In recent decades, urbanization and the dramatic increase in urban populations have exacerbated heat island effect. At present, much attention has been paid to causes patterns of However, there are few quantitative studies on impact By extracting post-world climate data, DEM land use data for 20 years between 2001 2020, this paper first variation pattern spatial distribution characteristics islands New York State, summarizes seasonal temperature, then uses Giles formula calculate Tom's discomfort index evaluate human thermal comfort, evaluates effect sensory comfort. The results show that time scale, surface temperature study area generally showed a slow upward trend over past years. For example, July, maximum minimum temperatures increased by 3.2 °C 4.1 °C, respectively. most areas were distributed City agglomeration, especially from May October, when was particularly obvious. map obvious high temperatures.

Abstract The study analyzes the underlying reasons and ensuing consequences of Chattogram city's development in Bangladesh, which diverges from principles sustainable development. This research employs mixed‐method approaches incorporating primary data to achieve its objectives. is based on a survey, interview, author's experience, participatory observation city. Furthermore, it critically examines existing literature develop theoretical understanding environmental nexus. results indicate that expansion urbanization industrialization proceeding at rapid pace; however, occurring an uncoordinated unsustainable manner neglects protection. Consequently, falls short aligning with sustainability liable induce negative ramifications environment, human health, biodiversity, climate. pinpoints several factors contributing degradation, including mismanagement, non‐existence master plan, illiteracy, absence carbon emission objectives, haphazard urbanization. Importantly, issue has been exacerbated due inadequate focus developmental process. Therefore, findings this perspective required comprehend address degradation In addition, comprehensive strategy policy recommendations proposed are likely be efficacious curbing other developing cities.

Urban heat island phenomenon in a desert, coastal city: The impact of urbanization

Urban Climate, Journal Year: 2024, Volume and Issue: 56, P. 102016 - 102016

Published: June 28, 2024

The state of Qatar has been experiencing rapid urbanization with around 85% its population residing in Doha. country faces notable challenges related to the Urban Heat Island (UHI) effect, which is exacerbated by hot and humid desert climate. This study focuses on analyzing UHI phenomenon Doha, utilizing observed meteorological data Weather Research Forecasting model (WRF v4.5). Two land use cover (LULC) datasets from 2001 2018 are employed, simulations conducted using different urban canopy models. LULC includes 100 m resolution information that categorizes areas into 11 local climate zones. Results indicate significant intensity during both winter summer periods (up 6.5 °C), differences between daytime nighttime temperatures. In agreement observations, predicts not only a strong effect nighttime, but also Cool Doha −5.8 °C summer). impact various parameterization schemes simulation accuracy highlighted. building energy demonstrates superior performance predicting temperature relative humidity period. spatial distribution heat index illustrates intensified warming city.

Abstract This study examines the characteristics of urban heat island (UHI) in Dhaka, densely populated capital city Bangladesh under influence South Asian monsoon, and its interaction with waves. For this, meteorological data at Dhaka (urban) Madaripur (rural) stations reanalysis for period 1995–2019 are used analysis. Here, UHI intensity is defined as urban-rural difference 2-m temperature, a wave phenomenon which persists two or more consecutive days daily maximum temperature exceeding 90th percentile. The an increasing trend over past 25 years (0.21 °C per decade). average 0.48 °C. strongest winter (0.95 °C) weakest monsoon season (0.23 °C). In all seasons, 2100 LST. 2.15 Through multiple linear regression analysis, relative importance previous-day (PER), wind speed, humidity (RH), cloud fraction affect examined. pre-monsoon season, RH most important variable followed by PER. predominantly variable. post-monsoon winter, PER RH. occurrence frequency waves shows statistically significant (5.8 It found that associated mid-to-upper tropospheric anticyclonic-flow high-pressure anomalies low-to-mid season.

Land use land cover change (LULC) significantly impacts urban sustainability, planning, climate change, natural resource management, and biodiversity. The Chattogram Metropolitan Area (CMA) has been going through rapid urbanization, which impacted the LULC transformation accelerated growth of sprawl unplanned development. To map those sprawls resources depletion, this study aims to monitor using Landsat satellite imagery from 2003 2023 in cloud-based remote sensing platform Google Earth Engine (GEE). classified into five distinct classes: waterbody, build-up, bare land, dense vegetation, cropland, employing four machine learning algorithms (random forest, gradient tree boost, classification & regression tree, support vector machine) GEE platform. overall accuracy (kappa statistics) receiver operating characteristic (ROC) curve have demonstrated satisfactory results. results indicate that CART model outperforms other models when considering efficiency designated region. analysis conversions revealed notable trends, patterns, magnitudes across all periods: 2003–2013, 2013–2023, 2003–2023. expansion unregulated built-up areas decline croplands emerged as primary concerns. However, there was a positive indication significant increase vegetation within area over 20 years.
