Outline of Final Research Achievements

Observational features of atmospheric fields up to the lower thermosphere during a vortex-split type major sudden stratospheric warming event in February 2018 were analyzed to show that the warming was relatively modest, although the upward propagation peak of planetary waves was comparable to that during a major warming event in January 2009. Furthermore, the representation of dynamical fields in the stratosphere and lower mesosphere was compared within six major global atmospheric reanalysis datasets and with recent satellite observations. It was found that the difference in the zonal wind field displayed a prominent equatorial maximum that increased with height, while that in the temperature field reached a minimum near the Equator and was largest in the polar regions.

Academic Significance and Societal Importance of the Research Achievements

成層圏突然昇温現象は、冬季成層圏極域の気温が急激に昇温する現象であるが、その影響は地表付近やさらに高層の大気にも及ぶと考えられており、本研究で行った詳細な解析により、その影響の一端が明らかとなった。また、再解析データは、各国の気象庁で作成され、精度と信頼度の高い全球気象データとして大気科学研究に広く使われているが、本研究により、再解析データ間で無視できない違いがあることが明らかとなり、このような相違が、気候変動の将来予測など、これまで行われている研究に大きな影響を与える可能性がある。
