are light. Based on maximum EDRs, two severe turbulent patches (EDR > 0.5

) are
detected by both aircraft and radar with wind shear, but they are not on the same flight
paths. With wind shear contribution, median and maximum radar EDRs evidently increase.

5 nm of flight paths for the selected 14 cases.
Comparing maximum intensity between aircraft and radar without wind shear, 8 of the 14
cases are in the same category. Seven of them are moderate turbulence. For 4 aircraft
estimated light turbulence cases, the radar tends to overestimate them as moderate (3 cases)
and severe (1 case) with wind shear contribution. After closer examination of the
overestimation case at 07:17 UTC on 25 June 2008, it is found that the maximum severe
