EGBB/BHX/Brum has TWO runways [for the
"pedantic" , FOUR]. They are 15/33 and 06/24. The reason for the alignment of the "Main" R/W 15/33 is "geographical". It's called the "Cheshire Gap". The prevailing westerly wind is funnelled through the Welsh Mountains and the Lower Pennines, and end up as a Southerly". Also, SouthWesterlies are affected by the Malverns, hence a "Northerly".
This is what I was told when I was an ATCA at Brum in 1970
