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. Under waves, synergistically intensified both daytime nighttime (nighttime only) (monsoon) decreases favorable synergistic UHI-heat interaction.

Abstract Key message A model for sustainable planning of urban tree stocks is proposed, incorporating growth, mortality, replacement rates and ecosystem service provision, providing a basis stocks. Many recent studies have improved the knowledge about trees, their structures, functions, services. We introduce concept management analogous to forestry developed by Carl von Carlowitz others. The main drivers are species-specific diameter growth functions mortality rates. Based on initial stock options annual replanting, shift distribution number trees per age class can be predicted with progressing time. Structural characteristics such as biomass leaf area derived from dimensions that related carbon sequestration or cooling. To demonstrate potential dynamic model, we first show how different quantitatively assessed sustainability indicators compared target stock. Second, derive proxy variables services (e.g. sequestration, deposition shading) given class. Third, scenario analyses selected may combining complementary species. exercise one aspect (cooling) (temperature mitigation) an example. approach integrates mosaic pieces resulting presented makes this available discuss relevance ecologically economically management, in view urbanization environmental changes.

At present, understanding the synergies between Surface Urban Heat Island (SUHI) phenomenon and extreme climatic events entailing high mortality, i.e., heat waves, is a great challenge that must be faced to improve quality of life in urban zones. The implementation new mitigation resilience measures cities would serve lessen effects waves economic cost they entail. In this research, Land Temperature (LST) SUHI were determined through Sentinel-3A 3B images eight capitals Andalusia (southern Spain) during months July August years 2019 2020. objective was determine possible or interaction LST SUHI, as well region classified highly vulnerable climate change. For each Andalusian city, atmospheric variables ambient temperature, solar radiation, wind speed direction obtained from stations Spanish State Meteorological Agency (AEMET); data quantified both periods normal environmental conditions waves.
