Method Details

AutoMode1

public double[] AutoMode1(String ForecastFile,
 int ForecastFileType)
                   throws IOException

Determine storm position at time CurrentTime using NHC/JTWC forecast discussion products. Time and location information from these products are then interpolated to time in question to derive a estimated storm position. If position estimation cannot be calculated, a lat/lon position of -99.5/-999.5 will be returned. Inputs : None Outputs : Latitude_Return - estimated latitude position Longitude_Return - estimated longitude position PositioningMethodID_Return - method used to derive storm location Return : -43 : Error w/ forecast file open and BAD extrapolation -44 : Invalid forecast file and BAD extrapolation -45 : Error w/ forecast file read and BAD extrapolation -46 : Error w/ forecast interpolation and BAD extrapolation 42 : GOOD INTERPOLATION 43 : Error w/ forecast file open but GOOD EXTRAPOLATION 44 : Invalid forecast file but GOOD extrapolation 45 : Error w/ forecast file read but GOOD extrapolation 46 : Error w/ forecast interpolation but GOOD EXTRAPOLATION 0 : Subroutine Error

Throws:

IOException

AutoMode2

public static double[] AutoMode2(double InputLatitudePosition,
 double InputLongitudePosition)
                          throws IOException

Additional automatic positioning of storm center location using official forecasts from NHC or JTWC as input. Storm location will be estimated using spiral fitting and ring fitting routines derived by Tony Wimmers in his MatLab routines (which have been converted). The final position will be determined utilizing empirically defined confidence factors for each method. The final storm position will be returned along with a position determination flag.

Parameters:

InputLatitudePosition - Storm center latitude.

InputLongitudePosition - Storm center longitude. Outputs : Latitude_Return - final storm center latitude position Longitude_Return - final storm center longitude position PositioningMethodID_Return - method used to derive storm location 0-error 1-interpolation of operational forecast 2-Laplacian analysis (not used anymore) 3-Warm Spot location 4-10^ log spiral analysis 5-Combo method of spiral and ring analyses 6-linear extrapolation from prior locations Return : Error flag = 0

private static double[] CalcScores(double FirstGuessLatitude,
 double FirstGuessLongitude,
 double SpiralCenterLatitude,
 double SpiralCenterLongitude,
 double SpiralCenterScoreValue,
 double RingFitLatitude,
 double RingFitLongitude,
 double RingFitScoreValue)

This routine will determine the confidence scores for the spiral fitting and ring fitting routines and calculate the best possible position for the storm center based upon a combination of the two methods, if available. If the ring fitting routine does not determine a good candidate position, the spiral fitting routine will be used alone. If the spiral fitting routine candidate point is not "good", the forecast point will be selected.

Parameters:

FirstGuessLatitude - First Guess latitude.

FirstGuessLongitude - First Guess longitude.

SpiralCenterLatitude - Spiral Analysis latitude at max location.

SpiralCenterLongitude - Spiral Analysis longitude at max location.

SpiralCenterScoreValue - Spiral Analysis Score value.

RingFitLatitude - Ring Analysis latitude at max score location.

RingFitLongitude - Ring Analysis longitude at max score location.

RingFitScoreValue - Ring Analysis Score value.

Returns:

Array of four double values. The values represent: latitude of final selected location, longitude of final selected location, confidence score of final selected location, and the "method" used to determine the final selected location. Possible values for the method: 1 for first guess, 2 for enhanced spiral analysis, and 5 for combo ring/spiral analysis.

FindRingScore

private static double[] FindRingScore(double FirstGuessLatitude,
 double FirstGuessLongitude,
 double[][] RingScoreAnalysisField)

Find Ring score at selected location (spiral analysis location)

Parameters:

FirstGuessLatitude - Latitude of search location.

FirstGuessLongitude - Longitude of search location.

RingScoreAnalysisField - - Array/Grid of Ring Analysis scores.

Returns:

Array of two doubles. The first value will be either -1 (if nothing was found) or 1 (if found). The second value is the value at search location in ring analysis grid (if the first value is 1).

PickFinalLocation

private static double[] PickFinalLocation(int InputPositioningID,
 double ForecastLatitude,
 double ForecastLongitude,
 double RingSpiralLatitude,
 double RingSpiralLongitude,

Determine method location scheme to use by examining various empirically-defined confidence factors. Confidence factors will be derived, with the "most confident" value used as the final automatically determined storm position.

Parameters:

ForecastLatitude - NHC/JTWC interpolated latitude position.

ForecastLongitude - NHC/JTWC interpolated longitude position.

RingSpiralLatitude - Ring/Spiral Analysis latitude position.

RingSpiralLongitude - Ring/Spiral Analysis longitude position.
