Abstract. Accurately representing coastal and shelf seas in global ocean models represents one of the grand challenges Earth system science. They are regions immense societal importance through goods services they provide, hazards pose their role global-scale processes cycles, e.g. carbon fluxes dense water formation. However, poorly represented current generation models. In this contribution, we aim to briefly characterise problem, then identify important physical processes, scales, needed...
Shelf and coastal seas are regions of exceptionally high biological productivity, rates biogeochemical cycling immense socio-economic importance. They are, however, poorly represented by the present generation Earth system models, both in terms resolution process representation. Hence, these models cannot be used to elucidate role ocean global cycles effects change (both direct anthropogenic climatic) having on them. Here, we a for simulating all around world (the Global Coastal Ocean...
Air quality (AQ) significantly impacts human health, influenced by both natural phenomena and activities. In 2021, heightened awareness of AQ's health prompted the revision World Health Organization (WHO) guidelines, advocating for stricter pollution standards. However, research on AQ has predominantly focused high-income countries densely populated cities, neglecting low- middle-income countries, particularly Pacific Island Countries, Territories, States (PICTS). This systematic review...
Abstract This paper outlines an approach to complex spatio-temporal marine ecosystem modelling as applied the North Western European Continental Shelf. The model presented here goes further than previous work, we combine a higher resolution hydrodynamic model, POL-3DB baroclinic with Regional Seas Ecosystem Model. combination of models includes many processes (benthic-pelagic coupling, dynamic zooplankton and nitrogen, phosphorous silicate cycling) authors have identitied missing from their...
The Proudman Oceanographic Laboratory Coastal Ocean Modelling System and the European Regional Seas Ecosystem Model are applied at eddy‐resolving (∼1.8 km) scales to stratified region of western Irish Sea investigate effects advective transport processes on ecosystem. We find currents can nutrient‐rich water into otherwise nutrient‐depleted surface layer region, fueling intermittent production throughout summer. involved fall three classes: large‐scale wind density‐driven circulation,...
The seismic potential of southern China is associated with the collision between Indian and Eurasian plates.This manifested in western Sichuan Plateau by several seismically active systems faults, such as Longmen Shan.The seismicity observed on Shan fault includes recent events magnitudes up to 6.5, one 12 May 2008 M w 7.9 Wenchuan earthquake.Herewith, part an ongoing research program, a recently optimized threedimensional (3D) wave propagation parallel finite-difference code was used obtain...
On 3 June 1932, an M s 8.2 shallow thrust subduction earthquake struck the Colima–Jalisco (CJ) region of Mexico at epicentral distance ∼250 km from Guadalajara, second largest town in Mexico. The return period these CJ earthquakes has been estimated 77 to 126 years, which suggests next is likely occur between 2009 and 2058. As a step toward estimating seismic hazard posed by potential s 8.2+ events on we present study consisting following: (1) the analysis strong ground motions recorded...
Summary form only given. Advances in computational science are closely tied to developments high-performance computing. We consider the case of shelf sea modelling where models have been growing complexity and model domains grid resolutions shrinking pace with increasing storage capacity computing power high-end systems. Terascale systems now readily available performance levels measurable TeraFlop/s memories counted TeraBytes). The scientific is being made for regional at 1 km resolution,...
Abstract. We present an approach which we call PSyKAl that is designed to achieve portable performance for parallel finite-difference, finite-volume, and finite-element earth-system models. In the code related underlying science formally separated from parallelization single-core optimizations. This separation of concerns allows scientists their independently hardware architecture optimization specialists be able tailor a particular machine, code. have taken free-surface part NEMO ocean...
Summary Ongoing transistor scaling and the growing complexity of embedded system designs has led to rise MPSoCs (Multi‐Processor System‐on‐Chip), combining multiple hard‐core CPUs accelerators (FPGA, GPU) on same physical die. These devices are great interest supercomputing community, who increasingly reliant heterogeneity achieve power performance goals in these closing stages race exascale. In this paper, we present a network interface architecture networking infrastructure, designed sit...
In recent years, there has been renewed interest in the use of field-programmable gate arrays (FPGAs) for high-performance computing (HPC). this paper, we explore techniques required by traditional HPC programmers porting applications to FPGAs, using as an example LFRic weather and climate model. We report on first steps FPGAs EuroExa architecture. have used Vivado High-Level Syntheusywwi implement a matrix-vector kernel from code Xilinx UltraScale+ development board containing XCZU9EG...

Abstract We introduce HPCx—the U.K.'s new National HPC Service—which aims to deliver a world‐class service for capability computing the U.K. scientific community. HPCx is targeting an environment that will both result in world‐leading science and address challenges involved scaling existing codes levels required. Close working relationships with consortia user groups throughout research process be central feature of service. A significant number key applications have already been ported...
The establishment of the UK Applied Aerodynamics Consortium in 2004 brought together many UK’s leading research groups to tackle challenging aerodynamic problems on national computing facility, HPCx.
