Denver, Sept. 06: it is midday and Jonathan and Maria are sunbathing at City Park. They feel uncomfortable as the temperature has already reached 36°C. While they decide to go back home, their favoured weather app displays an unbelievable snowstorm watch for Tuesday Sept. 08. The forecast turns out to be rather accurate as all …[Read More]

NPG Paper of the Month: “Correcting for model changes in statistical postprocessing – an approach based on response theory”
This month the NPG Paper of the Month award is achieved by Jonathan Deameyer and Stéphane Vannitsem for their paper “Correcting for model changes in statistical postprocessing – an approach based on response theory” (https://doi.org/10.5194/npg-27-307-2020). Jonathan did his PhD in statistical mechanics at the Université Libre de Bruxelles under the supervision of Pierre Gaspard and …[Read More]
NPG Paper Highlight: “Baroclinic and barotropic instabilities in planetary atmospheres: energetics, equilibration and adjustment”
Today’s our blog hosts a review article by the 2016 EGU Richardson medallist Peter Read, together with Daniel Kennedy, Neil Lewis, Hélène Scolan, Fachreddin Tabataba-Vakili, YixiongWang, Susie Wright, and Roland Young for the special issue of NPG celebrating 100 years of IUGG (https://npg.copernicus.org/articles/27/147/2020/npg-27-147-2020.html). One of the great achievements of the past 100 years in fluid …[Read More]
Is planting trees a feasible large-scale solution to mitigate climate change?
In the last few years it has become a common practice to compensate carbon dioxide (CO2) emissions by planting trees. This idea is simple and rooted on a very basic principle: trees get the energy of sunlight, and by photosynthesis they take water from the ground and CO2 from the air, releasing oxygen in the …[Read More]
How Climate Sciences can help in understanding uncertainties in Covid-19 epidemic projections
COVID-19 is currently affecting over 180 countries in the world and poses serious threats to public health as well as economic and social stability of many countries. Modeling and extrapolating in near real-time the evolution of COVID-19 epidemics is a scientific challenge, which requires a deep understanding of the factors undermining the dynamics of the …[Read More]
The 2020 extra-tropical monster cyclones and their (possible) relations with climate change
On February 9th, a British Airways Boeing 747 landed in London Heathrow airport just four hours and 56 minutes after its take-off in JFK, New York, setting the shortest flight-time for non-supersonic jets over this route. The jumbo jet took advantage of the fast upper-tropospheric winds associated with an exceptionally strong jet-stream which created tail …[Read More]
After Lorenzo and Ophelia, should we prepare European coasts for tropical storms and hurricanes?
Autumn is hurricane season in the north tropics and indeed 2019 does not make exception from this point of view. After Dorian hitting Bahamas and North Carolina, the American National Hurricane Center named Lorenzo a tropical depression originating near Capo Verde. On September 25th Lorenzo became a category 1 hurricane, according to the Saffir-Simpson scale. …[Read More]
NPG Paper of the Month: “Unravelling the spatial diversity of Indian precipitation teleconnections via a non-linear multi-scale approach”
Today’s we launch one of our promised activities: the NPG Paper of the Month. This month the award is achieved by Jürgen Kurths and co-authors for their paper “Unravelling the spatial diversity of Indian precipitation teleconnections via a non-linear multi-scale approach” (https://www.nonlin-processes-geophys.net/26/251/2019/). Ankit Agarwal, one of the authors of the manuscript, tells us about the …[Read More]
Abrupt Warming could bring our planet a “Hothouse Earth” with catastrophic consequences for our economy and society
Most of us have enjoyed swings in childhood. Some have even tried to swing faster and make a full 360 degrees’ loop. Those who succeeded had a very strange feeling of not being able to predict whether, increasing the energy of the swing, the transition from normal oscillations and 360 loops would happen. Indeed, there …[Read More]
Workshop report: Mathematics of the Economy and Climate
Just before the summer a group of about 40 scientists gathered in an old Monastery in the Netherlands (Kontakt der Kontinenten, Soesterberg) for a rather special collaborative workshop entitled “Mathematics of the economy and climate”. Mathematicians, climate scientists and economists – a group of scientists that normally does not mix and are rather unfamiliar with …[Read More]
