The Chinese word 帕萨特 is formed through phonetic transcription, where each character is selected to mimic the sounds of the foreign term "Passat": 帕 (pà) approximates "Pa", 萨 (sà) approximates "ssa", and 特 (tè) approximates "t", resulting in a sequence that replicates the original pronunciation without conveying inherent meaning from the characters themselves.
