Is the direction of the wind as important as the wind speed? And does the direction of the wind have an impact on the temperature in the United Kingdom? So that's why, is the principle now clear to you? It's no coincidence that you feel cold when the wind starts to blow.īy now you know that wind chill has nothing to do with a wind turbine, but is the name given to the effect of the wind on the felt temperature. Without this layer, our skin is then directly in contact with colder and drier air.* The consequences? The skin gradually dries out as it warms the air to restore this balance… which immediately cools our body (this requires a lot of energy). But this small insulating protection is perpetually blown away when it's windy! The principle is physical and rather simple, but not obvious: when there is no wind, a thin layer of warm air moistened by the body forms on the surface of the skin. It is simply the sensation of cold that the wind causes on a living organism that radiates heat (like your body), while there is no change in the actual air temperature. The wind chill is the correct term, better known in popular parlance as the felt temperature. More importantly, does wind chill have anything to do with wind turbines? Apart from the association with wind, not really… Does wind speed affect the felt temperature? The higher the wind speed, the greater the cooling. The feeling of cold is therefore reinforced when the wind joins the party, even with the same temperature. With a strong northerly wind, the felt temperature changes dramatically! The weather is important, especially in the United Kingdom where the climate is varied (but less so than in the northernmost regions of the world). On the one hand, the physiological perception of temperature varies from person to person, but on the other hand, it varies according to atmospheric conditions.Īs you know, a dry, calm, and sunny 20 degrees does not feel at all the same as 20 degrees with strong wind and rain. When we talk about air temperature or temperature under shelter, we are talking about the temperature measured with a thermometer or a probe placed 1.5 metres above the ground, inside an open-air shelter, well protected from the wind and the weather.īut the reality is often different, precisely because of the winds and the weather. Before discussing the influence of wind speed on the felt temperature it would be useful to have a better understanding of what we are talking about, right? So let's start with an update on the weather.
