ESSC 101 Lab 8: Skew-T Diagrams and Atmospheric stability Report 1. After reading the Lab procedures, formulate a question that will be answered after completing your lab. 2. Describe the methodology you will use to complete your laboratory exercise. (Remember that would include, an explanation of how you obtained the data, and how the materials will be used to complete your lab.) 3. Record Data: Part 1 Reading a Skew-T diagram Questions Examine the Skew-T diagram (Figure 1 ) in the procedures and answer the following questions. 1. What is the data that is plotted on a Skew-T diagram? 2. What is the surface temperature for FFC on 3/11/22 00Z? (Hint: It is printed at the surface pressure isobar) The surface temperature is 63 F (about 17 C). 3. What is the surface dewpoint temperature for FFC on 3/11/22 00Z? The surface dewpoint temperature is 52 F (about 11 C). 4. Examine the Skew-T diagram. Find the temperature lines (for 0 and -20 C, marked in blue) in the Skew -T diagram in Figure 1. At what pressure in the atmosphere does the temperature go below freezing (0C)? The pressure at which the temperature goes below freezing is about at 675mb. 5. Examine the relationship of the temperature and dew point temperature on the the Skew- T diagram between what heights (pressure) would you most likely expect to see clouds develop? (Remember that Clouds need saturated conditions, requiring similar
temperature and dewpoints) We will most likely see clouds between about 820mb and about 990mb. 6. Find the wind data on the right hand side of the diagram. Do the wind directions vary with decreasing pressure (higher altitudes)? The wind direction mostly stays the same from 100mb to 850mb (west winds). After 850mb, the wind direction changes southwest. 7. At what pressure, do you find the highest wind speeds? The highest wind speeds can be found between 100mb to 200mb. 8. Find the dashed line representing the calculated adiabatic temperature. What is the color of this line? And is it to the left or right of the environmental temperature? The color of the line representing the calculated (theoretical) adiabatic temperature is dark red / maroon. This line is mostly printed to the left of the environmental temperature.
