Abstract
Based on the temperature and dust opacity data from the Mars Reconnaissance Orbiter/Mars Climate Sounder and the OpenMars reanalysis, we report an extremely strong quasi-20-sol wave (Q20SW) during the global dust storm (GDS) in Mars Year (MY) 34. After the onset of the GDS in MY34, the amplitude of the Q20SW reaches approximately 12 K in temperature, which is the strongest from MY29 to MY35. By analyzing the Eliassen-Palm fluxes of the Q20SW and their divergences, we conclude that the Q20SW is enhanced due to the unseasonal temperature increase caused by the GDS. Moreover, we find a strong eastward propagating oscillation with a period of 12–16 sols and a wavenumber of 1 exists in the dust opacity after the commencement of the GDS. This indicates that the strong Q20SW could also modulate the dust variation in the middle latitudes during the GDS.
期刊介绍：
The Journal of Geophysical Research Planets is dedicated to the publication of new and original research in the broad field of planetary science. Manuscripts concerning planetary geology, geophysics, geochemistry, atmospheres, and dynamics are appropriate for the journal when they increase knowledge about the processes that affect Solar System objects. Manuscripts concerning other planetary systems, exoplanets or Earth are welcome when presented in a comparative planetology perspective. Studies in the field of astrobiology will be considered when they have immediate consequences for the interpretation of planetary data. JGR: Planets does not publish manuscripts that deal with future missions and instrumentation, nor those that are primarily of an engineering interest. Instrument, calibration or data processing papers may be appropriate for the journal, but only when accompanied by scientific analysis and interpretation that increases understanding of the studied object. A manuscript that describes a new method or technique would be acceptable for JGR: Planets if it contained new and relevant scientific results obtained using the method. Review articles are generally not appropriate for JGR: Planets, but they may be considered if they form an integral part of a special issue.
