  • Anisotropic small-scale constraints on energy in rotating stratified turbulence 

    Kurien, Susan; Wingate, Beth; Taylor, Mark (European Physical Society, 2008-10)
    Rapidly rotating, stably stratified three-dimensional inviscid flows conserve both energy and potential enstrophy. We show that in such flows, the forward cascade of potential enstrophy imposes anisotropic constraints on ...

    In many areas of animal behaviour research, improvements in our ability to collect large and detailed data sets are outstripping our ability to analyse them. These diverse, complex and often high-dimensional data sets ...
  • Approximate Bayesian Computation and simulation-based inference for complex stochastic epidemic models

    Approximate Bayesian Computation (ABC) and other simulation-based inference methods are becoming increasingly used for inference in complex systems, due to their relative ease-of-implementation. We briefly review some of ...
  • AppTCP: The design and evaluation of application-based TCP for e-VLBI in fast long distance networks 

    Wang, G; Wu, Y; Dou, K; Ren, Y; Li, J (Elsevier, 2014-10)
    Electric Very Long Baseline Interferometry (e-VLBI) is a typical astronomical interferometry used in radio astronomy. It allows observations of an object that are made simultaneously by many radio telescopes to be combined, ...
  • Arctic amplification decreases temperature variance in Northern mid- to high-latitudes 

    Screen, James A. (Nature Publishing Group, 2014)
    Changes in climate variability are arguably more important for society and ecosystems than changes in mean climate, especially if they translate into altered extremes [1, 2, 3]. There is a common perception and growing ...
  • The Arctic Predictability and Prediction on Seasonal-to-Interannual TimEscales (APPOSITE) data set version 1

  • Are changes in global precipitation constrained by the tropospheric energy budget? 

    Lambert, F. Hugo; Allen, Myles R. (American Meteorological Society, 2009)
    A tropospheric energy budget argument is used to analyze twentieth-century precipitation changes. It is found that global and ocean-mean general circulation model (GCM) precipitation changes can be understood as being due ...
  • Are large submarine landslides temporally random or do uncertainties in available age constraints make it impossible to tell? 

    Pope, EL; Talling, PJ; Urlaub, M; Hunt, JE; Clare, MA; Challenor, Peter G. (Elsevier, 2015-07-29)
    © 2015. Large (>1km3) submarine landslides can potentially generate very destructive tsunamis and damage expensive sea floor infrastructure. It is therefore important to understand their frequency and triggers, and whether ...
