TYPES OF AUSTRALIAN WEATHER. 513 
TYPES OF AUSTRALIAN WEATHER. 
By Henry A. Hunt, ; 
Second Meteorological Assistant, Sydney Observatory. 
[With Forty Diagrams. ] 
Iv continuation of the valuable work on Australian Meteorology 
which the Hon. Ralph Abercromby initiated several years since, 
by offering a money prize for the best essay on Southerly Bursters; 
he has recently selected the phases of Australian Weather which 
are treated in the following twenty studies of “ Types of Austra- 
lian Weather,” Many of these appear to be peculiar to Australia, 
and at the same time connected with Equatorial and other weather. 
That they throw much new light upon the source of the greater 
part of Australian rain, and show how these rain storms develop 
out of ordinary weather conditions is certain ; at the same time 
they form an important contribution to the study of weather in 
the Southern Hemisphere generally. The work has been done 
by Mr. H. A. Hunt, at Mr. Abercromby’s expense, and Mr. 
H. ©. Russell, has edited the work. 
GENERAL REMARKS. 
As a general rule, weather is set fine when anticyclones move 
tapidly, and in a straight line across Australia, 7.¢., at a rate 
exceeding five hundred miles per day. And weather is unsettled 
= they move slowly, and not in a straight line, 7.¢., in a zigzag 
>a *specially if they show no appreciable forward motion for a 
day ortwo. When anticyclones move in low latitudes the con- 
— favour dry weather, in high latitudes, wet weather, 
specially it they rest for a time south of South Australia. 
aang examples of weather phases which follow have been 
rom the Sydney Weather Charts, and illustrate each 
Bs : a originals were carefully traced, and then reduced from 
‘‘ to the size used in this essay by means of the camera.
