  • Transition of El Niño to La Niña can be driven by regional perturbations a year ahead

    Open AccessChris Kent, Adam A Scaife et al.ARTICLEEnvironmental Research Letters2025

    Interannual forecasts provide skilful predictions of El Niño-Southern oscillation (ENSO) up to a year in advance, however our understanding of what drives the ensemble skill and diversity of outcomes across members is limited. Using a fully coupled ocean–atmosphere ensemble forecasting system, we investigate the causality of regional perturbations on the evolution of ENSO at interannual timescales. Using forecasts initialised on 1 November 2009, …

  • Surface hazards in North-west Europe following sudden stratospheric warming events

    Open AccessRichard J Hall, Dann Mitchell et al.ARTICLEEnvironmental Research Letters2023

    Sudden stratospheric warmings (SSWs) have been linked to surface temperature anomalies, but how these connect to changes in the likelihood of specific weather extremes and their associated weather patterns remains uncertain. While, on average, it is true that cold surface temperatures follow SSW events, particularly in Northern Europe, there is considerable event-to-event variability. Over the British Isles and Central Europe, only around 45% of …

  • Predicting future UK nighttime urban heat islands using observed short-term variability and regional climate projections

    Open AccessCharlotte Doger de Speville, William J M Seviour et al.ARTICLEEnvironmental Research Letters2023

    By 2050, 68% of the world’s population and 90% of the UK’s population are estimated to be living in urban areas. It is widely acknowledged that urban areas tend to be warmer than rural areas (the urban heat island (UHI) effect), and that increased summer temperatures increase morbidity and mortality. It is therefore important to know how the UHI intensity will change in the future. Recent work has used observed daily UHI-temperature relationships…

  • The vertical profile of recent tropical temperature trends: Persistent model biases in the context of internal variability

    Open AccessDann Mitchell, Dann M Mitchell et al.ARTICLEEnvironmental Research Letters2020

    Tropospheric and stratospheric tropical temperature trends in recent decades have been notoriously hard to simulate using climate models, particularly in the upper troposphere. Aside from the warming trend itself, this has broader implications, e.g. atmospheric circulation trends depend on latitudinal temperature gradients. In this study, tropical temperature trends in the CMIP6 models are examined, from 1979 to 2014, and contrasted with trends f…
