Real feel意思

"Real feel" or "real feel temperature" is a term used to describe the perceived temperature that takes into account the combined effects of the actual air temperature, humidity, wind speed, and other factors that influence how hot or cold the air feels to the human body. It is also known as the "feels like" temperature or "apparent temperature."

The human body loses heat through various mechanisms, such as conduction, convection, radiation, and evaporation. The real feel temperature attempts to quantify how these factors affect the body's thermal comfort. For example, high humidity can reduce the ability of the body to cool itself through evaporation of sweat, making it feel hotter than the actual air temperature would suggest. Similarly, wind can accelerate heat loss from the body, making it feel colder.

Meteorologists and weather forecasters use various formulas and algorithms to calculate the real feel temperature, which can be reported to the public alongside the standard air temperature. These calculations can be done manually or using specialized software or tools.

The concept of real feel temperature is particularly useful for people planning outdoor activities, as it provides a more accurate representation of the conditions they will experience rather than just the air temperature alone.
