Re:The truth about weather predicition (Score 2)

There is very little chance in the foreseeable future that weather predicition will be 100% correct, no matter how fast the computer get

Change that to no chance and I'd agree with you. It turns out that the fundimental equations of motion for the atmosphere are unsolvable. That means that computer models need to be based on equations that are already approximate. Further, models divide the atmosphere with a three dimensional grid. The finer the grid, the better the forecast, the faster the computer needed to run the model in a timely manner. But no matter how fast the computer, models will always have grids and will always be approximate. Then there will be rounding errors in the floating point calculations, approximations to prevent small anomolies from propigating through the model, and bad, incomplete and under-representative input. This stuff makes rocket science look easy.
