SINCE Western Australia established in 1887 a number of new 

 Meteorological Stations, it has been possible to make our Weather 

 Charts more complete and to trace the progress of meteorological 

 conditions more minutely : and the opportunity has not been lost. 

 Some of the results are of purely local value as aids in forecasting. 

 Others seem to have more general significance, and will, I think, 

 be of interest to the Fellows of this Society and to meteorologists 

 generally, because they have an important bearing upon accepted 

 theories in explanation of " weather " in latitude 20 to 50 South. 

 So much so that I think it will be necessary to modify those 

 theories. There can be no doubt that the great extent of ocean, 

 as compared with the land, in the latitudes named, affords to 

 atmospheric circulation a field in which it may approach what it 

 would be, if the earth were completely covered by water, and the 

 atmosphere therefore free from the disturbing influences of 

 unequal heating, surface land friction, and mountains. 



The leading fact that our 1 investigations have brought to light 

 is that Australian weather south of 20 South latitude is the 

 product of a series of rapidly moving anticyclones, which follow 

 one another with remarkable regularity and are the great 

 controlling force in determining local weather. 



1 In the investigations which lead up to the results detailed in this 

 paper I have been very ably assisted by Mr. H. A. Hunt, who prepares 

 the daily Weather Chart, and who has carried out many investigations 

 to the successful discovery of weather laws here.
