How Climate Sciences can help in understanding uncertainties in Covid-19 epidemic projections

Davide Faranda March 31, 2020

Artistic view of the Covid-19 virus moving along an increasing trend.

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 epidemics. Despite the importance of havin ...[Read More]

Today’s NP Interviews hosts the Lewis Fry Richardson Medallist Shaun Lovejoy. Shaun has degrees in physics from Cambridge and McGill University; he has been a McGill professor since 1985. For four decades, he has developed fractal, scaling ideas in the geosciences, contributing to advances in cascade processes, multifractals, anisotropic scale invariance, space-time multifractal modeling as well a ...[Read More]

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

Tommaso Alberti 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. (Source: J.

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]
