The UK Met Office global circulation model with a sophisticated radiation scheme applied to the hot Jupiter HD 209458b

Publication ID: pub.1056925754

Publication date: 26/10/2016

Keywords: Atmospheres; Gaseous Planets; HD 209458b; Hydrodynamics; Numerical; Planets; Radiative Transfer; Satellites

To study the complexity of hot Jupiter atmospheres revealed by observations of increasing quality, we have adapted the UK Met Office Global Circulation Model (GCM), the Unified Model (UM), to these exoplanets. The UM solves the full 3D Navier-Stokes equations with a height-varying gravity, avoiding the simplifications used in most GCMs currently applied to exoplanets. […]

Fluvial sediment supply to a mega-delta reduced by shifting tropical-cyclone activity

Publication ID: pub.1051437103

Publication date: 19/10/2016

Keywords: Asia, Southeastern; Cambodia; Climate Change; Cyclonic Storms; Geologic Sediments; History, 20th Century; History, 21st Century; Hydrology; Kratie; Laos; Luang Prabang; Mekong River; Mukdahan; Pakse; Rain; Rivers; Stung Treng; Thailand; Tropical Climate

About a third of the sediment delivery of the Mekong River is shown to be associated with rainfall generated by tropical cyclones, suggesting that future delta stability will be strongly moderated by changes to tropical cyclone intensity, frequency and track.

Skilful predictions of the winter North Atlantic Oscillation one year ahead

Publication ID: pub.1032702241

Publication date: 17/10/2016

Keywords: Atmospheric Variability; Climate Variability; Effects of Solar Forcing; Ensemble Size; Europe; Global; Latest Generation Seasonal Forecasting Systems; Model Biases; North America; North Atlantic Region; Skilful Dynamical Model Predictions; Tropical Pacific Region; Winter North Atlantic Oscillation

The North Atlantic Oscillation profoundly influences European and North American winter weather. Dynamical model predictions now exhibit skill in prediction of the winter North Atlantic Oscillation more than one year in advance.

The effects of consistent chemical kinetics calculations on the pressure-temperature profiles and emission spectra of hot Jupiters

Publication ID: pub.1056925513

Publication date: 13/10/2016

Keywords: Atmospheres; Composition; Hot Jupiter Exoplanets; Planets; Satellites

In this work we investigate the impact of calculating non-equilibrium chemical abundances consistently with the temperature structure for the atmospheres of highly-irradiated, close-in gas giant exoplanets. Chemical kinetics models have been widely used in the literature to investigate the chemical compositions of hot Jupiter atmospheres which are expected to be driven away from chemical equilibrium […]

Transitions in coral reef accretion rates linked to intrinsic ecological shifts on turbid-zone nearshore reefs

Publication ID: pub.1013719579

Publication date: 07/10/2016

Keywords: Australasia; Australia; Biogenic Structures; Carbonic Rocks; Cenozoic; Coral Sea; Cores; Ecology; Ecosystems; Geomorphology; Great Barrier Reef; Halifax Bay; Holocene; Marine Environment; Nearshore Environment; Pacific Ocean; Pleistocene; Quaternary; Queensland Australia; Reef Builders; Reefs; Sedimentary Rocks; Sedimentary Structures; South Pacific; Southwest Pacific; Turbidity; West Pacific

Nearshore coral communities within turbid settings are typically perceived to have limited reef-building capacity. However, several recent studies have reported reef growth over millennial time scales within such environments and have hypothesized that depth-variable community assemblages may act as equally important controls on reef growth as they do in clear-water settings. Here, we explicitly test […]

Global resilience analysis of water distribution systems

Publication ID: pub.1041576915

Publication date: 04/10/2016

Keywords: Forecasting; Global; Models, Theoretical; Water; Water Supply

Evaluating and enhancing resilience in water infrastructure is a crucial step towards more sustainable urban water management. As a prerequisite to enhancing resilience, a detailed understanding is required of the inherent resilience of the underlying system. Differing from traditional risk analysis, here we propose a global resilience analysis (GRA) approach that shifts the objective from […]
