Welcome to the CPL Meteorology question and answer forum. Please feel free to post your questions but more importantly also suggest answers for your forum colleagues. Bob himself or one of the other tutors will get to your question as soon as we can.
Got a COLlection of questions...not really just the one. Thought i'd ask it in here for clarification.
Q: Strong horizontal wind shear would most likely be encountered:
A. At a strong surface inversion boundary
B. within a decaying thunderstorm cell
C. Near a low-pressure system
D. In a cirrus cloud
Answer is A, although my reasoning leading me to pick B is that the question states for horizontal wind shear which is the change in wind speed/direction at the same level as opposed to vertical wind shear which is the change of wind direction/speed with height. To experience horizontal wind shear through a surface inversion boundary would mean the aircraft would be climbing through a surface inversion to experience windshear, meaning height was gained and wind speed/direction changed aka vertical windshear. Flying through a decaying thunderstorm cell would mean remaining at the same level while experiencing differing wind speeds through downdrafts aka horizontal windshear.
