Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in figure 1, the typhoon automation forecast platform based on the global lattice point forecast data of EC/JMA includes three submodules
Block:Typhoon Route Forecast module, intensity of typhoon forecast module, Landed Typhoon point forecast module.
Typhoon Route Forecast module, including the real-time accesses of data, boiling pot judge, center maximum wind velocity is sentenced
It is disconnected, and product generation and issue.Choose the full Wind Datas of 850hpa(In dimensional wind data in meteorological research generally
One of height layer data, corresponding sea level on the average is about 1500 meters), it is daily to pinpoint from meteorological observatory's download.Will
The data downloaded carry out cyclone center's judgement.The cyclone in the Northern Hemisphere has the characteristics of wind field counterclockwise, circulation structure are closed.Reason
The wind field for thinking cyclone is symmetrical, and the transmeridional wind direction in center is respectively south east south wind and north/northeaster, north-south difference
For west/northwester and east/southeaster, generally the yardstick of cyclone is smaller, and central pressure is lower, and intensity is stronger, wind field knot
Structure more meets ideal conditions(Fig. 2).According to cyclone feature, synchronization may find out multiple cyclone centers, it is necessary to by judging
The wind field structure and circulation strength of all cyclones, remove the cyclone center for the condition that is unsatisfactory for.The cyclone center finally retained, is carried out
Polar coordinates interpolation, obtains paracentral maximum wind velocity.According to the data frequency received, corresponding typhoon track product is generated simultaneously
Issue.
Intensity of typhoon forecast module, including polar coordinates interpolation, solar or lunar halo grade determine, and product generation and issue.Will

Landed Typhoon point module, includes the acquisition of coastline data, and coastline Distance Judgment, debarkation point time judge, with
And the generation and issue of product.The typhoon track product of generation and coastline data are subjected to Distance Judgment, retained and coastline
Intersection point, reject and be unsatisfactory for logging in the point of condition.The point around debarkation point in the range of 0.5 longitude and latitude is taken as debarkation point, and
Determine the landing time scope of debarkation point.
In order to finally give the product of the typhoon automation forecast based on EC/JMA data, operational use, this hair are put into
Three modules are forecast in bright Typhoon Route Forecast, intensity of typhoon forecast, and the debarkation point of being integrated with, and ultimately generate typhoon automation pre-
Report product.
The forecast step of a module is described below
1st, Typhoon Route Forecast step
EC/JMA material forms are 2-D data(X/Y), wherein EC data lattice point is 145*37, and JMA data is 113*73,
Deposited in micaps forms.EC data temporal resolution be 24h once, JMA data temporal resolution is first 48 hours every 6 small
Shi Yici and every 12 hours latter 36 hours are once.Data is read for convenience, and this method uses F90 programmings.For wind field
Each lattice point of data, carries out following calculate:
1), determine generation area.For tropical cyclone of northwestern Pacific Ocean multi-activity in the LOWER TROPOSPHERE of low latitudes, therefore
Data scope is limited in the range of 0 ~ 50 ° of N, 100 ~ 180 ° of E.EC Grid datas used are at intervals of 2.5 longitudes and latitudes, JMA lattice
Point data break is 1.25 longitudes and latitudes.
2), find out all cyclone centers engraved during each forecast.As shown in Figure 3, it is assumed that each lattice point center is meter
Calculate regional center(Cyclone center), using the lattice point of the angle point of central point 4 as " circle ", carry out judging 2 ~ 3 circles from inside to outside, with center
4 adjacent lattice points of point are first lap, and continuous 4 points meet preferable cyclonic circulation condition, then the point is cyclone center, retains the point
For the judgement of boiling pot.
Weaker at the formation initial stage of tropical cyclone and latter stage circulation yardstick, wind field structure is often asymmetric, and center wind field has
When it is more chaotic, to avoid yardstick from meeting condition and the weaker cyclone of circulation, it is ensured that first retain these cyclone centers, then pass through
Several steps judge progressively to reject the cyclone center for the condition that is unsatisfactory for below.For weaker cyclone, above method can often be judged many
Individual cyclone center's point(Possible two neighboring lattice point is satisfied by conditions above), therefore also need to further correct.Correction method is
Record the starting solar or lunar halo for meeting condition of each cyclone center's point, the starting solar or lunar halo of which cyclone center's point near center,
Then retain cyclone center's point, remaining cyclone center's point is removed.For example adjacent 2 points, the circle of point 1 the 3rd is the starting wind for the condition that meets
Circle, the circle of point 2 the 2nd is the starting solar or lunar halo for the condition that meets, then retention point 2 removes point 1.The foundation so judged is closest in cyclone
The heart, its wind field cyclonic circulation feature is more notable(Fig. 4).If obvious double division centers occurs in cyclone, Liang Ge cyclone centers are judged
Whether point is distant, and such as Liang Ge cyclone centers point distance, if exceeding, meets condition same whether more than more than 5 lattice points
When retain Liang Ge cyclone centers point, judge the situation of binary typhoons occur.
3), centering point maximum wind velocity value.Boiling pot maximum wind velocity, carries out polar coordinates by cyclone center's point and inserts
Value, specific practice is first in the range of the cyclone center outside 500km of point, to obtain the warp that natural coordinates is converted under polar coordinates
The offset of broadwise, the accumulation amount of offset latitude and longitude value corresponding with central point is the longitude and latitude size under polar coordinates.Correspondence
Polar coordinates air speed value, completed by polar coordinates interpolation algorithm, such as by corresponding wind speed on 37*145 lattice point of EC Forecast Modes,
Be converted to the wind speed size under correspondence polar coordinates longitude and latitude.Maximum wind velocity is the cyclone center that we require on polar coordinates after interpolation
Maximum wind velocity value.
4), judge complete typhoon track.As shown in figure 5, a complete Typhoon Route Forecast, is by continuous several
What cyclone center's point of forecasting period was judged, if cyclone center's point of two neighboring period is closer to the distance, meet same
The distance range of bar typhoon, it is the point on same paths to give tacit consent to this 2 cyclone center's points.For example whether distance is in 5 lattice points
Within, if judging to enclose same typhoon in 5 lattice points, more than more than 5 lattice points if in reservation two simultaneously if meeting condition
Heart point, judges to be likely to occur the situation of binary typhoons.
Opposite 2 cyclone centers point is distant, then it is the point in Article 2 typhoon track to give tacit consent to one of point.If
In this forecasting process, the point is an isolated moment point, then excludes the possibility of the paths.Sentenced by the distance of cyclone center's point
It is disconnected, a fullpath at forecast moment is obtained, and distinguished the influence of binary typhoons.
2. intensity of typhoon is forecast
1), determine cyclone center's point solar or lunar halo grade.As shown in fig. 6, the cyclone center's point wind speed found out for the above method
Polar coordinates interpolation of carry out of value, that is, obtain around the central point solar or lunar halo size in the range of 500km.
3. debarkation point is forecast
1), coastline data choose.Whether the development in order to judge typhoon has an impact to inland, it is necessary to be directed to typhoon track
The path product of module generation, judges to forecast whether path logs in coastline, and debarkation point time etc..The coastline of selection
Data scope is 5 ~ 45 ° of N, and 100 ~ 125 ° of E, data used include the latitude and longitude information file in coastline, and land and ocean
Significant lattice point file(0 is ocean, and 1 is land).
2)Debarkation point judges.Distance Judgment will be carried out between each cyclone center's point and coastline point first, if distance
Less than or equal to 0.2 longitude and latitude, then it is assumed that cyclone center's point may be login point.Then the significant of land and ocean is passed through
File, judges the flag states 1/0 around cyclone center's point, that is to say, that if before cyclone center's point be 0, behind be
1, then it may determine that the point is logged in.2 cyclone center's points set up linear equation before and after path cyclone center's point will be forecast, if
There is intersection point with coastline between 2 cyclone center's points, then judge the intersection point for debarkation point, take one closest to land point
Intersection point is debarkation point.The coastline point around debarkation point in the range of 0.5 longitude and latitude is obtained as logging zone scope(Fig. 7, ash
Color region is registered scope).Then by judging that the debarkation point accounts for the distance between 2 cyclone center's points ratio, it is determined that logging in
The time range of point.
