Wet Bulb Temperatures
What are Wet Bulb Temperatures? Wet bulb temperature measures the combined effect of heat and humidity, representing the lowest temperature achievable by evaporating water into the air . It is measured using a thermometer with a water-soaked cloth over its bulb, and it always reads lower than or equal to the dry bulb temperature. A higher wet bulb temperature indicates higher humidity, which hinders evaporation and reduces the body's ability to cool itself through sweating. This makes it a critical metric for assessing heat stress on humans and is often higher than the commonly reported heat index. Why Wet Bulb Temperatures are important Humidity and Evaporation : The wet bulb temperature is essentially a measure of how well water can evaporate into the air. Human Cooling : Our bodies cool through the evaporation of sweat. High wet bulb temperatures mean less evaporation, making it harder to cool down and leading to dangerous heat stress. Heat Str...
