Method Detail

CalculateIntensity

public static void CalculateIntensity(int RedoIntensityFlagValue,
                                      boolean RunFullAnalysis,
                                      java.lang.String HistoryFileName)

Compute intensity values CI, Final T#, and Raw T#.

Parameters:

RedoIntensityFlagValue - Recalculate Intensity flag value.

RunFullAnalysis - Whether or not a full analysis should be performed.

HistoryFileName - Path to history file.

adt_TnoRaw

public static double[] adt_TnoRaw(int RedoIntensityFlag,
                                  java.lang.String HistoryFileName)

Compute initial Raw T-Number value using original Dvorak rules

Parameters:

RedoIntensityFlag - Recalculate Intensity flag value.

HistoryFileName - Path to history file.

Returns:

Array of two doubles. First value represents intensity estimate, and the second is the analysis flag.

adt_TnoFinal

public static double adt_TnoFinal(int TimeAvgDurationID)

Compute time averaged T-Number value using previous and current intensity estimates.

Average using a time-weighted averaging scheme.

Parameters:

TimeAvgDurationID - Time average duration flag. Use 0 for 6 hour and 1 for 3 hour.

Returns:

Final T# value.

adt_CIno

public static double[] adt_CIno(java.lang.String HistoryFileName)

Compute final CI-Number applying various Dvorak Rules, such as the now famous Rule 9.

Parameters:

HistoryFileName - Path to history file.

Returns:

Array of two doubles. First value represents current intensity, and the second represents the current strengthening/weakening flag.

adt_latbias

public static double adt_latbias(boolean InitStrengthTF,
                                 boolean LandFlagTF,
                                 java.lang.String HistoryFileName,
                                 double InputLatitude,
                                 double InputLongitude)

Apply Latitude Bias Adjustment to CI value.

Parameters:

InitStrengthTF -

LandFlagTF - Flag that represents land status.

HistoryFileName - Path to history file.

InputLatitude - Current latitude of storm.

InputLongitude - Current longitude of storm.

Returns:

Adjusted MSLP value.

adt_scenesearch

public static double[] adt_scenesearch(java.lang.String HistoryFileName,
                                       boolean InitStrengthTF,
                                       boolean LandFlagTF)

Search for valid scene range for Latitude Bias Adjustment application. Inputs : None Outputs : AdjustmentMultFactor_Return - multiplicative value for merging Return : 0 - first record in new history file 1 - non Enhanced Infrared scene or intermediate/merging application 2 - entering/leaving valid adjustment time period. Also used for non-history file intensity analysis (full adjustment)

Parameters:

HistoryFileName - Path to history file.

InitStrengthTF -

LandFlagTF - Over land?

Returns:

Array of two doubles. The first value represents latitude bias adjustment, while the second value represents the adjustment's multiplicative factor.
