The 2020 extra-tropical monster cyclones and their (possible) relations with climate change

The 2020 extra-tropical monster cyclones and their (possible) relations with climate change

On February 9th, a British Airways Boeing 747 landed in London Heathrow airport just four hours and 56 minutes after its take-off in JFK, New York, setting the shortest flight-time for non-supersonic jets over this route. The jumbo jet took advantage of the fast upper-tropospheric winds associated with an exceptionally strong jet-stream which created tail winds of about 400km/h. Over the United Ki ...[Read More]

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

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

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]

Why Bushfires raged out of control across Australia?

Why Bushfires raged out of control across Australia?

Australian wildfires have burned an impressively large surface and caused the death of at least 24 citizens as well as of numerous animals. This immense disaster raises questions about its linkage with climate change, the possibility of controlling these events and the future of Australian wildlife ecosystems. While the first question will be addressed by soon to come attribution studies, and the ...[Read More]

Medicanes, thunderstorms and Acqua Alta in Venice: what is the role of climate change?

Medicanes, thunderstorms and Acqua Alta in Venice: what is the role of climate change?

A Mediterranean cyclone, high tides and climate change: these three ingredients made the 12/11/2019 acqua alta event in Venice exceptional. This combination of causes determined what climate scientists define as a compound extreme event, a non-linear mix of factors which led to several and connected extreme weather phenomena in the Mediterranean area. Let us start by the analysis of the atmospheri ...[Read More]
