Question

Name Name: Section Day Time: Laboratory 2: Vertical Profiles of the Atmosphere (70 pt) Upon completion of this lab, students will be able to: . Describe how vertical profiles of the atmosphere are determined. e Explain the changes in metcorological variables with altitude. Pre-Laboratory the at ios you have had experiences detecting near-surface local and horizontal profiles of Th us far, you have had experiences detecting near-surface local and horizontal profiles of the atmosphere. In this experiment, you will investigate atmospheric changes in the vertical direction. Air temperature, humidity, wind speed, and wind direction change as you move away from Earth's surface depending on factors at the surface. Here are some questions to think abou before beginning the laboratory. 1. What temperature trend do you expect to see with increasing altitude? (2 pt) 2. What factors affect vertical changes in humidity? (2 pt) . Why does wind speed change with increasing altitude? (2 pt) Laboratory up: 4-5 students up Members

Explanation / Answer

1) Temperature decreases with the altitude.

This is called lapse rate.

Generally temperature decreases about 6.5° C for every 1000 meters .

2) Factors affecting vertical change in humidity are
