I have found the information submitted by Clifford H. Prator, professor of English, University of California, in his research paper published in the book "Teaching English as a Second Language".
He goes on to say that the adjectives of temperature hot, warm, cool and cold are illogical in English.He was talking about the weather
He cited an example to show how their use is illogical:
"If the temperature starts falling, we cannot say that 'It is hot', 'It is warm', 'It is cool', and 'It is cold'. Instead, we have to say "It is hot", "It is getting cool" , "It is cold" – Omitting warm. And a natural rising progression would be "It is cold", "It is warming up" and 'It is cold' – leaving out cool"
I would like to know how native speakers describe the falling sequence of the temperature and the rising progression since the professor's findings on the weather in the research paper are considered wrong by them
