(continued) The NASA DC-8 left Yokota Air Base, Tokyo, at section of Plate 2. The DC-8 entered the eye at about 0105 UT on September 27, 1991, as Mireille approached 0457 UT through a gap in the highest clouds and remained Kyushu from the southwest with a central pressure of 935 in the eye, which by then was beginning to fill in with hPa. A boundary layer mn at 300 rn was made at about clouds, until about 0535 UT, then exited to the northeast. 28øN, 136øE, and the aircraft then climbed to 11.3 km and At 0550 UT the aircraft headed toward the southeast at 12 penetrated the cloud region surrounding the eye (see Plate km and returned along the same path, heading northwest, 1 satellite image) which, according to cloud top at 11 km. The purpose was to sample the atmosphere more temperatures and vertical temperature profiles, exceeded or less perpendicular to the outflow from Mireille. At 15.5 km in height. The overall aircraft track is summarized 0638 UT, the end of this maneuver, the DC-8 turned in the horizontal projection of Figure 2, which includes the toward the east-northeast and returned toward Tokyo, aircraft-measured wind velocities, and in the vertical cross where it landed at 0739 UT. .:57 129.70E 138.00E
