Is climate change making the weather more extreme?

Is climate change making the weather more extreme?

Denver, Sept. 06: it is midday and Jonathan and Maria are sunbathing at City Park. They feel uncomfortable as the temperature has already reached 36°C. While they decide to go back home, their favoured weather app displays an unbelievable snowstorm watch for Tuesday Sept. 08. The forecast turns out to be rather accurate as all …[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]
