Automated mapping process of frontal area and thermal potential indexes: GIS algorithm development and implementation Urban Clim. (IF 6.4) Pub Date : 2024-01-12 Ana Paula Oliveira Favretto, Léa Cristina Lucas de Souza, Daniel Souto Rodrigues
The impacts of urban areas on microclimate conditions are well-known and highlight the importance of climatological guided urban planning. The growth and evolution of Geographic Information Systems (GIS) have set a backdrop for implementing strategies to apply urban climatological knowledge in planning daily practice. This research brings algorithms to automate the Frontal Area Index (FAI) and Thermal

Seasonal spatial variations of urban methane concentrations in a medium-sized city determined by easily measure variables Urban Clim. (IF 6.4) Pub Date : 2024-01-11 Victoria S. Fusé, Carla S. Stadler, Lucas Chiavarino, Natasha Picone, Santiago Linares, Sergio A. Guzmán, M. Paula Juliarena
The concentration of methane (CH4) in the urban atmosphere results from a balance between sources and sinks, as well as meteorological and topographical conditions that affect CH4 dispersion in the environment. Different geophysical, technical and demographic factors will determine the CH4 concentration in each city, and therefore further local research should be undertaken. The present study analyzes

Development of a computational fluid dynamics model adopting a nested grid system: Flow simulations for ideal and real urban settings Urban Clim. (IF 6.4) Pub Date : 2024-01-12 Soo-Jin Park, Jae-Jin Kim
We incorporate a nested grid system into a computational fluid dynamics (CFD) model based on the Reynolds-averaged Navier-Stokes equations. First, we evaluate the CFD model by comparing the results simulated in an array of aligned buildings using one- and two-way nested and non-nested coarse (same grid size as the parent domain) and fine grid (same grid size as the child domain) systems. The two-way

Identification and analysis of evolution characteristics of flash drought based on three-dimensional perspective: A case study in the Jialing River basin Urban Clim. (IF 6.4) Pub Date : 2024-01-13 Changqing Meng, Zijiao Dong, Keying Liu, Yuankun Wang, Yuqing Zhang, Yulong Zhu
Flash drought is an extreme hydrological event, with a short foreseeable period and high destructive force, and it is difficult to monitor. Flash drought aggravates the risk of extreme disasters and seriously threatens agricultural production and urban water security. To explore the temporal and spatial dimension evolution and identifiable characteristics of flash drought, the present study proposed
