John:
I have (and I have now found) a "Forest Fire Danger Meter" designed by A G
McArthur of the Forest Research Institute, Forestry & Timber Bureau,
Canberra - given to me by him when I visited and enjoyed a fascinating
conversation on a subject I knew/know little about - now quite a while ago.
It is made of four circular cards pinned in the centre to revolve on a
fifth square card at the back. Cards represent rainfall & days since rain:
to give "drought factor"; and relative humidity, air temperature, and
finally the "danger index". On the back there is additional information
about fire behaviour in various winds and forest types.
Now something of an antique, I would be loath to part with it, and of
course it preceded other more easily transmittable forms. Maybe there are
Australian sources for the current-day version ?
With additional meteorological information, it might be adaptable for
storms, cyclones, and floods of various sorts.
The connecting splt-pin is removable, each card then being copyable and
postable, to which I would be amenable, and then it would be remountable.
This, I am sure, is not quite the sort of thing you are looking for - but
let me know.
