Explanation
啊 is a soft sentence-final particle. It warms up statements, questions and commands so they sound less blunt, and it marks exclamations ('so hot!'). In speech its sound changes with the preceding final: after -o/-a/-e it becomes 呀 (ya), after -u/-ao it becomes 哇 (wa), after -n it becomes 哪 (na) — but in writing it is normally all written 啊. It carries no dictionary meaning; drop it and the sentence is still grammatical, just blunter.

Note
Spoken 呀/哇/哪 are just sound variants of 啊; standard writing uses 啊.
