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

Climate change in the Mediterranean Sea

By Fanny Adloff The Mediterranean is the largest semi-enclosed sea on our planet. Acting as a miniature ocean, this basin is appropriate to study climate change impact on the ocean. The residence time of the Mediterranean waters – of about … Continue reading

Exploring the impact of the Atlantic Multidecadal Variability (AMV)

By Dan Hodson After 140 years of observations, we now know that the temperature of the surface of the Atlantic ocean slowly varied over time, cooling and warming over periods of decades (Figure 1). These slow variations in temperature sit … Continue reading

Recent progress on decadal prediction in the North Atlantic

by Jon Robson The North Atlantic is a region of the Earth that is characterised by pronounced multi-decadal variability in surface temperatures – a phenomenon that has become known as Atlantic Multi-decadal Variability (AMV, see Sutton et al for a … Continue reading

Can we use future data to improve our knowledge of the ocean?

By Chris Thomas An interesting problem in climate science is working out what happened in the world’s oceans in the last century. How did the temperature change, where were the currents strongest, and how much ice was there at the … Continue reading
