Meteorology 3410: Assignment 5
Due October 5
Purpose:
Programming and statistical applications to weather variations. Variations in air and lake temperature over the Great Salt Lake will be analyzed.
Assigment
copy the 2 data files /home/meteor/x/class/jhorel/3410/hat* to a subdirectory in your directory. These contain air and lake temperature on two different days.
become familiar with the format of the data and write a perl, c, or fortran program to read the data. (Hint: modify one of the existing programs in the language of your choice.)
Plot time series of air ahd lake temperature on the same figure. Do a separate figure for each day.
Compute the mean air and lake temperatures, the standard deviation of the air and lake temperatures, and the linear correlation between air and lake temperature on both days.
- What is the variability in air temperature relative to that of lake temperature?
- The linear correlation between lake and air temperature indicates that the two variables are weakly or strongly correlated?
- How does the variability and linear relationship vary between the two days?
Compute the slope of the line of best fit and the intercept on both days.
Use xmgr as described in class to plot the output as scatter diagrams. Overlay the line of best fit. (Hint: use the slope and intercept to define a couple of points). How well does the linear relation between air temperature and lake temperature describe the variability of the two fields?
Hand in the program, text and graphical output files, and answers to the above questions.
