What is the temperature of the weather forecast, and why is it different from the sense of body?

Many of us may watch the weather forecast after the news broadcast every night when we eat, so as to know the approximate temperature tomorrow, or wake up every morning and turn on our mobile phone to see today's outdoor temperature to choose the thickness of clothes. But every time we feel that the temperature in the weather forecast is always different from our somatosensory temperature. ? Theoretically, the temperature reported in weather forecast refers to the temperature of free-flowing air in natural state. Under normal conditions, it should be said that this temperature is disturbed by human factors as little as possible and by other factors in the natural environment except the sun temperature as little as possible. Therefore, the temperature reported in the weather forecast only represents the degree of cold and warm in the air, but not the outdoor temperature of the human body.

The external temperature parameter perceived by human body is called somatosensory temperature in academic circles. As we all know, our normal body temperature is around 37 degrees Celsius, and the temperature we feel outdoors is often influenced by humidity, wind speed, solar radiation, our daily mood and our clothes. It is precisely because of these factors that we have different perceptions of cold and warm after going out every day. ? At the same time, we also understand that it is difficult for us to shield the external interference factor such as body temperature. Scientists have found that people will not feel sultry in an environment of about 30 degrees Celsius, and when the relative humidity in the air increases to about 80%, people living in such an environment will often have the possibility of heatstroke.

So, whenever you go out to feel the outside temperature, don't think the weather forecast is deceiving you. The weather and temperature it reports are completely different from what you perceive.
