The Troposphere

  • Temperature decreases with height - really, it does!

  • extends from surface to about 10-12 km

  • top of troposphere is called the tropopause-separates troposphere from stratosphere

  • where all the weather occurs

  • Inherently unstable - what does "unstable" mean?

  • rate of temperature decrease is about 6.5 degrees Celsius per 1 km (called the lapse rate)

  • the jet stream is located in the upper troposphere

  • higher is summer, lower in winter

    • tropopause height is proportional to mean tropospheric temperature

  • find the tropopause with real data.......
