The correlation between vorticity and IIBT (contour) and the mean wind field of the winter half year (unit: m s−1). (a) For 700 hPa and (b) for 500 hPa. The different shadings from light to dark have passed the significance test with more than 90%, 95%, and 99% confidence level, respectively; the red (blue) areas denote positive (negative) correlation areas, and the area encircled by yellow line is the TP (the same for the following context).
