Wet bulb temperature is a measure of how cool it feels when evaporation cools you down. Imagine wrapping a wet cloth around a thermometer. As the water evaporates, it cools the thermometer, showing a lower temperature than the actual air temperature. This reading is the wet bulb temperature. It's important because it combines heat and humidity, indicating how hot and uncomfortable it feels to humans. In very high wet bulb temperatures, our bodies struggle to cool down through sweating, which can be dangerous. It's a critical measure for understanding heat stress and ensuring safety during extreme weather.
