TEMPERATURE CONDITIONS. 



Temperature is certaiiil}^ the most important of all the climatic ele- 

 ments since changes of temperature are the primary cause of all move- 

 ments in the atmosphere and of the condensation of moisture into clouds 

 and rain. Animals and plants are dependent for life on a range of 

 temperature within certain definite limits^, and even man is more or less 

 favorably or adversely affected in almost every occupation of life. The 

 most important facts in regard to temperature are most briefly expressed 

 by the monthly and annual means. These will be found in Table V'l. 

 The highest and lowest monthly means during the entire period of obser- 

 vations have been selected to show the possible variations from normal 

 conditions.
