Recent Studies Related to Clear Air Turbulence

  • R. M. Endlich
  • R. L. Mancuso


This is a brief review of recent work at Stanford Research Institute related to clear air turbulence. Four separate topics are covered:
  1. (1)

    Computer techniques of forecasting the probability of encountering CAT

  2. (2)

    The climatology of CAT

  3. (3)

    Analysis of high resolution vertical wind profiles

  4. (4)

    Lidar observations of atmospheric structure indicating air motion.


Work on satellite cloud observations as indicators of CAT is not discussed. This approach, while promising, will not come into its own until higher resolution TV and IR coverage is available on a continuous basis, i.e., from synchronous satellites. (Viezee, et al 1966)
