Meteorological Work in Australia: A Review (continued)

In all there are about eighty selected reporting stations, besides which nearly every telegraph station reports at 9h. a.m. to the head office the direction of the wind. the state of the weather, and the rainfall, which are also posted in a collective form at the General Post Office for public information.

From these data isobar and weather charts are compiled in nearly all the colonies, together with the forecasts to which I have referred.

At Adelaide, where, as I have already said, we have issued daily isobar maps since 1882, we exhibit a diagram showing the barometric curve it selected stations along the south coastline from Albany to Cape Howe during the month, which enables persons to see at a glance the westerly progressive march of coastal depressions; and we have recently added a map which shows the distribution of rain in the colony or each wet day.

We also publish monthly a statement of the rainfall at every Station throughout the colony. compared with the average of the corresponding month deduced from previous years, accompanied by a complete discussion of the characteristics of the month in regard to temperature, pressure, the passage of "highs" and lows," and the weather generally, in which companions are made between the month under review and previous seasons, attention being drawn to any abnormal features that may have presented themselves.

The annual volumes give in detail the observations at Adelaide, the principal results at outstations, and maps showing in graduated tints the general distribution of rainfall during the year.

An examination of the daily isobar maps extending over a period of eleven years shows that, while we have an infinite variety of details, there are several well-marked types which are frequently recurring.

No two maps of the same type, perhaps, may exactly agree or resemble each other, but the type to which they belong is at once recognised. We can thus classify our maps into their respective types.

I have selected seven well-marked types to accompany this paper (see Plate VI)
