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]

NPG Paper of the Month: “On fluctuating momentum-exchange in idealised models of air-sea interaction”

Tommaso Alberti February 3, 2020

Probability density function of the energy (normalized so that the average is unity for each variable) lost by the atmosphere and gained by the ocean at t=300 and averaging time τ=0, atmosphere full-line, ocean dashed-line, and for averaging time τ=100, atmosphere dotted-line, ocean dashed-dotted-line. All are clearly non-Gaussian. (Source: A. Wirth, On fluctuating momentum exchange in idealised models of air–sea interaction, Nonlin.

This month the NPG Paper of the Month award is achieved by Achim Wirth for his paper “On fluctuating momentum-exchange in idealised models of air-sea interaction” (https://www.nonlin-processes-geophys.net/26/457/2019/). Achim tells us about the importance of the results achieved with this paper for investigating the energy coupling between the ocean and the atmosphere. Achim obtained his PhD at th ...[Read More]
