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.
