英文摘要: Previous studies using satellite measurements showed evidence that subtropical upper troposphere/lower stratosphere ozone (O3 ) can be modulated by tropical intraseasonal variability, the most dominant form of which is the Madden Julian Oscillation (MJO) with a period of 30-60 days. Here we further study the MJO modulation in the upper troposphere/lower stratosphere O3 over the northern extratropics and the Arctic. Significant MJO-related O3 signals (13-20 Dobson units) are found over the northern extratropics (north of 30°N). The O3 anomalies change their magnitude and patterns depending on the phase of the MJO. Over the Arctic, the MJO-related O3 anomalies are dominated by a wave number 2 structure and are anticorrelated with the geopotential height (GPH) anomalies at 250 hPa. The latter is similar to the findings in the previous studies over subtropics and indicates that the Arctic upper troposphere/lower stratosphere O3 anomalies are associated with dynamical motions near the tropopause. The teleconnection from the tropics to the Arctic is likely through propagation of planetary waves generated by the equatorial heating that affects the tropopause height and O3 at high latitudes.
