This project will allow users to become acquainted with station models that are found on weather maps. Students will study the various atmospheric variables that are depicted on a station model and then practice on an interactive station model program.

Part 1 -

Being able to read and interpret weather maps is a very important skill in meteorology. One of the most basic skills of predicting the weather is being able to interpret a station model of a given location. A station model is a bundle of information that includes values for many different atmospheric variables that must be know in order to predict the weather. To become familiar with each specific variable represented on the station model you are to go to the following site which will provide a breakdown of these variables.

Interpreting Station Models

Once you have opened this site, you will browse through the site and answer the questions that follow based on the material presented on the website. You can answer the questions by opening a word document and answer the questions in that document and print when finished.

Questions:

1. What temperature scale is used on the station models? Why is that scale used as opposed to the Celsius scale?

2. In what location in relation to the station model is the temperature reading found?

3. There is a table that shows the various weather conditions. On the sample station model the current weather condition is represented by two parallel horizontal lines, what type of weather condition does that stand for?

4. Where is the dew point temperature found in relation to the station model?

5. How do the air temperature and dew point temperature compare if there is a high relative humidity?

6. How is cloud cover represented on the station model?

7. Decoding the surface pressure is the trickiest part of the station model. The pressure is represented as a 3 number code on the station model. How do you decode the 3 numbers to obtain the actual surface pressure value in millibars?

8. What two pieces of data does the wind barb provide?

Part 2 -

Now that you should be pretty well versed in obtaining data from a station model, it is time to actually practice. Click on the Station Model Practice link below and practice on at least 5 different station models.

Station Model Practice

****There is one variable on the station model practice that you may not yet be familiar with and that is the pressure trend, or change in pressure. Your Earth Science Reference Table provides an explanation for this variable on page 13. If you do not have your ESRT with you you can click on the link below to take a look at the station model example that is found in the reference table.***

Lastly, it is important that you are able to develop a station model if you are given the current atmospheric conditions of a location. Below is a link to the current weather conditions of Syracuse, New York. On the back of your word document with the above questions, please create a station model for those conditions. ***Use pencil you may have to make some corrections.***
