Adapting to life: ocean biogeochemical modelling and adaptive remeshing

We present a novel method of simulating ocean biogeochemical behaviour on a vertically adaptive computational mesh, where the mesh changes in response to the biogeochemical and physical state of the system throughout the simulation.

A general framework for understanding the response of the water cycle to global warming over land and ocean

In an attempt to develop a simple framework for local-scale analysis we found that the climate model output shows a remarkably close relation to the long-standing Budyko framework of catchment hydrology.

Modelling environmental influences on calving at Helheim Glacier in eastern Greenland

Calving is an important mass-loss process for many glaciers worldwide, and has been assumed to respond to a variety of environmental influences. We present a grounded, flowline tidewater glacier model using a physically-based calving mechanism, applied to Helheim Glacier, eastern Greenland.

Effects of stratospheric ozone recovery on photochemistry and ozone air quality in the troposphere

In this study, the authors examine the implications of stratospheric ozone recovery for the tropospheric chemistry and ozone air quality with a global chemical transport model (GEOS-Chem).

Little Ice Age climate reconstruction from ensemble reanalysis of Alpine glacier fluctuations

Here the author analyses terminus position histories from an ensemble of seven glaciers in the Alps with a macroscopic model of glacier dynamics to derive a history of glacier equilibrium line altitude for the time span 400–2010 C.E.

Earthquake-induced ground failures in Italy from a reviewed database

10 April 2014

A database of earthquake-induced ground failures in Italy is presented, and the related content is analysed. The catalogue collects data regarding landslides, liquefaction, ground cracks, surface faulting and ground changes triggered by earthquakes of Mercalli epicentral intensity 8 or greater that occurred in the last millennium in Italy.

Fracture-induced softening for large-scale ice dynamics

To account for the macroscopic effect of fracture processes on large-scale viscous ice dynamics (i.e., ice-shelf scale), the authors apply a continuum representation of fractures and related fracture growth into the prognostic Parallel Ice Sheet Model and compare the results to observations.

Regional and inter-regional effects in evolving climate networks

In this study we identify the sources of the evolving network characteristics by considering a reduced-dimensionality description of the climate system using network nodes given by rotated principal component analysis. The time evolution of structures in local intra-component networks is studied and compared to evolving inter-component connectivity.

Modelling global-scale climate impacts of the late Miocene Messinian Salinity Crisis

By running extreme, sensitivity-type experiments with a fully coupled ocean–atmosphere general circulation model, this paper investigates the potential of various Messinian Salinity Crisis Mediterranean Outflow Water scenarios to impact global-scale climate.

Further evidence of important environmental information content in red-to-green ratios as depicted in paintings by great masters

In this paper, the authors examine sunsets painted by famous artists as proxy information for the aerosol optical depth after major volcanic eruptions.
