Duriiii; llir wc.k cikIciI tlic ■J.'Jnl, Iwn aiii ic\'rluiics and one antai'ctic 

 flistiirbaiice passed ovrr Australia. The aiit i(\ rlones wci'e iinincnsc juvssure 

 systems. Approachiiijif tlie continent at about (ieraldton. <ni tlic coast of 

 West Australia, thcv "fraduallv extended tlieir inHuence eastward until all 

 the mainland and the Tasnian Sea between IS'ew Zealand and the coast 

 Of New South AN'ales anrl covered by their isobars. Where these latter con- 

 trolled winds, from the surrounding ocean to the seaboard showery teiideneies 

 obtained, but for the most jiail tine weatliei- luled o\ei- the interior 

 districts of the continent. Conditions were cold and fiosty, generally over 

 the southei-n parts of Australia during the week, excepting fi-om the 17th t > 

 to 19th, when, owing to the peculiar distribution of atmospheric pressure 

 over the eastern States, and the resultant winds, some high temjjerature.s for 

 July occurred over various districts. 



The highest temperatures reeoi-ded in eacli of the subdi\isions were: — 

 "VVestern Division, 7<'^ degrees at Mungindi ; North-western Plains, 7!' de- 

 grees at Pilliga : Central-westei-n Plains, 74 degrees at Carinda, (.^)uand)one. 

 and Coonarable ; Kiverina, 6S degrees at Cudgellico ; North-western Slojie, 

 7o degrees at Narrabri ; Central-western Slope, 67 degrees at Coonabara- 

 bran and Wellington; South-western Slope, 67 degrees at Grenfell; Northern 

 Tablelands, 74 degrees at Tabulam ; Central Tableland, ()7 degrees at Cowra: 

 Southern Tableland, 6-3 degrees at Braidwood : North Coast, ."^O degr-ees at 

 Grafton and Kempsey : Huntei- and Manning, 79 degrees at iNlainiing Heads: 

 Metropolitan, 78 degrees at Parramatta ; South Coast, HO degrees at Bodalla. 



Between the l8th and the 21st strong northerly winds, with rough to high 

 seas, and some good rainfall associated with hail, resulted from the antarctic 

 disturbance, more especiallv over the southern parts of the continent. In 

 West Australia, Perth had lol' points, Katanning 84, and Geraldton 76; 

 on the Queensland coast, Townsville had 1-50 and Cairns Til points ; in New- 

 South Wales light to heavy falls were recorded in the south-eastern (piadrant 

 and on the extreme North Coast. Kiandra had 14'-' points, Young 117. 

 Adelong 98, Tnmut 96, Tarcutta 9-3, and Burrowa 7S ])oints. 



During the last week of the month, an energetic and extensi\e anticyclone 

 •controlled, for the mo.st part, the weather of Australia. This high pressure 

 system, which is remarkable for its longevity, first appeared in West 

 Australia on the 20tli, and thence i-apidly extended eastward until it covered 

 the whole continent on the 22nd. Since this latter date the isolmrs were so 

 ari'anged (horizontally) as to govern fresh to sti'ong south west to south-east 

 winds along the seaboard and east and north-east inland. Not only was 

 this jiressui'e disti'ibution fa\ onralile to the transportation inland of winds 

 laden with moisture, but the many depressions around the isobarsof the anti 

 cyclone were res])onsible also for the accunudation of moisture oxci- many 

 ])arts of New South Wales and the other States. 



One series of these depressions in the isobars was show n on oui- central 

 coastal districts, and assisted in the remarkable rainstorm between July 27th, 

 and August 10th inclusive, during wliicli so inan\- liea\y falls were experi- 

 ■eneed in the metropolitan area and its outskirts. The winds on the coast.
