31. High wind shear also allowed for intense rotation in the atmosphere. 32. Low wind shear allowed the convection to sustain around the eyewall. 33. Pilots had reported wind shear in the area before the incident. 34. Rapidly shifting winds called wind shear can be a pilot's nightmare. 35. The second mechanism involves wind shear forces on the water surface. 36. Low-level turbulence over California could lead to dangerous wind shears in canyons and passes. 37. The wind shear keeps spiking the helicopter downward and making its tail slew about. 38. The storm continued to weakening due to strong wind shear . 39. When wind shear occurs, a sudden gust of air initially pushes the aircraft forward. 40. The airborne instruments will complement ground-based wind shear detection systems at most major airports.
