(a) Altitude-time section of potential temperature concatenated for three locations: 37.5°E and 69°S for 10–14 February 2017, 49°E and 67.5°S for 15–24 February 2017, and 69°E and 66°S for 15–24 February 2017. Downward solid (broken) arrows indicate major (minor) increases in potential temperature, suggesting the decent of air with higher potential temperatures. (b) Time series of beryllium-7 concentration observed on the Shirase from 11 February to 4 March, corresponding to.
