AUSTRALIAN WEATHER. 



The passage of this anticyclone was an unusually rapid one, 

 and is presented as portraying with a minimum number of charts 

 the easterly motion of anticyclones over Australia. 



TYPE II. MONSOONAL RAIN STORM. 



This type is undoubtedly the chief rain agent in the Australian 

 Continent. Monsoonal depressions or tongues may occur at any 

 time of the year, but particularly between the months of September 

 and April, and most frequently during January, February and 

 March. The readings of barometers in the depression seldom fall 

 very low, the grade from the surrounding areas to the centre of 

 the tongue ranging from one to three-tenths of an inch generally; 

 the depression may intensify, that is the tongues between high 

 pressures may protrude further south anywhere during their passage 

 across Australia, but show a preference to do so after they have 

 crossed central Australia, a fact which suggests that the heated 

 interior has at least some influence in their development. 



When and wherever the tongue is well defined, rain certainly 

 follows in its track, and thunderstorms as a wide spread and 

 simultaneous feature are never experienced without it.
