The Atlantic Is Entering A Cool Phase That Will Change The World’s Weather
IFLSCIENCE | June 1, 2015 | by Gerard McCarthy and Ivan Haigh
The Atlantic Ocean’s surface temperature swings between warm and cold phases every few decades. Like its higher-frequency Pacific relative El Nino, this so-called “Atlantic Multidecadal Oscillation” can alter weather patterns throughout the world. The warmer spell we’ve seen since the late 1990s has generally meant warmer conditions in Ireland and Britain, more North Atlantic hurricanes, and worse droughts in the US Midwest... read more

New Publication in Science of the Total Environment: A study of the hourly variability of the urban heat island effect in the Greater Athens Area during summer
Accepted on 17 February 2015, H. Hooyberghs and B. Maiheu from NACLIM CT4 are the co-authors.
Abstract: Measurements of air temperature and humidity in the urban canopy layer during July 2009 in 26 sites in Athens, Greece, allowed for the mapping of the hourly spatiotemporal evolution of the urban heat island (UHI) effect. City districts neighboring to the mountains to the east were the hottest during the afternoon, while being among the coolest during the early morning hours. While during the early morning some coastal sites were the hottest, the warm air plume slowly moved to the densely urbanized center of the city until 14:00–15:00, moving then further west, to the Elefsis industrial area in the afternoon. Results from the UrbClim model agree fairly well with the observations. Satellite-derived land surface temperature (LST) data from AATSR, ASTER, AVHRR and MODIS, for pixels corresponding to ground stations measuring Tair, showed that LST can be up to 5 K lower than the respective Tair during nighttime, while it can be up to 15 K higher during the rest of the day. Generally, LST during late afternoon as acquired from AATSR is very near to Tair for all stations and all days, i.e., the AATSR LST afternoon retrieval can be used as a very good approximation of Tair. The hourly evolution of the spatial Tair distribution was almost the same during days with NE Etesian flow as in days with sea breeze circulation, indicating that the mean wind flow was not the main factor controlling the diurnal UHI evolution, although it influenced the temperatures attained. No unambiguous observation of the urban moisture excess (UME) phenomenon could be made.

New Publication in Urban Climate: UrbClim – A fast urban boundary layer climate model
By Koen De Ridder, Dirk Lauwaet, Bino Maiheu from CT4, accepted on 07 January 2015.
Abstract: We present a new urban climate model, further referred to as UrbClim, designed to cover agglomeration-scale domains at a spatial resolution of a few hundred metres. This model is composed of a land surface scheme containing simple urban physics, coupled to a 3-D atmospheric boundary layer module. In the land surface scheme, urban terrain is represented as an impermeable slab with appropriate parameter values for albedo, emissivity, and aerodynamic and thermal roughness length, and accounting for anthropogenic heat fluxes. The UrbClim model is subject to several validation exercises, using observations from Toulouse (France), Ghent and Antwerp (Belgium), and Bilbao (Spain), and considering turbulent energy fluxes, wind speed, and urban–rural temperatures. Despite its simplicity, UrbClim is found to be of the same level of accuracy than more sophisticated models, including for the complex terrain characterizing the Bilbao area. At the same time, it is faster than high-resolution mesoscale climate models by at least two orders of magnitude. Because of that, the model is well suited for long time integrations, in particular for applications in urban climate projections.

New Publication in Nature Climate Change: Arctic warming will promote Atlantic–Pacific fish interchange
Published online 26 January 2015, Steffen Olsen from NACLIM CT3 is one of the co-authors. View the article at Nature Online
Warming Arctic enables exchange of fish species among Pacific and Atlantic. [The Carbon Brief] For millions of years, fish species in the Pacific and Atlantic oceans have stuck resolutely to where they belong, kept from venturing between oceans by the cold water of the Arctic.
But new research suggests a warming Arctic could soon see fish putting aside their differences and bridging this chilly divide. And this could have implications for native species and commercial fisheries, the researchers say. Read more [>>]

New Publication in Nature Communications: Wet or dry future Sahel? Difference between extra-tropical and tropical ocean warming will give the answer...
A new study entitled “Northern-hemispheric differential warming is the key to understanding the discrepancies in the projected Sahel rainfall” by Jong-yeon Park, Jürgen Bader und Daniela Matei (CT1) was recently published in Nature Communications. They considered the question of whether the Sahel will be wet or dry in the future and found out that the difference between extra-tropical and tropical ocean warming will be decisive.
The work was financially supported by the German BMBF RACE and MiKlip projects in the frame of an internal MPI-M project Tropical VIBES, with contribution from NACLIM scientist Daniela Matei.

Bluefin tuna caught at east Greenland
Brian MacKenzie (DTU Aqua) "We have recently published a research paper showing that bluefin tuna were present at east Greenland in summer 2012. This location (approx. 65.5 deg. N.) is much farther north than its usual summer feeding habitat, but the warm conditions that year seemed to be suitable for the tuna. The warm water also attracted some of the tuna's favorite prey, such as Atlantic mackerel. This is the first time bluefin tuna have been reported so far north in Greenland water".

New paper on the Arctic–Atlantic Thermohaline Circulation
Eldevik, Tor, Jan Even Ø. Nilsen, 2013: The Arctic–Atlantic Thermohaline Circulation*. J. Climate, 26, 8698–8705. Doi: http://dx.doi.org/10.1175/JCLI-D-13-00305.1 Abstract: The Atlantic Ocean's thermohaline circulation is an important modulator of global climate. Its northern branch extends through the Nordic Seas to the cold Arctic, a region that appears to be particularly influenced by climate change. A thermohaline circulation is fundamentally concerned with two degrees of freedom. This is in particular the case for the inflow of warm and saline Atlantic Water through the Nordic Seas toward the Arctic that is balanced by two branches of outflow. The authors present an analytical model, rooted in observations, that constrains the strength and structure of this Arctic–Atlantic thermohaline circulation. It is found, maybe surprisingly, that the strength of Atlantic inflow is relatively insensitive to anomalous freshwater input; it mainly reflects changes in northern heat loss. Freshwater anomalies are predominantly balanced by the inflow's partition into estuarine and overturning circulation with southward polar outflow in the surface and dense overflow at depth, respectively. More quantitatively, the approach presented herein provides a relatively simple framework for making closed and consistent inference on the thermohaline circulation's response to observed or estimated past and future change in the northern seas.

NACLIM was at the event "The Atlantic- A shared resource" 23-24 May 2013, Galway (Ireland)
Gerard McCarthy (NERC/NOC) represented the NACLIM project at the Galway event.
The objective of this event was to provide a vision for enhanced cooperation on both sides of the Atlantic and a set of jointly agreed priority actions to provide the means to achieve these goals. Recognizing the essential role of international partnership to achieve shared objectives and the potential of greater cooperation to advance our knowledge of the Atlantic Ocean, the Irish Presidency together with the European Commission invited the involvement of international partners in tackling the challenges confronting the citizens of the North Atlantic coastal states. Realising this potential demands not only the ability to make observations and obtain data, but an understanding of ecosystem functioning and interactions and an ability to model, forecast and predict the ocean system.
