TYPE XVII.—SUMMER ANTICYCLONES. 
One of the most marked features of weather in Australiais the 
‘regular easterly motion of it in all seasons of the year, addedt? 
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.’ The 
summer latitude is about 40° south. They are less extensive in 
summer than in winter, and do not so completely control out 
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.

During the winter months the antiyclones are much large ot 
they are in summer, and their latitude about 30° 8.; vey ere 
monly their area is equal to Australia, and their control of the 
weather more complete than it is in summer. Fine wea
