Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] A method for extracting objective typhoon forecast information from numerical forecast products proposed by the present invention, its overall realization block diagram is as follows figure 1 shown, which includes the following steps:
[0034] ① Determine a typhoon origin field and several corresponding typhoon forecast fields in the numerical forecast product, and use the location of the typhoon center announced by the Central Meteorological Observatory at the same time as the typhoon origin field as the typhoon center location of the typhoon origin field Location.
[0035] In the numerical forecast product, various meteorological elements at a certain moment are used as the initial field, and the forecast time limit at that moment is 0 hours. Based on this moment, according to the atmospheric motion equation, the atmospheric conditio...
