[1] In the paper “Genesis of twin tropical cyclones as revealed by a global mesoscale model: The role of mixed Rossby gravity waves” by Bo-Wen Shen et al. (Journal of Geophysical Research, 117, D13114, doi:10.1029/2011JD017450, 2012), errors were introduced to Figures 4, 6, 10, and 21 during production. The correct figures and captions are given below.

Figure 4.

Initial conditions in terms of wind vectors and geopotential heights at (a) 850-hpa and (b) 500-hpa from the NCEP T254 analyses. (c) The same as Figure 4a except for the NCEP 2.5° reanalysis. (d) The difference in 850-hpa winds (vectors) and geopotential heights (with contour lines of 6 and 8) between the NCEP T254 analyses and 2.5° reanalysis. This shows the dependence of the resolved MRG wave.

Figure 6.

The 850-hPa winds (vectors) and geo-potential heights (shaded) at 0000 UTC 3–5 May 2002 from (a, c, and e) NCEP T254 analyses and (b, d, and f) the control run. There were three gyres with cyclonic circulation centers, S1 N1 and S2. A reduction in the MRG wavelength can be seen by the reduced distance between gyres S1 and S2. During the period of MRG wave intensification, the northern vortex moved poleward in association with a northward extension of the MRG wave and later developed into TC 01A. The gray oval in Figure 6c indicates the circulation of gyre S2 which is similar to that of a MRG wave in Figure 3c.

Figure 10.

Longitude-height cross sections of meridional winds at 0000 UTC 4 May 2002 averaged over latitudes (a and c) 5°S to the equator and (b and d) from the equator to 5°N. Figures 10a and 10b show the NCEP T254 analyses while Figures 10c and 10d show the control run. S2 and N1 roughly indicated the location of the gyres.

Figure 21.

Hovmoller diagram of the vorticity (10−5 s−1). Shaded areas show vorticities averaged over latitudes 10°S and 0°, while contour lines (with selected values of 1, 2, 4, and 6 × 10−5 s−1) show vorticities averaged over latitudes 0° and 10°N. (a) The CNTL run, (b) the EXP-A run, (c) the EXP-B run, and (d) the EXP-C run. Local minima (blue) indicate the locations of gyre S1 and gyre S2. Dense contour lines between gyres S1 and S2 indicate the location of gyre N1.
