to the upper left. They indicate the rate of 

 temperature change in a parcel of air rising 

 or descending adiabatically. They are labeled 

 for each multiple of 10° C. (See figure 11-32.) 



4. SATURATION ADIABATS-These are the 

 slightly curved, solid green lines, sloping from 

 the lower right to the upper left. Each is labeled 

 with the Celsius temperature value of its point 

 of intersection with the 1000-mb isobar. (See 

 figure 11-33.) 



5. SATURATION MIXING- RATIO LINES-The 

 slightly curved, dashed green lines, sloping from 



the lower left to the upper right. Labeled in 

 parts of water vapor per 1000 parts of dry air 

 (grams/kilogram). (See figure 11-34.) 



Other data are printed on the diagram in-
