The fundamental emphasis of this research was to develop a technique which would be a significant improvement over those currently used for flight planning to avoid clear air turbulence (CAT). The technique should, ideally, be both quantitative in determining potential intensity and specific in locating regions of relatively high risk.

This technique is the specific clear air turbulence risk (SCATR) index. This index shows some promising results. The improvements seen using hand analyzed data, as a result of the more realistic representation of the vertical shear of the horizontal wind, are also realized in the data analysis used in the PROFS/CWP : J.

It is usually invisible and so can be dangerous as clear air it can be detected by radar or seen by chance as billow clouds when the humidity is such that the rising air in a vortex leads to condensation as cloud and the falling air leads to evaporation (see Figure 4).
