Horizontal distributions of TRMM/TMI sea surface temperatures. Horizontal distributions of TRMM/TMI sea surface temperatures (°C) on (a) 15 July 2011, (b) 31 July 2011, (c) 23 August 2012, and (d) 12 October 2012 before the passage of a typhoon and on (e) 18 July 2011, (f) 3 August 2011, (g) 26 August 2012, and (h) 17 October 2012 after the passage of the typhoons. (i to l) Differences in the TRMM/TMI sea surface temperature between before and after the passage of the typhoon (before subtracted from after). The colors within the circles indicate the central pressure of the typhoon at each position along the RSMC-Tokyo best track. The open stars, circles, and triangles show the positions of the profiling floats, as in Figure 1, except during each analysis period.
