I found a distinct lack of education in initial line training of the numerous cadets about turbulence. There is so much data available on modern a/c. Some useful parameters are the winds and TAT/SAT when in cruise. See one or the other jumping all over the place gives some hints. See both of them dancing around and it's odds on you're going to hit homer lumpy stuff.
I noted this in reading a report about an overspeed in descent that led to an incident and cabin crew injury. The clue was in the quickly increasing headwind during the descent. Then came the overspeed, then came the 'incident'. All the time VNAV remained on profile and the lateral & vertical magenta lines were front & centre. It's missing education. When you have captains at 3000hours and 4 years experience and LTC's at only 1-2 years more, it might be construed that the knowledge data base of some is not as full as it was in days of yore; therefore there is less to pass on.
