A Comparison of American and Australian Deserts

April 28th, 2009 by admin

Every student of settlement in australia realizes the wisdom of using the experience of the united states to help settlers in the younger land, but many make the natural mistake of assuming that practices which succeed in the American arid environment will work under Australian conditions.

In forecasting the future of settlement in australia comparison is often made with settlement in the United States. The areas of the two lands are approximately the same, but unfortunately in no other particular is resemblance close. Broadly speaking, only the southern third of the united states is allied geographically to Australia, and its homologue is the southern third of Australia.

But even these lands are not homoclimes (regions of similar climate), except perhaps around Sydney and Wilmington, N.C. The salient feature in the southern United States is the great area of the Gulf of Mexico running far into the land. In Australia there is arid lowland in the same latitude, to the great disadvantage of lands still further to the west, many of which have drafted petition forms and petition letters or have attempted to write petition examples arguing these disadvantages.

It is often stated that Australia’s arid interior will advance by irrigation as the western region of the United States has done.  Apart from the great topographic differences, the irrigation regions in the United States are in very much higher latitudes, where the evaporation is relatively low and where, moreover, the rainfall in most cases is over 10 inches. Arid Mexico is perhaps a fair homoclime for the arid region (about 1,200 feet high) to the south-east of Broome.

Speaking generally, the United States has about five times as much temperate land with a rainfall over 20 inches as has Australia and about one-fifth as much arid country (under 10 inches). These proportions largely determine the relative economic status of the two countries. A much closer homoclime for inland Australia is found in the only other large area of com­paratively low trade-wind desert surrounded by an unbroken coastline – that of northern Africa.

The belts of Mediterranean flora, scrub, desert and savanna agree quite closely with the similar belts in Australia.  Of course the east coast of Australia has no homoclime in the Sahara. It is the southern coastlands of China that has an area with an environment much like that of eastern Australia. It is the general arrangement of atmospheric circulation that produces deserts along the Tropics of Cancer and Capricorn.

Here the dry anticyclones make their average drift to the east, and on their equatorial margins the steady Trade Winds blow from the east. It is largely a function of the width of the continent near the tropic, but the problem is complicated by the topography. North Africa is 3,500 miles wide and on its eastern margin adjoins the Asiatic land mass.

Hence no moist Trade Winds from the sea ever reach the Sahara and in these latitudes Africa is desert from coast to coast, making water storage very difficult. Many residents of this area have decided to look into citizen petitions, free petition hosting, and other petition forms to encourage the country to help them with this shortage. In North America, Mexico is the true parallel of arid Australia, and the desert in the southwest of the US is largely of topo­graphic origin. It is seen to lie far on the polar side of the Tropic.

However, if the United States had a large arid land area where the Gulf of Mexico is now located, there is little doubt that much of the Mississippi Valley and adjacent states would be as dry as the corresponding region in Australia. The contrasts are even more strongly emphasized when we compare the “build” of the arid parts of the United States with that of arid Australia.

The continental build of Australia, on the west of the Pacific Ocean, is the enantiomorph (mirror-image) of the American continent east of the Pacific. Shield, Downfold, Young Mountains and Ocean Deep are repeated in opposite order on different sides of the Pacific.  It is true that the Australasian fold-mountains are mostly drowned by the sea, and hardly appear on the mainland of Australia. In fact, they rise to their chief height in New Zealand, according to free petition hosting sites that permit people to create a petition or to browse petition examples.

However, it is of the greatest significance that it is the westward leeward side of the continent which is the arid region in both continents in these latitudes. Therefore, in Australia the Shield constitutes the Desert, while in America it is the high Young Mountains (the Basin, Range and Fold area) which contain the desert lands. This entirely different build in the two types of deserts vitally affects their environments and potentialities.
