About the revolution of generating butterflies Imagine the most vibrant butterfly you can conceive. Congratulations – you’ve just achieved what generative AI does! This technology can create images from simple text descriptions, revolutionising image generation. But as geoscientists, how can we use it to improve the prediction of chaotic system like our weather? How can it help us to discover prop ...[Read More]

Persistent atmospheric circulation patterns are not a necessary requirement for warm temperature extremes in Europe. This key finding from a recent study led by Emma Holmberg challenges a more traditional meteorological view of persistence, which typically considers summertime heatwaves, especially in northern regions of Europe, to be synonymous with persistent atmospheric flow patterns. Furthermo ...[Read More]

Socio-economic and security implications of global heating

Socio-economic and security implications of global heating
Temperature anomaly for July 2022 with respect to reference period 1959-1989. Data: 2m temperatures from ERA5.

This year, like in the last few years, we are experiencing the effects of global heating in increasingly personal ways. The summer of 2022 exposed us to ever more extreme heat waves in North America, Europe, and Asia. For instance, the heat wave in India and Pakistan reached temperatures of 49C in Nawabshah, Pakistan. North America too experienced devastating heat waves and wildfires. Los Angeles ...[Read More]

Extratropical cyclones play a key role in modulating the precipitation and wind in mid-latitudes and can be responsible for extreme wet and windy events. With global warming, the dynamics and thermodynamics associated with these atmospheric systems are being affected. However, due to the complexity of modelling the climate system, a challenge arises when evaluating the influence that climate chang ...[Read More]
