The “perceived temperature” is roughly comparable to the so-called felt temperature, which
additionally takes into account the radiation effect of the sun, light refection from the clouds, the
light wavelength, etc.

It can be seen from this that, depending on the ratio of temperature to humidity, there are clearly
bounded areas, which are defined as a comfortable or an uncomfortable climate. Hence, one
finds a humidity level of 30% at a temperature of 77°F (25ºC), for example, to be too dry (e.g.
heating air) and one above 60% to be oppressive.
