These are 2 of the classic winter storm tracks that are discussed on the board. A Miller A storm has a primary storm, with no secondary development, that rides up along the coast or spine of the Appalachians typically. The March 1993 Super Bomb was just one of these.

A Miller B has a primary storm track that comes out or Alberta, Canada that spawns a secondary storm along the east coast from the Carolina's all the way up the coast. The January 2005 Bli
It's actually not a transfer of energy. That terminology is incorrectly used many times. What happens is that the primary low is becoming more vertically stacked, and thus losing upper level support (differential vorticity and temperature advections). The best upper level dynamics are now out ahead of the primary low, and as it reaches the coast where a natural baroclinic zone is present between the warm ocean and cold land, a secondary low develops.
