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 a small change in initial conditions leads to vastly ...[Read More]

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

September 20, 2019
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 ...[Read More]

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 Methods in a concise, efficient, and complete way. Writin ...[Read More]

Stromboli: The Lighthouse of the Mediterranean

In the last months two paroxysmal explosive eruptions took place at Stromboli volcano: the first one, totally unexpected, on 3rd July (Video 1) that sadly cost the life of a person and the second and, currently, last one about three weeks ago, on the 28th August (Video 2). Today we try to answer a couple of questions about Stromboli and its eruptions. Are these paroxysmal eruptions common or rare ...[Read More]

#mineralmonday: your weekly* dose of obscure mineralogy, every Monday** [*not guaranteed; **or possibly Tuesday-Sunday] What is it? Tiptopite: K2Na1.5Ca0.5Li3Be6(PO4)6(OH)2•(H2O) What’s it made of?  Take a deep breath and recite after me: potassium, sodium, calcium, lithium, beryllium, phosphorus, oxygen and water (H2O). Is it pretty? Yes, it’s a beautiful fibrous mineral. You wouldn&# ...[Read More]

Climate Change & Cryosphere – Why is the Arctic sea-ice cover retreating?

The Arctic Ocean surface is darkening as its sea-ice cover is shrinking. The exact processes driving the ongoing sea-ice loss are far from being totally understood. In this post, we will investigate the different causes of the recent retreat of the Arctic sea-ice cover, using the most updated literature… Arctic sea ice is disappearing Due to its geographical position centered around the Nort ...[Read More]

A brighter future for the Arctic

This is a follow-up from a previous publication. Recently, a new analysis of the impact of Black Carbon in the Arctic was conducted within a European Union Action. “Difficulty in evaluating, or even discerning, a particular landscape is related to the distance a culture has traveled from its own ancestral landscape. As temperate-zone people, we have long been ill-disposed toward deserts and ...[Read More]

YHS interview Martyn P. Clark: “rainfall-runoff modelling, per se, is dead”

September 11, 2019

In its “Hallway Conversations” series, the Young Hydrologic Society has recently published an interview with Martyn P. Clark, who is currently professor and the Associate Director of Centre for Hydrology and Canmore Coldwater Lab, at the University of Saskatchewan, Canada. The interview was conducted by Sina Khatami, a PhD student at the University of Melbourne. With their agreement, we reproduce ...[Read More]
