What Is The World Climate Research Programme And Why Do We Need It?

Posted on 18 July, 2022 by danaallen

By: Rowan Sutton My schedule last week was rather awry.  Over four days I took part in a meeting of 50 or so climate scientists from around the world.  Because of the need to span multiple time zones, the session … Continue reading →

Density Surfaces In The Oceans

Posted on 4 July, 2022 by danaallen

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?

Posted on 27 June, 2022 by danaallen

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.

Posted on 20 June, 2022 by danaallen

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

Posted on 13 June, 2022 by danaallen

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 →

Co-Producing New Sub-Seasonal Weather Forecasts in Africa

Posted on 23 May, 2022 by danaallen

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?

Posted on 16 May, 2022 by danaallen

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

Posted on 9 May, 2022 by danaallen

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?

Posted on 2 May, 2022 by danaallen

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 →
