of any great importance as a factor at large in local climatic variations. 
In a rough-and-ready way, as between one station and another, it is 
perhaps correct to say that where the variability is greatest there will 
the force of the wind be the greatest and the storms most intense. But 
at any one station, say Kimberley, greater or less monthly mean varia- 
bility does not, apparently, mean more or less wind during the month, nor 
higher or lower temperatures, nor greater or less range of temperature, 
nor more or less rain or clouds or sunshine. To a certain extent this 
result might have been anticipated. For as the barometer oscillates on 
one side or the other of the mean, so does the wind, and the cloud, and 
the temperature. A fall in the barometer means an increase in the velocity 
of the wind and a rise of temperature ; while a higher barometer, to begin 
with, goes with light winds and low temperatures. These, however, are 
weather factors — factors, that is to say, of what Professor E. de C. Ward 
calls cyclonic control," and are not, strictly speaking, factors of climate.
