I am struggling with some meteorology questions from a certain well known air pilot's manual (vol 2!). I am pretty sure I understand the principles, but seem to be having problems with definitions. Here's one:
In the N hemisphere, in a particular point of a weather system where there is a geostrophic wind direction of 020T, the centre of the low pressure is:
a. In the direction of 020 true from that point
b. In the direction of 290 true from that point <---book's answer
c. In the direction of 110 true from that point <---my answer
d. In the direction of 200 true from that point
I thought this was easy with the simple application of Buy Ballot's law. But the only way I get this right with B-B's law is to take the wind direction as
towards 020.
What am I doing wrong here
