The current COVID-19 situation has profoundly changed our daily lifes and has also affected our way to perform and share research. In today’s world a lot of efforts have been made to minimize the impact of working from home and exchange thoughts with colleagues, and also the usual annual General Assembly of the European Geosciences Union (EGU) has been moved online. Thus, the largest online ...[Read More]

NPG Paper of the Month: “Application of a local attractor dimension to reduced space strongly coupled data assimilation for chaotic multiscale systems”
Local dynamical properties of a segment of an example run for
the coupled Lorenz system. (a) Alignment of directions of error growth plotted along the x coordinate of the ocean subsystem. Large orange stars indicate high alignment of error growth in the unstable or neutral subspaces. (b) Finite-time Lyapunov exponents (FTLEs) computed over window τ = 4. (c) Local Kaplan-Yorke dimension calculated from FTLEs. (Source: Quinn, O’Kane, and Kitsios, Application of

Dr. Courtney obtained her PhD in Mathematics at the University of Exeter (UK) researching critical transitions in dynamical syst ...[Read More]
How Climate Sciences can help in understanding uncertainties in Covid-19 epidemic projections
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]
