Importance of Longwave Radiative Forcing by Icy Clouds in Maintaining Miocene High‐Latitude Warmth Open
During the early‐to‐middle Miocene, global mean surface temperature (GMST) was approximately 8°C warmer than preindustrial, with a greater temperature increase in polar regions than the tropics. However, existing Miocene simulations undere…
Identifying the drivers of flood generation mechanisms and their seasonal variabilities.  Open
Extreme rainfalls and floods have caused severe socio-economic and environmental losses in most parts of the world and are predicted to exacerbate due to the changing climate. Highly saturated soil, extreme rainfall, and heavy snowmelt are…
Putting the English Flooding of 2019–2021 in the Context of Antecedent Conditions Open
England experienced a sequence of extreme flood events between June 2019 and April 2021. To understand the severity and likelihood of the events, a set of over 300 flow and river level stations was investigated for key events (identified b…
Widespread flooding dynamics under climate change: characterising floods using grid-based hydrological modelling and regional climate projections Open
An event-based approach has been used to explore the potential effects of climate change on the spatial and temporal coherence of widespread flood events in Great Britain. Time series of daily mean river flow were generated using a gridded…
Global trend and drought analysis of near-natural river flows: The ROBIN Initiative Open
With hydrological extremes becoming more frequent and intense in a changing world, the impact on livelihoods, infrastructure, and economies is crucial. River flow data is a valuable resource and can be used to understand and analyse trends…
A global dataset of near-natural basins for climate change detection Open
As hydrological extremes become more severe in the warming world, impacts to livelihoods, infrastructure, and economies worsen. To attribute emerging trends to climate change, we need to remove the signal of anthropogenic activities, such …
Understanding and disentangling of flood generation mechanisms Open
Extreme rainfalls and floods have caused severe socio-economic and environmental losses in most parts of the world and are predicted to exacerbate due to the changing climate. Highly saturated soil, extreme rainfall, and heavy snowmelt are…
Beyond the local climate change uplift – The importance of changes in spatial structure on future fluvial flood risk in Great Britain Open
Widespread spatially coherent flood events can cause severe damage and disruption. Climate change has the potential to change the severity and frequency of such events. Despite this, assessment of future fluvial flood risk typically gives …
Beyond the local climate change uplift – The importance of changes in spatial structure on future fluvial flood risk in Great Britain Open
Widespread, spatially coherent flood events can cause severe damage and disruption. Climate change has the potential to change the severity and frequency of such events. Despite this, climate change risk assessments of future fluvial flood…

Spatially coherent statistical simulation of widespread flooding events under climate change Open
Simulating rare widespread hydrological events can be difficult even with the use of modelled data such as the UKCP18 12 km regional climate projections. To generate larger event sets for application in catastrophe modelling, two statistic…
ROBIN - A Reference Observatory of Basins for INternational hydrological climate change detection Open
Future climate projections suggest hydrological extremes (floods and droughts) will become more frequent and severe, further heightening the already substantial impacts they cause to lives and livelihoods, infrastructure and economies. To …
Flood Frequency Estimation in Data-Sparse Wainganga Basin, India, Using Continuous Simulation Open
Monsoon-related extreme flood events are experienced regularly across India, bringing costly damage, disruption and death to local communities. This study provides a route towards estimating the likely magnitude of extreme floods (e.g., th…
Widespread flooding dynamics changing under climate change: characterising floods using UKCP18 Open
An event-based approach has been used to explore the potential effects of climate change on the spatial and temporal coherence of widespread flood events in Great Britain. Time series of daily mean river flow were generated using a gridded…
Energy Spectrum of Two-Dimensional Acoustic Turbulence Open
We report an exact unique constant-flux power-law analytical solution of the wave kinetic equation for the turbulent energy spectrum, E(k)=C_{1}sqrt[ϵac_{s}]/k, of acoustic waves in 2D with almost linear dispersion law, ω_{k}=c_{s}k[1+(ak)…
ROBIN - A Reference Observatory of Basins for INternational hydrological climate change detection   Open
Floods and droughts may become more severe in a warming world, potentially furthering the significant adverse impacts they cause to lives and livelihoods, infrastructure, and economies. To adapt to future changes in water quantity and regi…
Climate change allowances, non‐stationarity and flood frequency analyses Open
When considering future adaptation to climate change in UK fluvial flood alleviation schemes, the current recommendation by the Environment Agency (England) is to increase peak design flood flows by a preselected percentage. This allowance…
Simulating spatially coherent widespread flood events for risk modelling in the UK Open
Within risk modelling, event footprints are used to demonstrate how an extreme event impacts different locations at a similar time. Currently, estimates of future impacts from extreme events are derived by applying climate change allowance…
An epidemic model for an evolving pathogen with strain-dependent immunity Open
Between pandemics, the influenza virus exhibits periods of incremental evolution via a process known as antigenic drift. This process gives rise to a sequence of strains of the pathogen that are continuously replaced by newer strains, prev…

Have trends changed over time? A study of UK peak flow data and sensitivity to observation period Open
Classical statistical methods for flood frequency estimation assume stationarity in the gauged data. However, recent focus on climate change and, within UK hydrology, severe floods in 2009 and 2015 has raised the profile of statistical ana…
Revising the BFIHOST catchment descriptor to improve UK flood frequency estimates Open
The estimate of the base flow index (BFI) based on the Hydrology of Soil Types (HOST) classification, BFIHOST, provides a measure of catchment responsiveness. BFIHOST is used with other variables to estimate the median annual maximum flood…
