Embodiment 1
[0058] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings. In order to fully understand the technical solution of the present invention, the symbols and meanings involved in the technical solution of the present invention are described below:
[0059] 1 Symbols and Definitions
[0060] 1) t: time point of observation data, (t=1,2,...,n)
[0061] 2) j: the number of variables in the observed data, (j=1,...,m)
[0062] 3) MD: direction of movement
[0063] 4) MV: moving speed
[0064] 5) P: pressure
[0065] 6) Lo: longitude
[0066] 7) La: latitude
[0067] 8) G: Grade
[0068] 9) V: wind speed
[0069] 10) U: set of typhoon elements, U={F 1 , F 2 ,...,F m}
[0070] 11) μ: an abstract metric function
[0071] 12) L: Typhoon time series length
[0072] 13) Q AC : Integrity factor threshold
[0073] 14) Q AU : Consistency coefficient threshold
[0074] 15)V max : 1-minute av...
Embodiment 2
[0147] The present invention selects "201525" typhoon data as the reference typhoon data, and the number is 1; then selects "201526" typhoon data and "201527" typhoon data, and the numbers are respectively 2, 3, and the original data of No. 1 typhoon are as follows: figure 2 Shown:
[0148] According to the method proposed by the present invention, the restoration process is as follows (taking "No. 201525" typhoon as an example):
[0149]Through the query, the two elements that need to be repaired are the direction of movement and the speed of movement. The specific method is as follows:
[0150] (1) MOVE TO REPAIR. The direction of movement in the original typhoon data is recorded using the sixteen-wind direction map. In order to facilitate subsequent calculations, it needs to be expressed numerically. It is stipulated that north is 0, south is 8, and clockwise from north to south is 1-7; Counterclockwise from north to south is 9-15.
[0151] The angle is calculated acco...
