An Analysis of Tropical Cold-Point Tropopause Warming in 1999

Figure 2

The spatial distributions of CPTT anomalies during the (a) “prewarming” and (b) “postwarming” periods in 1999. CPTT anomalies are calculated by subtracting the CPTT daily climatology based on the period from 1994 to 2005 from the daily CPTT values in 1999. (c) CPTT differences between the “postwarming” and “prewarming” periods.
