# Min-Max temperatures

Here is a lesson dealing with minimum and maximum temperatures at certain cities in the U.S. I found this data after browsing through the National Center for Atmospheric Research (NCAR)

In this lesson, we will be looking at the week long predicted and normal minimum and maximum temperatures for various cities throughout the U.S.

Let's take a look at some predicted and normal temperatures.
Choose a section of the U.S.

To access the data sets, there are two ways. One way is to use the software NCSA Mosaic at the Universal Resource Locator (URL).

The address is- gopher://wx.atmos.uiuc.edu/11/Regional

Choose one of the following files:

Seven Day Min-Max Temp Fcst (Eastern)

Seven Day Min-Max Temp Fcst (Midwest)

Seven Day Min-Max Temp Fcst (Northwest)

Seven Day Min-Max Temp Fcst (Southwest)

The other way is to use the TurboGopher software.

Choose a city. Look at the minimum predicted temperature and the normal minimum temperature throughout the week.

1. What is the average predicted temperature for the week?

2. What is the average normal temperature for the week?

3. What is the difference of these averages?

4. Is the predicted average close to the normal average (under 5 degrees)?

Look at the predicted temperature for the week.

5. Are there any two temperatures that have a difference of 5 degrees or greater? (for example: are there 2 days of temperatures 71 degrees and 76 degrees?) If so, on which days? (put these days in pairs)

Look at the normal temperatures for the week.

6. Are there any two temperatures that have a difference of 5 degrees or greater? If so, on which days?

7. If you have two days where the difference of the predicted temperatures is 5 degrees or greater and two day where the difference of the normal temperatures is 5 degrees or greater, are these pairs the same days?
