Weather Analysis

Select ONE station in the United States you want to record the daily data from the Mesowest site. Example: the city where you were born; your favorite city to visit; or major cities in Arizona (Tucson, Phoenix, Flagstaff).
 

Step 1: Create a user account on Mesowest

 

 

 

Step 2: Click on ‘Surface Weather Maps’

 

 

Step 3: Find the station you selected by selecting the desired state and city

 

 

Step 4: Refresh Map

 

 

Step 5: Find the station you want to download data. Finding the station by moving your mouse cursor and click on the ‘black dot’. This is what you will see: weather time series for the last 24 hours. Then go to ‘Download data’

Step 6:

 

 

Step 7: You will received a excel format file containing all the data you selected in previous step. Make sure you save the file to your computer before existing.

What data to plot?

Record the temperature (T), dew point (TD), and relative humidity (RH) for the time and date. Repeat for each date. See data sample (below and D2L) and plotting sample using Microsoft excel on D2L. Don’t know how to use excel? You can use any software you wish. You can also plot the graph by hand using old school graph paper. You can put them all on the same plot if you’d like, but use a different vertical axis scale for the relative humidity and try to arrange the two axis. Make sure to use different colors for each time series for better viewing.

What happens after I finish plotting the temperature, dew point temperature and relative humidity?

You should determine if there is a general upward or downward trend to temperature and relative humidity through the period. Write a brief (≤ 3 pages double spaced) summary of the trends in the data—whether the temperature goes down as we might expect during this season, whether there is an apparent trend in relative humidity versus time, and whether (and how) the variables seem to correlate with each other. Also discuss any interesting maxima and minima in the time series. Where there any extreme weather events?

 

How to submit Homework #1 Part I?

On February 21, you must exchange your completed lab assignment with a peer

(classmate) in this class. Your peer will read through your lab report and make corrections to spelling and grammar, and make comments and suggestions about how to improve your report.  This process is known as “peer review”.

 

Homework #1 Part II (Due Mar 07)

On March 07, you will submit TWO reports: your ORIGINAL report (the version you have on February 21) and EDITED report (changes based on your classmate’s comments). Make sure you also include WHO edited your report.
