Exercise 1

This exercise will demonstrate how weather, ie temperature, precipitation and pressure, changes as a cold front passes through the Eastern United States. 

What is a cold front?

A cold front marks the transition zone between a large blob of cold air and a large blob of warm air.  The cold front marks the leading edge of the denser air pushing forward which lifts up the less dense warm air.  As this warm air is lifted upward, it cools and becomes saturated.  This saturated rising air condenses forming clouds and eventually, precipitation.  The faster the cold front advances, the more intense the precipitation.

What does a frontal passage look like?

The following variables can be monitored to identify when a cold front passes through a given location:

  1. pressure
  2. temperature
  3. rainfall

Using this information about pressure, temperature and rainfall, save this Word document and answer the questions.

 

Exercise 2

The following exercise will allow you to challenge your understanding about weather changes along a cold front. 

Have you played the game “Where’s Waldo”?  You and your classmates are challenged to identify the location of your station with just the time series of weather information.  To narrow your choice, the possible choices for your locations are be the following:

 

-         New Martinsville, WV

-         Panama City, FL

-         Louisville, KY

-         Brownsville, TX

-         Moorehead City, NC

-         Fargo, ND

The goal of this activity will be two fold:

1)  Identify the correct location of your city

2)  Predict the time series of your data for the next 36 hours

You and your group have been assigned one station to identify.  Click on respective link on the left menu.  You may work together in your team as well as collaborate among teams to make your identification.

Good luck!
