An Analysis of Tropical Cold-Point Tropopause Warming in 1999

Figure 4

Longitude-pressure cross sections of tropical mean (20°N–20°S) vertical velocity anomalies (a and c) and meridional distributions of tropical mean OLR anomalies (b and d) during the “prewarming” (a and b) and “postwarming” (c and d) periods in 1999. (e and f) Same as Figure 2(c) but for vertical velocity anomalies (e) and OLR anomalies (f), respectively.
