Tropical rainfall and sea surface temperature link could improve forecasts

By: Chris Holloway  and the University of Reading Press Office.  Tropical rainfall, averaged on seasonal time scales, is influenced far more strongly by nearby sea temperatures in the real world than in almost all climate simulations, scientists have found, paving … Continue reading

Deep Water Formation In The Mediterranean Sea

By: Giorgio Graffino “The Mediterranean Sea is a small-scale ocean”, as my old teacher used to tell me. All right, that was probably a bit exaggerated. Still, it’s true that the Mediterranean Sea provides an almost unique environment to study … Continue reading

Sea Surface Temperature Climate Data Record

By: Owen Embury Oceans cover over 70% of the Earth’s surface and knowing its temperature is crucial for understanding both weather and climate. Historically, sea surface temperatures (SSTs) have been measured in situ – from ships and automated buoys – … Continue reading

Building a predictive framework for studying causality in complex systems

By: Nachiketa Chakraborty I’m Nachiketa Chakraborty, a postdoctoral researcher working on the ERC project CUNDA (Causality under Non-linear Data Assimilation) led by Peter Jan van Leeuwen. My central goal is to come up with a Bayesian framework for studying causal … Continue reading

What sets the pattern of dynamic sea level change in the Southern Ocean?

By: Matthew Couldrey Figure 1a: Multi-model mean projection of dynamic and steric (i.e. due to thermal and/or haline expansion/contraction) sea level rise averaged over 2081-2100 relative to 1986-2005 forced with a moderate emissions scenario (RCP4.5), including 0.18 m +/- 0.05 … Continue reading

The Boundary Layer and Submesoscale Motions

By: Alan Grant Science is an exciting career, although what you may consider to be exciting will depend on your field. Sometimes things get most exciting when what initially appears to be a frustrating problem turns into an interesting problem. … Continue reading

Mechanisms of Climate Change in the Indian Summer Monsoon

By Jon Shonk Over one billion people are reliant on the rainfall of the Indian Summer Monsoon. During the wet season, which usually spans June to September, some parts of India receive over 90% of their total annual rainfall. Deficits … Continue reading

Clouds, climate and the Roaring 40s

By Richard Allan In our new research we have traced large and long-standing biases in computer simulations of climate, affecting the tempestuous Southern Ocean, to errors in cloud that emerge rapidly within the atmospheric models. Biases evolve over time through … Continue reading

Characteristics of cumulus population and microphysical properties observed over Southeast Atlantic

By Yann Blanchard Figure 1. Cumulus in the vicinity of Ascension Island, in a 100 x 100km image (which is close to global climate model spatial resolution) from MODIS onboard AQUA (22 July 2016) Shallow cumulus cover large areas in … Continue reading

Exploring the impact of Gulf Stream temperature biases on the global atmospheric circulation

By Robert Lee The climate state in numerical models often have differences when compared to a climatology from observations. These differences are often termed ‘biases’ and can be considered as a kind of error or deficiency in the model. These … Continue reading
