Here's an example for your question:
The climate zone of hometowns that lies on the southeast sides of the nations like USA and China(e.g. Florida,Carolina,Hong Kong,Macau), is in a sub-tropical zone.
The reason why it is sub-tropical is because that it is usually hot and humid in summer with the temperature of 25°C to 31°C, while in winter it is mild to chilly. Rainfall is also present with average to high amount during summer.
Hope it helps!
