An Analysis of Tropical Cold-Point Tropopause Warming in 1999

Figure 10

Time-pressure cross sections of temperature (colors) and zonal wind (contour levels) anomalies from 1994 to 2005. The contour interval of zonal wind is 10 m/s, and the value range is from −40 m/s to 40 m/s. The temperature anomalies are calculated here by removing the seasonal cycle. The zonal anomalies are calculated here by removing the time averaged zonal wind from 1994 to 2005.
