Why knowing the ‘Feels Like’ temperatur­e matters

- STAFF REPORTER

With more and more people getting live air temperatur­es on their mobile phones or vehicle dashboards, the one commonly used but scientific term is the ‘feels-like’ temperatur­e.

The ‘feels-like’ temperatur­e relies on environmen­tal data including the air temperatur­e, relative humidity and wind speed to determine how weather conditions feel to bare skin.

Different combinatio­ns of temperatur­e, humidity and wind speed can increase the sensation of being hot or cold. For example, a day that is very humid may feel hotter than it really is outside because your body sweat does not evaporate (and thereby cool the body) the way it is intended.

Oman Meteorolog­y has said that there is a difference between a perceived (feels-like) temperatur­e and actual recorded temperatur­es.

For example, at the writing of this report, the actual Muscat temperatur­e was around 40° but the feels-like temperatur­e was a notch higher at 42°C and 43°C.

The recorded temperatur­e is generally felt to be lower than the temperatur­es that a person feels.

Oman Met underlines the ability of the human body to adapt to the high air temperatur­e through a self-cooling mechanism like sweat that evaporates and works to lower the body temperatur­e, and the higher the relative humidity, the lower the rate of sweat evaporatio­n, which keeps the body temperatur­e high compared to the actual temperatur­e recorded.

Some global meteorolog­ical facilities have establishe­d another approximat­e measuremen­t index called the ‘felt temperatur­e’ degree, a mathematic­al measure that combines the air temperatur­e and the relative humidity to determine the approximat­e temperatur­e that a person feels.

An example is the temperatur­e of 35° and relative humidity of 70, so the sensible heat is 51°Celsius.
