Beyond Tectonics: Can only tectonically active planets sustain life?

Beyond Tectonics: Can only tectonically active planets sustain life?

This edition of “Beyond Tectonics” is brought to you by David Waltham. David is a professor of Geophysics at Royal Holloway who studies Geology, Astronomy and Astrobiology. His current research focus is on whether the Earth is “special” because it is habitable, or if the Earth is one of a vast amount of life-bearing planets. …[Read More]

Imaggeo on Mondays: The polje between sky and Earth

Poljes are one of the most impressive features existing in karst landscapes. These large flat closed depressions are prone to regular flooding that can form temporary lakes on their surface. Planinsko Polje [in Slovenia] is surely the most famous example of polje existing. The highest floods can reach up to 8 metres above the gauging …[Read More]

Climate Change & Cryosphere – Summer 2019: The year that the Arctic was sunburned

Climate Change & Cryosphere – Summer 2019: The year that the Arctic was sunburned

June, July and August 2019 saw extensive heat waves across Europe, with air temperatures reaching above 40°C in many countries. In response, record breaking ice melt was observed in Greenland and wildfires in Siberia, Alaska, Arctic Canada and Greenland occurred. A particularly dry and warm summer was responsible for hemisphere-wide changes to the cryosphere. In …[Read More]

A simple model of convection to study the atmospheric surface layer

A simple model of convection to study the atmospheric surface layer

Since being immortalised in Hollywood film, “the butterfly effect” has become a commonplace concept, despite its obscure origins. Its name derives from an object known as the Lorenz attractor, which has the form of a pair of butterfly wings (Fig. 1). It is a portrait of chaos, the underlying principle hindering long-term weather prediction: just …[Read More]

NPG Paper of the Month: “Unravelling the spatial diversity of Indian precipitation teleconnections via a non-linear multi-scale approach”

Schematic map of spatial diversity of Indian precipitation teleconnections at different time scales. (a) ENSO, (b) IOD, (c) NAO, (d PDO, and (e) AMO. Colors are consistent with the Indian community shown in the right figure. Presence of color in community segment indicates significant synchronization between teleconnection and Indian precipitation. Every single segment of circle shows the temporal scale. Cardinal direction has been projected in the background of each circle.

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]

Writing the Methods Section

Writing the Methods Section

An important part of science is to share your results in the form of papers. Perhaps, even more important is to make those results understandable and reproducible in the Methods section. This week, Adina E. Pusok, Postdoctoral Researcher at the Department of Earth Sciences, University of Oxford, shares some very helpful tips for writing the …[Read More]
