Definition of mesopause in English:
mesopause
noun ˈmɛzə(ʊ)pɔːzˈmɛsə(ʊ)pɔːzˈmiːsə(ʊ)pɔːzˈmiːzə(ʊ)pɔːzˈmē-
The boundary in the earth's atmosphere between the mesosphere and the thermosphere, at which the temperature stops decreasing with increasing height and begins to increase.
Example sentencesExamples
- The normal altitude is about 100 km while the summer mesopause is situated around 87 km for about 4 month.
- Using data from TIMED/SABER, we studied the global behavior of the mesopause at solstice (northern-hemisphere summer).
- The figures give a climatology of prevailing horizontal winds at mesopause heights and Collm time series of mesopause wind parameters.
- The oscillations in the measured dayglow intensities in the mesopause region and the winds at ~ 87 km are resulting from the modulation caused by this wave in this region after a delay of 4-5 days.
- Some experiments were realized to verify the validity of the new technique and to provide the temperature profile in the mesopause region.
- The summer polar mesopause is the coldest part of the atmosphere, with temperatures reaching below 130K, in spite of being continuously sunlight.
- At the upper boundary of the mesosphere, the mesopause, the temperature is between 110°C, in summer, and 60°C, in winter.
- It is suggested that the wave-wave sum resonant interaction and the wave dissipation due to instability are two dominant dynamical processes that occur in the mesopause region.
- The MU radar can measure the diffusion coefficients in the mesopause region by observing meteor echoes.
- It is this alteration in the diffusivity of the mesopause region that allows structures in the electron density to persist at observable scales.
