A wind of 225° blows ? Course > specific The jet stream is ? The jet stream A high speed air current at altitudes between 6 5 km. The arrow shows ? The arrow shows The position of a jet stream. When isobars are close together on a surface weather chart it means The position of a jet stream. The strong wind currents found at very high altitudes are called The position of a jet stream. A wind 090/20 comes from East at a speed of 2 kt. A wind 230/15 comes from Southwest at a speed of 5 kt. 8 A wind 180/10 comes from South at a speed of kt. 9 Which instrument used measuring wind speed on ground South at a speed of kt. 10 When pressure gradients are important over a short distance we can assume South at a speed of kt. 11 During a descent from 2 000 feet agl to surface you will usually find that wind South at a speed of kt. 12 The diurnal change of surface wind velocity such that during day surface wind will usually Veer increase in speed. 13 With passage of a cold front surface wind will usually Veer increase in speed. 14 When confronted with a thunderstorm take off or landing Should be avoided as a sudden wind shift or low level turbulence could cause a loss of control. 15 On a weather chart wind flows isobars above feet Should be avoided as a sudden wind shift or low level turbulence could cause a loss of control. 16 At night as a valley cools down air becomes denser and flows downward and referred to as Should be avoided as a sudden wind shift or low level turbulence could cause a loss of control. 17 Identify statement that accurate according to wind speed at altitude Winds are usually stronger at altitude. 18 The position of a wind indicator on an aerodrome a 6 kt wind Winds are usually stronger at altitude. 19 The position of a wind indicator on an aerodrome a 10 kt wind Winds are usually stronger at altitude. 20 The position of a wind indicator on an aerodrome a 15 kt wind or more Winds are usually stronger at altitude.
