Investigation of future climate change over the British Isles using weather patterns

Climate Dynamics, Journal Year: 2021, Volume and Issue: 58(9-10), P. 2405 - 2419

Abstract For those involved in planning for regional and local scale changes future climate, there is a requirement climate information to be available context more usually associated with meteorological timescales. Here we combine tool used numerical weather prediction, the 30 patterns produced by Met Office, which are already applied operationally prediction models, assess UK Climate Projections (UKCP) Global ensemble. Through assessing projected frequency of at end 21st Century, determine that large-scale circulation tend towards an increase winter cyclonic westerly wind conditions expense anticyclonic, settled/blocked patterns. In summer, results indicate shift dry settled types corresponding reduction wet windy types. Climatologically this suggests warmer, wetter winters drier summers; consistent headline findings from 2018. This paper represents first evaluation analysis within UKCP Global. It provides detailed assessment these through Century how uncertainty emissions, structural perturbed parameters affects results. We show use tandem projections useful work investigating range weather-related features such as extreme precipitation.

Optimizing photovoltaic electric generation and roof insulation in existing residential buildings

Energy and Buildings, Journal Year: 2021, Volume and Issue: 255, P. 111652 - 111652

Refurbishing existing buildings to reduce energy use is a priority worldwide greenhouse gas emissions. Millions of around the globe have old roofs that are poorly insulated, but with large roof surface areas could potentially provide significant renewable generation. Often, photovoltaic panels simply added onto regardless thermal integrity. However, due weathering, frequently need repairs over their useful life. We evaluate comprehensive methodology using EnergyPlus and TRNSYS simulation tools how best combine solar electric generation improved insulation achieve cost reductions, improve efficiency utilization at time accessed. Advantages combining efforts into single intervention has not been fully explored in building research. further incorporate important impacts PV stand-off arrays on performance from shading long-wave irradiance skies. These influences comfort implications for insulated structures increasing summer heat waves associated climate-related warming. They also strong interaction installed levels. With an example analysis Milan, Italy, we considered three typical residential types wide-use world (single-family, multi-family, apartment complex) different geometries, levels constructions. evaluated two options: re-roofing (roof repair/replacement) refurbishment (energy improvement). optimized via state-of-the-art simulations considering both documented costs. was quantified detail, exploring array affects performance, influence previously considered. This particularly uninsulated where upper floors can experience excessive summertime heating. Both heating cooling needs determine optimal what savings- related costs- be obtained depending differing parameters. found appropriate cost-effective option net primary buildings. Savings alone varied 3% (apartment 17% (single-family). When adding systems initially uninsulated, savings range 55% 80% Shading reduced loads by complexes provided predicted improvements floor dwellings next exposed roofs.

Towards improved understanding of cascading and interconnected risks from concurrent weather extremes: Analysis of historical heat and drought extreme events

PLOS Climate, Journal Year: 2022, Volume and Issue: 1(8), P. e0000057 - e0000057

Published: Aug. 10, 2022

Weather extremes can affect many different assets, sectors and systems of the human environment, including security, health well-being. that compound, such as heat drought, their interconnected risks are complex, difficult to understand thus a challenge for risk analysis management, because (in intertwined systems) impacts propagate through multiple sectors. In warming climate, extreme concurrent drought events expected increase in frequency, intensity duration, posing growing societies. To gain better understanding compound associated risks, we analyze eight historical Europe, Africa Australia. We investigated visualized direct indirect impact paths together with response adaptation measures. found most important cascading processes interlinkages centered around health, energy agriculture food production The key cascades result on economy, state public services ultimately also society culture. Our shows numerous far reaching consequences, potentially being able destabilize entire socio-economic systems. emphasize future research lies integration strong other large potential impacts, but which cannot resort experiences. Integrating approaches deal should furthermore consider effects possible mechanisms system resilience.

Compound mortality impacts from extreme temperatures and the COVID-19 pandemic

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: May 23, 2024

Abstract Extreme weather and coronavirus-type pandemics are both leading global health concerns. Until now, no study has quantified the compound consequences of co-occurrence them. We estimate mortality attributable to extreme heat cold events, which dominate UK burden from hazards, in England Wales period 2020-2022, during COVID-19 pandemic peaked terms mortality. show that temperature-related exceeded by 8% South West England. Combined, temperatures led 19 (95% confidence interval: 16–22 North England) 24 20–29 Wales) excess deaths per 100,000 population heatwaves, 80 75–86 Yorkshire Humber) 127 123–132 East snaps. These numbers at least ~2 times higher than previous decade. Society must increase preparedness for crises such as coinciding with pandemics.
