SCIENTIFIC BALLOON ASCENSIONS VON BEZOLD

short intervals of time and which are here represented only by 

 this final outcome. 



These two latter tables 5a and $b have been especially introduced 

 because from them and especially from the data by altitudes in 

 table 56 we see clearly how rapidly the quantities of heat inter- 

 changed in given strata, diminish with altitude. 



Hence the influence of the highest strata on the economy of heat 

 in the atmosphere is of subordinate importance even when the 

 annual range of temperature is larger than we formerly suspected. 

 Even when ranges at great altitudes are as large as they are at the 

 ground still the quantities of heat exchanged in strata of equal thick- 

 ness are proportional only to the density of the air present therein. 

 This is another reason why it is not recommended to speak of the 

 heat of the air (luftwarme) instead of the temperature of the air. 



Now that we have thus illustrated the vertical distribution of the 

 meteorological elements from very various points of view, there still 

 remains the important question to what extent the results attained 

 by these ascensions are appropriate to remove the doubt that exists as 

 to the interchange of air between the cyclone and anticyclone or as to 

 the ultimate origin of these two groups of atmospheric whirl-winds. 



It follows from the memoir of Berson 14 that this important ques- 

 tion cannot yet be finally answered even from the results of balloon 

 voyages. But in order that we may at least approach the problem 

 somewhat more nearly I have requested Berson to prepare for me a 

 new analysis of the results with reference to the temperatures in the 

 cyclones and anticyclones for the summer and winter half years 

 separately. I submit this as table 6 but include in brackets those 

 numbers that result from one voyage only.
