How is the wind chill calculated?

The word thermal sensation to the reaction of the human body to the combination of the following parameters: dry temperature, average radiant temperature, wind speed and percentage of relative humidity, depending on our own body temperature and the insulation provided by the clothes and shoes we wear posts.

Although we usually look at the thermometer to know if it is hot or cold, as we see, We should not let ourselves be guided only by the data that it provides us to put on one wardrobe or another.

Measuring wind chill is not easy. This is something the explorer knew very well Paul Simple, which in the 30s realized that in the polar regions the speed of the wind was more dangerous than the temperature of the place. The human body uses the wind as a natural refrigerant, which can be a relief in the hottest months of the year, but in winter it can make us feel really bad.

In this table you can see what is the real temperature we feel in winter taking into account the temperature and wind speed:

They are really low temperatures, right? Of course, in addition to the climatic factors, it must be taken into account that our own body temperature can vary depending on our state of health, diet, and activity that we are doing at that moment. Thus, it is common for us to bundle up in the morning to go for a ride on a bicycle, and to return home a little less protected due to the heat that our body has generated during exercise.

So far we have talked about the temperatures and the wind, but humidity is also an important factor. During the cold months a high degree of humidity can make us feel very uncomfortable; Even here where I live I have heard people say that the cold enters your bones, causing that, no matter how much you protect yourself, you will be cold when the thermometer reads about ten degrees. On the other hand, in summer the opposite can happen: the higher the humidity, the hotter you can feel.

So, to get the right type of clothes you should wear today, don't hesitate to take a look at your weather station.
