The Increase in Urban Heat Due to Global Warming Can be Significantly Affected by the Structure of the Land Use and Land Cover

International Journal of Climatology, Volume 44, Issue 15, Page 5381-5397, 15 December 2024.
Urban heat will increase significantly in the future, although the spatial–temporal variability of these changes can differ significantly. Our results indicate that variability of the heat can be attributed not only to atmospheric conditions, but also to a degree of fragmentation of land use and land cover.

High‐resolution dataset of nocturnal air temperatures in Bern, Switzerland (2007–2022)

Geoscience Data Journal, Volume 11, Issue 4, Page 623-637, October 2024.
We present a high‐resolution dataset covering the mean air temperatures of every night in the summers of 2007–2022 in a medium‐sized city in Europe. The dataset is conducted using a land use regression approach that follows the principles of open data and low costs.

The hectometric modelling challenge: Gaps in the current state of the art and ways forward towards the implementation of 100‐m scale weather and climate models

Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 765, Page 4671-4708, October 2024 Part B.
Research shows that 100‐m scale models can improve the representation of several meteorological phenomena. Here, improved resolution of either the atmosphere or the surface is important for modelling urban hazards. This review article surveys the challenges in transitioning these models into practical forecast systems and suggests ways forward.

Development of LCZ mapping method combining GIS with machine learning [PDF]

E3S Web of Conferences
Local Climate Zones (LCZ) have been used worldwide in the field of urban climate. In most previous studies, LCZ maps—zoning maps for LCZ categories—were generated using the WUDAPT Level 0 method with satellite images and machine learning techniques.

Role of Clouds in the Urban Heat Island and Extreme Heat: Houston‐Galveston Metropolitan Area Case

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 17, 16 September 2024.
Abstract This study examines the influence of shallow cumulus clouds on the excessive summertime heat in the Houston‐Galveston metropolitan area, a coastal urban area in the warm Southeast United States. Specifically, it aims to improve our understanding of how both the clouds and the relatively cool, moist afternoon sea breeze impact the Urban Heat ...

Cool Roofs Could Be Most Effective at Reducing Outdoor Urban Temperatures in London (United Kingdom) Compared With Other Roof Top and Vegetation Interventions: A Mesoscale Urban Climate Modeling Study

Geophysical Research Letters, Volume 51, Issue 13, 16 July 2024.
Abstract Comprehensive studies comparing impacts of building and street levels interventions on air temperature at metropolitan scales are still lacking despite increased urban heat‐related mortality and morbidity. We therefore model the impact of 9 interventions on air temperatures at 2 m during 2 hot days from the summer 2018 in the Greater London ...

Climatological analysis of urban heat island effects in Swiss cities

International Journal of Climatology, Volume 44, Issue 5, Page 1549-1565, April 2024.
This work presents a comprehensive study of the Swiss urban climate during the last 6 years. We performed simulations over the entire alpine country and analysed the 10 largest cities to provide an accurate and up‐to‐date picture. Abstract This work presents a high‐resolution spatiotemporal analysis of the urban heat island (UHI) effect in Swiss cities

Local Climate Zones Classification Applied to a Brazilian Amazon City

Urban Science
Urban elements influence atmospheric flow, turbulence, and the local microclimate, modifying the transport and composition of pollutants. However, although this focus on cities is crucial for managing climate change, our knowledge of most cities in the ...

Urban Landscape Change Analysis Using Local Climate Zones and Object-Based Classification in the Salt Lake Metro Region, Utah, USA

Remote Sensing, 2019
Urban areas globally are vulnerable to warming climate trends exacerbated by their growing populations and heat island effects. The Local Climate Zone (LCZ) typology has become a popular framework for characterizing urban microclimates in different ...
