It is an example of pejoration
No, the word "surly" is not an amelioration. It typically has a negative connotation, meaning bad-tempered or unfriendly. An amelioration is a process where a word's meaning evolves to become more positive over time.
The root of the word "surly" is "sur," which means bad-tempered or unfriendly. The suffix "-ly" is added to form an adverb, turning "sur" into "surly," which means behaving in a bad-tempered and rude way.
Some variations of the word "sullen" include "morose," "gloomy," and "surly."
"Despite receiving the promotion, he remained surly and distant towards his colleagues."

To ameliorate is to improve. To pejorate is to worsen. So in this case, you would have to look at whether the connotative meaning of the word "doom" has worsened or gotten better. My best guess is that it has probably worsened, so it would be pejoration.
