Weather Conditions during November, 1907. 



A. NOBLE, 

 Meteorological Department, Sydney Observatory. 



Ox the 1st and 2)i(l of the month li^ht rain was recorded, ehietly on the 

 coast; hut on the ;!rd one of the host rainstorms experienced for many 

 months passed over our State. All stations in the extreme north-west and 

 on the extreme north coast participated. The storm, whicli was responsible 

 for the above useful rainfall, was undoubtedly monsoonal in origin, and 

 developed rapidly. It resulted from the continued agency of monsoonal 

 conditions, operating over Northern Territory on the 1st, and the eastward 

 progression of a so-called Antarctic Depression passing along the shores of 

 the Great Bight. Some of the heaviest falls were: — Kiandra, 336 points; 

 Molong, 334; Junee, 330; Orange, 315; Carcoar, 311; Tuml)arumba, 309; 

 Wellington, 251; Young, 258; Mudgee, 270; Murrurundi. 218; Adelong, 

 215; Burrowa and Cowra, each 218; Rockley, 229; Bathurst, 210; Diibbo, 

 211; and Cannonbar, 208. 



During the period between the 5th and 13th, inclusive, light to moderate 

 rainfall of a partial character was recorded, chiefly over the south-east quad- 

 rant. Central Tablelands, and North Coast districts. 



Thence, to the 16th, light to motlerate falls were registered generally east 

 from the Western Division, and in parts of the North Coast district upwards 

 of an inch was received, the heaviest being: Manning Heads, 225 points; 

 Woolgoolga, 132; Seal Rocks, 130; Clarence Heads, 112; and Byron Bay, 

 103 points. 



As the result of the operations of a w^ell-defined monsoonal disturbance, 

 which intensified on the 16th and 17th, light to heavy and general rain fell 

 throughout the State. This disturbance, before it left our coast, was also 

 responsible on the whole for almost continuous rainfall over the various 

 districts of New South Wales east from the Darling. The heaviest falls 

 during the rainstorm, which lasted from the 16th to the 22nd, were as 

 follow : — Byron Bay, 444 points ; Armidale, 333 ; Murriu-undi, 315 ; Glen 

 Lines, 306; Bundarra, 294; Yetman, 282; Emmaville, 276; Mullumbimby, 

 263; Inverell, 257; Tabulam, 250; Grafton, 228; Walcha, 222; and Manning 

 River Heads, 196 points. 



From the 23rd to the 27th, rainfall, associated with thunder and hail, was 

 recorded over the Metropolitan, Hunter and Manning, Northern Tablelands. 

 North-western Slopes and Plains, as also at isolated places on the North and 

 South Coasts and Central Tablelands. Upwards of an inch in the aggregate
