Introduction

Apparent temperature refers to the temperature perceived by the human body, which is not determined solely by air temperature but is a comprehensive metric that integrates multiple meteorological factors such as humidity, wind speed, and solar radiation. It reflects the state of heat exchange between the human body and the surrounding environment, and is typically lower or higher than the actual air temperature. When humidity is high, evaporation of sweat is hindered, causing apparent temperature to feel higher than the air temperature. When wind speed is high, heat dissipation accelerates, making it feel cooler than the actual temperature. Apparent temperature holds significant practical value in weather forecasting, heat stress assessment, outdoor activity planning, and built environment design.

Applicable Scene

Apparent temperature is widely applied in both daily life and professional fields. Meteorological departments frequently cite apparent temperature in heatwave or cold‑weather warnings to alert the public about risks of heatstroke or frostbite. In building design and HVAC engineering, apparent temperature is used to evaluate indoor thermal comfort and guide temperature and humidity control strategies. For outdoor sports and large event planning, apparent temperature helps determine whether conditions are suitable for outdoor activities. In occupational health and safety management, it is used to assess health risks for workers operating in high‑temperature or low‑temperature environments.

Pros: Apparent temperature incorporates multiple factors such as humidity, wind speed, and radiation, offering a more accurate reflection of human perception than air temperature alone, and providing more valuable reference information for both the public and professionals. In extreme weather warnings, apparent temperature effectively indicates heat stress or wind‑chill risks, helping to reduce health incidents like heatstroke and frostbite. In building and HVAC design, apparent temperature serves as a key criterion for thermal comfort evaluation, contributing to more pleasant indoor environments and improved comfort for occupants.
