Fic. 6. The N-S alignment of the Pc cold 
front results when cold air passes rapidly 
south to the Gulf while the tropical air is not 
displaced eastward very far. A _ wave-dis- 
turbance has started in the southeast and an

with the Tm air spreading westward aloft 
over the Pc causing very heavy snow and 
N-ly gales in New England. (Legend for this
