Re: Tropical Storm Hermine Develops in Southwestern Gulf of Mexico

Can anyone explain the extraordinary increase in wind speed on this dropsonde report? A Low Level Jetstream is the only explanation I can come up with other than equipment failure.
Level Wind Direction Wind Speed
1014mb (Surface) 130° (from the SE) 17 knots (20 mph)
1009mb 135° (from the SE) 22 knots (25 mph)
984mb 130° (from the SE) 23 knots (26 mph)
971mb 130° (from the SE) 22 knots (25 mph)
964mb 185° (from the S) 14 knots (16 mph)
961mb 105° (from the ESE) 47 knots (54 mph)
959mb 95° (from the E) 157 knots (181 mph)
957mb 95° (from the E) 146 knots (168 mph)
954mb 105° (from the ESE) 51 knots (59 mph)
951mb 125° (from the SE) 24 knots (28 mph)
The raw data is consistant with the decoded data. This was from an earlier flight this morning that returned to base before completeing the mission.
Raw data:
