremregn ikke blir like ille.

Monday seminar 15 Sept: "Role of atmospheric forcing on the North Atlantic dynamic and its robustness in coupled climate".
The next BCCR Monday Seminar will be given by Tillys Petit from the National Oceanographic Centre in the UK. Abstract The Atlantic Meridional Overturning Circulation (AMOC) plays a key role for the Northern Hemisphere climate and, for almost two decades, climate scientists have been concerned with the possibility of a slowing AMOC due to changes in deep water formation over the Labrador and Greenland seas. However, the OSNAP array revealed that the role of deep convection in the Labrador Sea might be overestimated in climate models, which make the future of the AMOC uncertain. To help reconcile these opposing perspectives, I will synthesize my research on the drivers of the North Atlantic dynamic and on their representation in coupled climate models. In a first part, I will review different observation-based estimates of water mass transformation in the subpolar gyre, showing that the deep water is formed primarily in the Irminger and Iceland basins by local buoyancy forcing. A second part will focus on the representation of deep water formation in coupled climate models. These studies shed light on model biases leading to large deep water formation over the Labrador Sea and on their implications for the AMOC at OSNAP latitudes. Finally, a third part will focus on the southward propagation of deep water and on the coherence of the AMOC variability over the North Atlantic. About the speaker Tillys Petit is a Research Scientist at the National Oceanography Centre (UK) specialized in the large-scale ocean circulation and water mass transformation in the North Atlantic. She has done her PhD at IFREMER (France) on the ocean circulation over the eastern subpolar gyre from observations. During her postdoc at Duke University/Georgia Tech (US), she worked on the linkages between buoyancy forcing and volume fluxes at OSNAP, and investigated the connectivity of the AMOC between the subpolar and subtropical gyres from high-resolution models. Then, she continued working on the AMOC and water mass transformation at the University of Reading (UK), but with a focus on the representation of these processes in CMIP-class climate models. She joined the NOC in 2023, where she is developing lower-cost means of observing the AMOC at the RAPID array. She is also co-I on two projects that seek to address gaps in our understanding of Subpolar North Atlantic tipping points.

BCCR Workshop: The Lofoten Basin Eddy in a Regional Context: from Physics to Ecosystem Dynamics
Hi everyone, We are excited to invite you to an exciting workshop on The Lofoten Basin Eddy in a Regional Context: from Physics to Ecosystem Dynamics. The workshop aims to promote the discussion on state-of-the-art research, identify key priorities, and coordinate collaborative efforts to advance our understanding of the dynamics and biogeochemistry of the LBE, and its significance for the regional ecosystems. The event will feature speakers representing initiatives such as NorSWOT, NorGlider, and the PROVOLO project. The complete agenda will follow. When: Wednesday, September 24, 11:30-16:00 Where: BCCR Lecture room, 4th floor Sign up for lunch latest by Monday, September 15: https://forms.gle/qBUetd3AZf25nrWw5 Do you want to present at the workshop? Contact Lucía at lulo@norceresearch.no Best regards, Lucía on behalf of the LBE consortium
