Baghdad has the highest average annual temperature for every month, and (obviously) Syracuse has the lowest, with Shengxian in the middle. The a, b, and c values of the equations are highly similar, meaning that the sin wave of the average temperatures are almost identical.
Although I prefer a mild to warm climate, I would highly advise against traveling to either Baghdad or Shengxian for political or economical reasons.
