Use the tables below for the answers. Use the data from the lab to answer questions 1 and 2
1. Look at the meteograms for 10/29/1996:
a. What is the peak gust in meters/sec for Foothills Lab? What time did it occur?
b. What is the peak gust in meters/sec for Mesa Lab? What time did it occur?
c. At the time of the peak gusts at Foothills and Mesa, what was the wind direction(s)?
d. At the time of the peak gusts at Foothills and Mesa, what was the pressure?
e. At the time of the peak gusts at Foothills and Mesa, what was the temperature, dew point, and
dew point spread (temperature minus dew point)?
