Density Surfaces In The Oceans

By: Remi Tailleux Below the mixed layer, shielded from direct interaction with the atmosphere, ocean fluid parcels are only slowly modified by turbulent mixing processes and become strongly constrained to move along density surfaces of some kind, called `isopycnal’ surfaces. … Continue reading

Is Europe At Risk From Hurricanes?

By: Reinhard Schiemann Growing up in Europe late last century, I would have been a little surprised at this question, and my knee-jerk answer would have been a firm no: hurricanes happened on TV in far-away tropical places, bending and … Continue reading

Forecasting Rapid Intensification In Hurricanes And Typhoons.

By: Peter Jan Leeuwen We all know the devastating power of hurricanes, typhoons, and their Southern Hemisphere counterparts. It is crucial that we predict their behaviour accurately to avoid loss of life and to better guide large-scale infrastructure operations. Although … Continue reading

A Different Kind Of Turbulence

By Miguel Teixeira It might be thought that turbulence is essentially the same everywhere. However, its mixing efficiency depends not only on its intensity (as might be expected intuitively), but also on more subtle properties, such as its anisotropy (which … Continue reading

What are the challenges in forecasting the impacts of tropical cyclones?

By: Liz Stephens Last year I joined the Meteorology department in a joint-post between the University of Reading and the Red Cross Red Crescent Climate Centre (RCCC), but I still suspect most people have no idea exactly what it is … Continue reading

Co-Producing New Sub-Seasonal Weather Forecasts in Africa

By: Linda Hirons Weather-related extremes affect the lives and livelihoods of millions of people across tropical Africa. Access to reliable, actionable weather information is key to improving the resilience of African populations and economies. Specifically, at the extended sub-seasonal timescale … Continue reading

Are There Climate Consequences of Using Hydrogen as a Replacement for Coal, Gas and Oil?

By: Keith Shine There are many possible avenues to reduce carbon dioxide emissions. One of these is a shift to using hydrogen (H2) as a fuel source; it could potentially be used for many current CO2-emitting activities, including industry, heating … Continue reading

Fieldwork Without The Footprint

By: Joy Singarayer Over the past two years, we have all faced challenges to our working patterns due to the Covid-19 pandemic. Researchers undertaking overseas fieldwork have found many ways to redefine, reschedule, and adapt their approaches in light of … Continue reading

Has The Atlantic Ocean Circulation Been In Long-term Decline?

By: Jon Robson A number of recent high-profile studies have strongly suggested that an important part of the North Atlantic Ocean circulation – the AMOC – has declined and that it is edging closer to a tipping point. Such a … Continue reading

Antarctic Sea Ice: The Global Climate Driver Of The South

By: Holly Ayres In the Northern Hemisphere, our closest region of sea ice (not to be confused with land ice) is the Arctic, a vast region of frozen ocean at the North Pole. Antarctica, a huge mountainous land mass at … Continue reading
