The latter case is the only reversed (positive) lapse rate value in the whole of Table 3, where the normal lapse rate profile (temperature decrease with height) temporarily changes sign at 18:00 on average over the six days (there is another, already mentioned near-neutral lapse rate of-0.3[degrees]C [km.sup.-1] for S3-S2 at the same time).
