The results of univariate Poisson regression showed that maximum air temperature (RR 1.007; 95% CI 1.005–1.010), mean atmospheric pressure(RR 0.995; 95% CI 0.993–0.997), water vapor pressure (RR 1.006; 95% CI 1.004–1.008), maximum wind speed (RR 0.974; 95% CI 0.950–0.998), sunshine duration (RR 1.004; 95% CI 0.999–1.010), and typhoon occurrence (RR 0.967; 95% CI 0.923–1.014) might be significant predictors ( P < 0.1).
