Definition of stratosphere in US English:



  • 1The layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).

    • ‘Various methods were employed to collect data from the ocean's surface through the lower stratosphere.’
    • ‘Only the stratosphere is dry enough and with a long enough residence time (a few years) for the small anthropogenic inputs to be important.’
    • ‘Should further cooling of the Arctic stratosphere occur, increasing ozone losses can be expected for the next couple of decades.’
    • ‘A small proportion of this is Ozone, which is found in the stratosphere in a layer.’
    • ‘The current winter and early spring have been extremely cold in the Arctic stratosphere, leading to the potential for substantial ozone depletion there.’
    • ‘Just above the stratosphere lies the mesosphere.’
    • ‘The stratosphere extends above the troposphere to about 150,000 feet and is the region where the ozone layer is formed.’
    • ‘Like the Earth's atmosphere, Titan's atmosphere can be separated into the troposphere, stratosphere, and upper atmosphere.’
    • ‘It eventually reaches the stratosphere, where it causes a thinning of the ozone layer.’
    • ‘CFC molecules react with and destroy ozone in the Earth's stratosphere.’
    • ‘Ozone is commonly thought of in terms of the ozone layer high in the stratosphere.’
    • ‘The ozone layer is a thin layer of gas in the stratosphere which effectively screens out most of the harmful UV radiation in sunlight.’
    • ‘That's consistent with the fingerprint of ozone depletion plus greenhouse gases, which would cool the stratosphere and warm the surface.’
    • ‘It has been argued that not taking the cooling in the stratosphere properly into account can be one explanation for the trend differences.’
    • ‘The authors demonstrate that the presence of stronger westerly jets in the stratosphere causes tropospheric weather systems to track further toward the pole.’
    • ‘Like nacreous clouds, these usually form slightly above the troposphere, in the dry and ice-free stratosphere.’
    • ‘So while we are minding our business down here on the earth's surface, up in the stratosphere, ozone is continually being created and destroyed.’
    • ‘The resulting chlorine atoms that are generated catalyze the depletion of the ozone layer in the stratosphere.’
    • ‘Another important climate forcing, volcanic aerosols, can also give a similar opposing trend between the stratosphere and troposphere.’
    • ‘Nacreous and Noctilucent clouds form not in the part of the atmosphere in which we live, but much higher up, in the stratosphere and mesosphere.’
    1. 1.1informal The very highest levels of a profession or other sphere, or of prices or other quantities.
      ‘her next big campaign launched her into the fashion stratosphere’
      • ‘He's blasted the level of cuisine into the stratosphere.’
      • ‘Can this player muzzle the critics and take that one giant leap into the international stratosphere?’
      • ‘I like to say his standards were in the stratosphere, which is of course where they belong, journalistically.’
      • ‘At the Class X level, the percentages hit the stratosphere.’
      • ‘If you want a white shirt that will propel you into the fashion stratosphere, then look for something in a luxurious fabric which is fitted, yet floaty.’
