Most studies projecting human survivability limits to extreme heat with climate change use a 35 °C wet-bulb temperature (Tw) threshold without integrating variations in physiology. This study applies physiological and biophysical principles for young older adults, sun or shade, improve current estimates of introduce liveability (maximum safe, sustained activity) under future climates. Our physiology-based survival show vast underestimation risks by the Tw model hot-dry conditions. Updated...
Abstract This article investigates the effect of urban expansion and climate change impacts on heat stress (HS) for Arizona's (AZ; USA) two largest agglomerations, Phoenix Tucson metropolitan areas, under relatively dry moist warm conditions with Weather Research Forecasting (WRF)‐urban modeling system. We dynamically downscale contemporary summers, one moist, to their respective seasonal‐mean specific humidity across AZ. Urban HS are assessed by performing identical simulations each summer...
<title>Abstract</title> The heat stress limits for human survivability have been long defined by a 6-h exposure to wet-bulb temperature of 35oC. This definition has employed regularly the climate community understand threat on humans. However, we recently developed physiology-based model demonstrating that environmental thresholds, when accounting limitations evaporative cooling via sweating, and realistic hyperthermic thresholds stroke, may be cooler drier than previously thought. potential...
Fine-scale personal heat exposure (PHE) information can help prevent or minimize weather-related deaths, illnesses, and reduced work productivity. Common methods to estimate risk do not simultaneously account for the intensity, frequency, duration of thermal exposures, nor they include inter-individual factors that modify physiological response. This study demonstrates new whole-body net load estimations link PHE stress strain over time. We apply a human-environment exchange model examine...
Abstract. Flash floods are a recurrent hazard for many developing Latin American regions due to their complex mountainous terrain and the rainfall characteristics in tropics. These often lack timely high-quality information needed assess, real time, threats vulnerable communities extreme hydrometeorological events.

Cities are the most sensitive and vulnerable places to climate variability change weather-related extreme events given high population density, with aggravating factor that urban also suffers modifications due widespread replacement of natural surface altering local thermal conditions.

Numerical Weather Prediction models (NWP) have been used extensively since the ’40-’50s. Despite advances in field, representation and forecast of magnitude variability tropical processes is still a challenge. One steps to improve precipitation forecasts using limited-area evaluate which set physical schemes model domain configurations represent better way actual behavior observed tropics. We implemented, as part regional risk management strategy, two different operational weather strategies...
