What Can You Learn from a Thermometer on a Rising Balloon?
ES1702  Soundings at Different Latitudes
Data from National Weather Service

By comparing the height of the tropopause at different latitudes, you can visualize the global shape of the troposphere. These graphs show sounding data from a high latitude location (Barrow), a middle latitude location (Riverton), and near the equator (Rochembeau). All three soundings were taken at 12Z, August 20, 2001.

Recall that the altitude at which the temperature stops decreasing the tropopause.

6. How does the height of the tropopause change from the polar region to the equator?

7. How does the minimum temperature of the tropopause change from the equator to the polar region?
