Forecasters can also use this type of format to analyze fronts, the amount of stability in the atmosphere, and temperature advection solely based on the slopes and vertical spacing of isentropic surfaces along the cross section. You can also see a more uniform moisture distribution through the atmosphere along an isentropic cross section as opposed to an atmospheric sounding. Meteorologists taking upper air observations are as basic to diagnosing the atmosphere as a doctor taking your blood pressure to diagnose the condition of your heart. With these simple measurements we can analyze many structures in the upper atmosphere and understand the dynamics of weather systems aloft. Without these observations we would be as blind to the structure of disturbances aloft as not having satellite pictures.
