In weather forecasts, when it is stated that a temperature of 41 degrees Celsius "feels like" 50 degrees Celsius, it refers to the heat index or apparent temperature. The heat index takes into account not only the actual air temperature but also the effect of humidity on how the temperature feels to the human body.
Humidity affects our ability to cool down through sweat evaporation. When the air is humid, sweat doesn't evaporate as easily, making us feel hotter than the actual temperature. The heat index is a measure that combines temperature and humidity to provide an approximation of how the weather feels to us.
So, in this case, even though the actual air temperature is 41 degrees Celsius, the combination of high temperature and high humidity makes it feel as if the temperature is 50 degrees Celsius. This indicates that the heat and humidity together create a more intense and uncomfortable sensation for human perception. It serves as a warning to people that they should take extra precautions in such conditions, such as staying hydrated, seeking shade or air conditioning, and avoiding strenuous outdoor activities.
