70 INSTRUCTIONS TO MARINE METEOROLOGICAL OBSERVERS 



Stratocumulus. — A layer or patches composed of lamina, or globu- 

 lar masses; the smallest of the regularly arranged elements are fairly 

 large; they are soft and gray, with darker parts (fig. 21). 



These elements are arranged in groups, in lines, or in waves, 

 aligned in one or two directions. Very often the rolls are so close 

 that their edges join together (fig 22) ; wdien they cover the whole 

 sky, as on the continent, especially in winter, they have a wavy 

 appearance.
