Question
In which of the locations mentioned below is the development of a surface cyclone most likely? (Assume this is in the Northern Hemisphere)
Along the axis of an upper level ridge.
Ahead of an upper level ridge axis, east of the ridge axis
Behind the axis of the upper level trough, west of the trough axis
Ahead of an upper level trough axis, east of the trough axis.
a.Along the axis of an upper level ridge.
b.Ahead of an upper level ridge axis, east of the ridge axis
c.Behind the axis of the upper level trough, west of the trough axis
d.Ahead of an upper level trough axis, east of the trough axis.
Explanation / Answer
when large air mass rotates around the low pressure zone is called cyclone . and trough is the low pressure zone. for westerlies , west trough axis become high pressure one and having convergent winds and east trough axis region becomes low pressure zone and having divergent winds and give birth to the tropical cyclone.
so the location where the development of a surface cyclone most likely is -
(D) Ahead of an upper level trough axis, east of the trough axis.
