The results show that this method can reveal important changes of weather as well as, by using irregular self-recording information recorded every ten minutes, predict local thunderstorms with durations of only half an hour, and even predict intense convections 12 hours in advance. This is significant for civil and military aviation. It shows the necessity of full utilization of information from automatic weather stations and the necessity of improvements in recording modes in current automatic stations.展开更多

And a successful simulation of Tang Shan Earthquake in 1976 has been given. The result of simulation indicates that the blown-up of ground temperature 'flow' around earthquake can be applied to predict earthquake. As for Tang Shan Earthquake, the predicting time is about five months. If ground temperature 'flow' that embodies the earth's crust satisfies the unintegral panderivative equation, we can demonstrate its mechanism and forecast earthquake with enough information.展开更多

The blown-up of Navier-Stokes equation is discussed in references [1, 2]. Some expansion is made in this paper, and the blown-up of order-1 or 2 models and the 'rebel travelling' of complex model of poly-order are discussed. The results indicate that 'semi-rupture' appears for some models on specific condition: the blown-up appears during the whole evolution. For fluid, however, the weakly-nonlinear model is of more artificiality and there is much room for arguing about the smoothing scheme of the numerical integral on the basis of continuous thinking and so on.展开更多
