Lake Eyre is amazed by it’s mystery. To be “disappeared” every three years, meanwhile, to be encountered the flood every decade are its consistent style. For those visitors,the style of shift from full to “disappear” introduces completely different experiences every single year. What causes the shift? And how we can perform this shift through mapping? Firstly, the intuition reason of the shift is the changes in rainfall. And secondly, rom meteorology point of view, this ghosty behavior is mostly based on the shift between the effect of La Nina and El Nino which make the world extremely cold and warm. Obviously the shift between the two climate phenomenas create the performance of Lake Eyre.
Mapping the relationship between the rainfall tendency and the perform of La Nina and El Nino help understanding the shift. The line technique of Maya Lin’s wire models( systematic landscapes and above and below) inspired the initial idea of represent the tendency; and the drawing precedent of James Corner contribute the technique of using density of lines to performance strong or weak.
Lake Eyre is amazed by it’s mystery performance. As a seasonal lake, its area or boundary is influenced strongly by rainfall which is the mainly climate phenomenon of La Nina. So that it is not difficult to understand the fluctuation boundary of Lake Eyre. And the shape of every curves depends on the flow and erosion speed of every year.
By mapping those boundaries, the data of rainfall is the basement to determine the approximate shape, the channel form and the flow form the specific shape.
The species invited in the lake is Australian Pelican. This kind of bird prefer large expanses of open water without too much aquatic vegetation, care less about the surrounding environment, and value the supply of sufficient fish. They usually stay at coast around Australia, but when lake eyre is flood, there will be almost no pelican around the coastal area. So this behaviour can be summarised the number of pelican depends on the size of water in Lake Eyre.
