The definitive answer is that a cloud can deliver either a positive 
or a negative charge to earth. Lightning can go any direction but 
NASA has a good primer before we get caught up in definitions.

My best recording of thunder still is cliped but was made with a low 
sensitivity microphone that could handle a high volume and is in 
stereo. Good thunder recordings are a lot of work as well as luck.
