AUSTRALIAN WEATHEK. 



TYPK XVII. SUMMER ANTICYCLONES. 



One of the most marked features of weather in Australia is the 

 regular easterly motion of it in all seasons of the year, added to 

 this the anticyclones the controlling element in our weather 

 change with the sun, so that the latitude they follow in their 

 easterly progress is further south in summer than in winter. 1 .The 

 summer latitude is about 40 south. They are less extensive in 

 summer than in winter, and do not so completely control our 

 weather as they do in winter, for their southern position leaves 

 room for the southerly extension of monsoonal low pressures, 

 which make a great deal of our weather ; but the anticyclone 

 makes the change from hot northerly to cool southerly winds, the 

 bursters of the east coast.

TYPE XVIII. WINTER ANTICYCLONES. 



During the winter months the antiyclones are much larger than 

 they are in summer, and their latitude about 30 S.; very com- 

 monly their area is equal to Australia, and their control of the 

 weather more complete than it is in summer. Fine weather
