The pansystems view of prediction and blow-up of fluid

From the pansystems view of prediction, the paper investigates the blow-up and post blow-up of fluid in rotation and convergence. The results show that the motion includes certain characteristics of reverse transformation the counter clockwise rotation can be developed into clockwise, and vice versa; the convergence can be changed into divergence through blow-up, and the divergence will die out continuously. The real forecasting must look this mechanism in the face. Generally speaking, the forecasting of evolution for fluid can't be considered only as traditional Cauchy problem. The traditional forecasi models should be rediscussed questioningly.
