PLA flights in Taiwan's ADIZ each month, by region
A stacked column chart shows the number of PLA flights in Taiwan each month, by region. There is a significant spike in August 2022, where an annotation points out Nancy Pelosi visited Taiwan, and again in April, when Tsai Ing-Wen visited the US. Before August, the majority of flights were in the Southwest ADIZ, but Median Line crossings are much more frequent from August 2022 onward.
