Turbulence Matters

By: Torsten Auerswald Most people are only consciously aware of the existence of turbulence when the pilot announces it. But apart from the discomfort of a bumpy flight, turbulence affects us in many other important aspects of daily life. The … Continue reading

The consequences of climate change: how bad could it get?

By: Nigel Arnell The United Nations Climate Action Summit held in New York on 23rd September was meant to be the occasion where countries and industry organisations made stronger commitments to reduce the emissions of the greenhouse gases that are … Continue reading

Probing the atmosphere with sound waves

By: Javier Amezcua Summer is a quiet time for both the University of Reading and the town itself. The buzzing that fills campus during term time is gone, the population decreases and activities are reduced. Some people find it relaxing … Continue reading

Do we have an appropriate description of energetic particles in the Earth’s outer radiation belt?

By: Oliver Allanson Figure 1: A particle undergoes Brownian motion. The short answer: probably not, at least not all of the time. In our state-of-the-art and physics-based numerical experiments, we analyse the motion of 100 million individual high-energy electrons that evolve … Continue reading

Climate change is spinning up the global energy and water cycles.

By: Richard Allan I was unfortunate enough to mildly injure my middle finger by typing too frenetically on a train journey from Toulouse returning from an Intergovernmental Panel on Climate Change meeting. I soon forgot about this by luckily stepping … Continue reading

Effect of the North Atlantic Ocean on the Northeast Asian climate: variability and predictability

By: Paul-Arthur Monerie North East Asia has warmed substantially after the mid-1990s leading to an increase in temperature extremes and to societal impacts (Dong et al., 2016). Predicting the variability of the North East Asian climate is therefore of primordial interest … Continue reading

It’s Hotter Than A Ginger Mill In Hades

By: Giles Harrison and Stephen Burt Or so they sometimes say in the south of the United States. But without a reference ginger mill or ready access to Hades, how do we know how hot it really is, and how … Continue reading

Why was there decadal increase in summer heat waves over China across the mid-1990s?

By: Buwen Dong Heat waves (HWs), commonly defined as prolonged periods of excessive hot weather, are a distinctive type of high-temperature extreme (Perkins 2015). These high-temperature extremes can lead to severe damage to human society and ecosystems. In our studies, … Continue reading

Making the best use of HPC

By: Grenville Lister High performance computing (HPC) is changing – there will be a new UK national service in early 2020 (and a period of time with no national service while the new platform is installed) – and the medium … Continue reading
