Sometimes a reference point helps when evaluating a string of data. Looking at this map below of Global Flooding Hazard Frequency, it is obvious that
areas like Australia, are indeed experiencing abnormal events.
Comparing this map to any data sets showing historic flooding, just 'might' show certain trends that could help with pinpointing areas that deserve
additional research. It is obvious by looking at this map, that the MSM reports from Brasil were showing last week, actually occur in any area that
is at risk. However, the volume of water that inudated that region, was abornmal. Hence, a more indepth analysis might still reveal some supporting
"Global Flood Hazard Frequency and Distribution is a 2.5 by 2.5 minute grid derived from a global listing of extreme flood events between 1985 and
2003 (poor or missing data in the early/mid 1990s) compiled by Dartmouth Flood Observatory and georeferenced to the nearest degree. The resultant
flood frequency grid was then classified into 10 classes of approximately equal number of grid cells. The greater the grid cell value in the final
data set, the higher the relative frequency of flood occurrence. The dataset is a result of the collaboration among the Center for Hazards and Risk
Research (CHRR) , and the Columbia University Center for International Earth Science Information Network (CIESIN)."
And remember...knowing is half the battle!
