Embodiment Construction
[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0052] figure 1 A flow chart of a radionuclide accident atmospheric diffusion trajectory set prediction calculation method in a specific embodiment of the present invention is provided, and the method mainly includes the following steps:
[0053] (1) Calculation of wind field drive data set ;
[0054] The wind farm drive data set described in this step , in this embodiment, it is first necessary to perform statistical analysis on the historical meteorological data to obtain the three-dimensional joint frequency table of the annual wind speed and direction stability, and then use the random sampling function to randomly sample the three-dimensional joint frequency table of the wind speed and direction stability for at least 5000 times to obtain the wind speed and direction stability. Field-driven data collection. In addition, aft...
