Projections of Meteorological Drought and Potential Evapotranspiration Using the RegCM4 Over Northeastern Iran

International Journal of Climatology, EarlyView.
We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer

Comparison of mediating effects of air pollutants on urban morphology and urban heat Island intensity at block scale

Scientific Reports
The urban heat island effect seriously challenges the sustainability and livability of urban development. Air pollutants (AP) may play a mediating role in the impact of urban morphology (UM) on the canopy layer urban heat island intensity (CLUHII) and ...

The Urban Heat Island Effect in the City of Toronto

Procedia Engineering, 2015
AbstractThe increasing awareness of theurban heat island (UHI) effect has raised the attention for monitoring and evaluating the outdoor thermal comfort in cities worldwide. The urban microclimate is an important factor for pedestrians’ health, but it also affects the urban air quality, the energy use of buildings, citizen wellbeing, and urban ...

Climatology and Trends of Sub‐Daily Precipitation Extremes in Croatia

International Journal of Climatology, EarlyView.
Sub‐daily extreme precipitation indices reveal pronounced spatial variability, with the highest intensities and frequencies across the Adriatic region and the highlands. Seasonal and diurnal patterns highlight distinct regional behaviour, including summer maxima over the continental interior and nocturnal or early‐morning peaks along the Adriatic coast.

Exploration of heat island effect assessment methods for future land simulation scenarios: a case study of Beijing

Humanities & Social Sciences Communications
The urban heat island effect has significantly impacted people’s production and daily lives. This study explores a methodology for evaluating the degree of heat island evolution in future land use scenarios. This study established four different land-use

Urban Heat Island Effects in Tropical Climate

, 2020
This paper reviews some of the characteristics of urban climates and the causes and effects of urban heat island (UHI) issues in the tropical climate. UHI effect is a kind of heat accumulation phenomenon within the urban areas due to urban construction and human activities. It is recognized as the most evident characteristic of urban climate.

Characterising City Scale Heat Climatology for Australian Climate Zones

International Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Daily variation of urban heat island effect and its correlations to urban greenery: A case study of Adelaide

, 2017
Urban structure and landscape cause an artificial temperature increase in cities, known as the urban heat island effect. The magnitude of such urban–rural temperature difference varies in daily and seasonal basis.

Effects of Topography on the Urban Heat Island

, 2005
The UHI development for the ZGA was modelled with the three dimensional non-hydrostatic mesoscale model MEMO, for two different cases (9-10 June and 17-23 July 2004). The results demonstrated a successful multi-day simulation in the ZGA and a good agreement with the available observations.
