Tropospheric ozone and NOx: A review of worldwide variation and meteorological influences

Environmental Technology & Innovation, Год журнала: 2022, Номер 28, С. 102809 - 102809

Опубликована: Июль 9, 2022

Tropospheric ozone (O3) has increased globally since the end of 20th century. Its formation undergoes complicated photochemical reactions and processes in lower boundary layer. As a result, changes O3 levels are not about one specific factor but combined process other effects such as anthropogenic emissions, topographic characteristics, meteorological influences. Consequently, published studies often show conflicting findings on levels. NOx is significant precursors generated during combustion processes. Therefore, despite efforts emission controls, reducing will guarantee downward trend. Furthermore, weather phenomena (e.g., anticyclones sea–land breezes) can enhance parameters that govern transport diffusion precursors. The review summarizes current knowledge emissions recent years. It helps to understand how regional features influence its precursors, which beneficial for efficient surface evaluation control.

Interplay between climate change and climate variability: the 2022 drought in Central South America

Abstract Since 2019, Central South America (CSA) has been reeling under drought conditions, with the last 4 months of 2022 receiving only 44% average total precipitation. Simultaneously to drought, a series record-breaking heat waves affected region. The rainfall deficit during October–November-December (OND) is highly correlated Niño3.4 index, indicating that OND partly driven by La Niña, as observed in previous droughts this To identify whether human-induced climate change was also driver deficit, we analysed precipitation over most impacted Our findings revealed pattern decreased past 40 years, although cannot definitively conclude trend exceeds what would be expected from natural variations. clarify if can attributed change, looked at 1-in-20-year low events same region models. models show severity decreases (i.e. they become wetter, opposite weather records), again not significant and compatible variability. Therefore, attribute change. Moreover, our analysis effective potential (evapotranspiration minus rainfall) shows that, models, increase temperature does compensate for but offset wetting, lead signal However, higher temperatures region, which have water availability late 2022, probably reduced period observations, increasing agricultural study did quantify effect. This means even though within variability, consequences are becoming more severe due strong extreme heat. case ongoing CSA clear example interplay between variability importance considering those aspects associated order understand particular or trends regional level.

Identification of weather patterns and transitions likely to cause power outages in the United Kingdom

Communications Earth & Environment, Год журнала: 2024, Номер 5(1)

Abstract Lightning strikes, snow, and wind are common causes of power system failures. Their frequency occurrence varies depending on weather patterns seasons. Here, we analyse the thirty pre-defined daily along with nearly 70,000 failures in United Kingdom between 2010 2019 to investigate predictability weather-induced outages. We identify high-risk pattern transitions for all Winter characterized by high speeds precipitation volumes responsible many instances outages caused wind, gale, lightning strikes. Weather moderate snowfall often linked snow ice. Because can be forecast reliably valuable lead time, clear links specific significantly improve preparedness broader European distribution network operators adverse conditions.

The influence of future weather pattern changes and projected sea-level rise on coastal flood impacts around the UK

Climatic Change, Год журнала: 2023, Номер 176(3)

Abstract When local extreme water levels surpass defences, the consequences can be devastating. We assess importance of sea-level rise and future weather pattern changes on UK coastal flood impacts. Historical classifications are matched with observed skew surges significant wave heights. Coastal-risk patterns then defined as ≥ 1% events in distribution exceeding warning threshold. combine this methodology projections frequency occurrences, to determine relative each risk. A deep low-pressure system situated west Ireland (WP29) has highest probability (6.3%) Newlyn’s present-day threshold; is projected increase under climate change 46.2% by 2050 RCP2.6. This work found that associated storm increasing decreasing frequency; a synoptic situation causing windy conditions north (WP23) will > 40% RCP8.5 end century (2079–2090). combining impact changing patterns, study dominates risk highly linked emission scenarios.

The UK has experienced recurring hydrological droughts in the past and their frequency severity are predicted to increase with climate change. However, quantifying risks of extreme is challenging given short observational record, multivariate nature large internal variability system. We use EC-Earth time-slice ensembles, which consist 2000 years data each for present-day, 2°C 3°C conditions relative pre-industrial, drive models river catchments Great Britain (GB) obtain a set plausible droughts. Since future warming certain, uncertainty drought mainly associated precipitation. Estimates unprecedented extremes show that chance summer month year drier than observed driest (1995) projected (from 9% present-day (PD) 18% warmer world (3C) southeast England).

Environmental Research Letters, Год журнала: 2023, Номер 18(6), С. 064048 - 064048

Опубликована: Май 17, 2023

Abstract How climate change will affect the spatial coherence of droughts is a key question that water managers must answer in order to adopt strategies mitigate impacts on resources. Water transfers from regions with excess those deficit are fundamental such strategies, but only possible if both not simultaneously under drought conditions—these relationships could warming world. Here, we use future simulations (under RCP8.5) streamflow (186 catchments) and groundwater level (41 boreholes) Enhanced Future Flows Groundwater (eFLaG) dataset analyse projected hydrological at national scale, Great Britain as an example. Joint conditional probabilities two being used characterise coherence. The results sensitive various uncertainties, including way defined. However, some findings emerge. In particular, for defined based current conditions, our show ‘far future’ (2050–2089) expected increase during summer everywhere country. During winter, however, may South-East, where sharpest rise winter likely occur. between shows more mixed picture, dependant season region. One important observation that, South-East summer, proportion coincide decrease. These provide valuable insight help inform their long-term strategy overcome droughts, feasibility inter-region conjunctive (surface groundwater) schemes. This flexible methodology has potential be applied other parts world shape strategic regional investments resilience droughts.
