The Impact of Assimilating Atmospheric Infrared Sounder Observation on the Forecast of Typhoon Tracks
Figure 4
The contour plots for the “forecast error of the control run” minus “forecast error of an individual forecast with AIRS data” under a given pair of values of LEN_SCALING (abscissa) and VAR_SCALING (ordinate). The forecast error is for the typhoon track measured by the distance between the predicted and observed (best track) locations of the center of the typhoon. A positive value in the plot indicates that the forecast with AIRS data produces a smaller error compared to the control run (that does not incorporate AIRS data). Contour interval is 25 km. Positive values are shaded in gray.
