| Abstract: | Researchers have paid much attention to the influence of the tropical zonal wind quasi-biennial oscillation (QBO) on tropical methane,while generally ignoring the change in extra-tropical methane.The present study analyzed the interannual changes in the methane mixing ratio in extra-tropics of both the Southern Hemisphere (SH) and Northern Hemisphere (NH) using Halogen Occultation Experiment (HALOE) satellite data.The results show that interannual changes in extra-tropical methane exhibit QBO features in bo... |
