MISCELLANEOUS STUDIES 



It appeals that the theoretical results agree well with observation. 

 If the difference between the theoretical and observed mean annual 

 temperatures due to the average departure of the local conditions 

 from the normal is applied as a correction to the observed monthly 

 temperatures the agreement between theory and observation is very 

 close. 



Numerical estimates of the coefficient of absorption of solar radiation 



in sea water. 



A lower limit of the value of the absorption coefficient b l can be 

 determined from quantities depending on surface temperatures and 

 the amount of solar radiation at the surface of the ocean by the fol- 

 lowing method. The value of K l (p. 344) obtained from Angot's data 

 (Hann, 1915, p. 40) was 



7f 1 = 5.18X 10 7 A 



where A is the solar constant. The more accurate result of Schmidt's 

 later investigation (1915; p. 121) (p. 345) is 



Since = 



K 1= = 217 X 30 X 10* = 3.255 X 10 7 A. 



Bm l = 5.9 (p. 347)

K 



But since is the ratio of the amount of energy supplied to the water 



v 

 by solar radiation to the amount available at the surface, -=- < 1. 



Therefore 



K = 5.54 X 10 6 = 5.54

Using the accepted value 2.00 for A we have 

 mjti = b^er^ > .0851.
