It is similar to turbopause in seasonal and latitudinal variations, providing an almost global analysis of turbopause on the basis of satellite measurements rather than localized detection. Previous studies of \u201cwave turbopause\u201d were based on standard deviation of temperature, which is an integrated measure of wave activity. In this study, we distinguish different atmospheric waves and investigate their influences on \u201cwave turbopause\u201d. By comparing the altitude of \u201cwave turbopause\u201d with peak height of amplitude (PHA) for gravity waves and 6.5 days waves (6.5 DWs), whose period is approximately 6.5 days in the mesosphere and lower thermosphere, we find that the seasonal variation in altitude of \u201cwave turbopause\u201d is higher at the winter pole and lower at the summer pole, correlated with PHA for 6.5 DWs but anti-correlated with PHA for gravity waves. We infer that gravity waves reach saturation and break at lower altitudes in the winter when Brunt\u2013Vaisala frequency is also lower between 80 and 100 km altitudes. Finally, the results may imply that seasonal variations of the \u201cwave turbopause\u201d are driven mainly by 6.5 DWs.<\/jats:p>","DOI":"10.3390\/rs15030800","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T05:33:53Z","timestamp":1675229633000},"page":"800","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Different Influences on \u201cWave Turbopause\u201d Exerted by 6.5 DWs and Gravity Waves"],"prefix":"10.3390","volume":"15","author":[{"given":"Wei","family":"Ge","sequence":"first","affiliation":[{"name":"Unit No. 95806 of Chinese People\u2019s Liberation Army, Beijing 100076, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0378-2717","authenticated-orcid":false,"given":"Zheng","family":"Sheng","sequence":"additional","affiliation":[{"name":"College of Meteorology and Oceanography, National University of Defense Technology, Changsha 410073, China"},{"name":"Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters, Nanjing University of Information Science and Technology, Nanjing 210094, China"}]},{"given":"Yingying","family":"Huang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Applied Meteorology, Beijing 100029, China"}]},{"given":"Yang","family":"He","sequence":"additional","affiliation":[{"name":"College of Meteorology and Oceanography, National University of Defense Technology, Changsha 410073, China"}]},{"given":"Qixiang","family":"Liao","sequence":"additional","affiliation":[{"name":"College of Meteorology and Oceanography, National University of Defense Technology, Changsha 410073, China"}]},{"given":"Shujie","family":"Chang","sequence":"additional","affiliation":[{"name":"College of Ocean and Meteorology, Guangdong Ocean University, Zhanjiang 524088, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"28769","DOI":"10.1029\/1998JD200002","article-title":"Seasonal Variation of the Turbopause: One Year of Turbulence Investigation at 69\u00b0 N by the Joint University of Troms\u00f8\/University of Saskatchewan MF Radar","volume":"103","author":"Hall","year":"1998","journal-title":"J.
