Meteorologists draw conclusions based on all known weather data. They continually update their forecasts based on new data. This is one reason that the forecast can change from day to day and from hour to hour. Now, it is your turn to predict the weather.

Your assignment for this lesson will include activities designed to determine your ability to analyze weather maps. Using the information you have learned in the lesson, you will practice your weather-forecasting abilities.

Use this Laboratory Report Format for submitting your work for this lab.

Here is the worksheet you do. Fill it out.

Lab Report Format for Meteorology Lab

Title: Meteorology Lab

Introduction:You will be required to collect hourly weather data for one day. Once you have collected 24 hours’ worth of weather data, you will create surface weather station models of the data. Then, you will graph some of the weather data to draw conclusions about the relationships between the data. Finally, you will write a laboratory report of your results.

Objective: The objective of this lab assignment is to determine how we can use weather data to predict the weather.

Problem:  How can we use the relationships among weather data to produce a forecast?

Hypothesis: Using the relationships from weather data write a hypothesis about how weather may be forecasted. Remember this is your hypothesis. Make sure it is reasonable and done before you plot the weather station models and create your graphs.

Materials and Procedures: Use the National Weather Service site to choose a location for your hourly observations.

All 24 hours are already recorded and data can be transferred into chart.

Data and Observations:

Part I: Record all 24 hour weather data for your location. Please fill in all data below using the data from the National Weather Service site. Be sure to include the date and location for your data.(26 points) Weather Data – Location:              Date:

Time of Day	Temperature (F°)	Air Pressure	Humidity	Cloud Cover	Wind Speed and Direction	Dew Point (F°)	(Additional Weather Data)

Part II: Use the diagram below to record your surface weather data collected for 4 AM and 4 PM. (24 points) DAY: 4 AM

1. Temperature:_______

2. Dew Point:______

3. Barometric Pressure:_____

4. Wind Direction – Choose One: N, NE, E, SE, S, SW, NW W

5. Wind Speed: _______

6. Cloud Cover – Choose One: 0%, 25%, 50%, 75%, 100%

NIGHT: 4 PM

1. Temperature:_______

2. Dew Point:______

3. Barometric Pressure:_____

4. Wind Direction – Choose One: N, NE, E, SE, S, SW, NW W

5. Wind Speed: _______

6. Cloud Cover – Choose One: 0%, 25%, 50%, 75%, 100% Part III: Creating Graphs (30 Points)

1. Using the Weather Data from the chart construct a line graph using Time on the X axis and Temperature for the Y axis. Make sure to plot both the temperature and dew point on your graph. Be sure to include units and add titels to the graphs. Use the following website to make an easy line graph: ChartGo. Once your graph is created please copy and pase the sharedURL in the space below. Example: http://www.chartgo.com/share.do?id=9611ba43aa

• Using the Weather Data from the chart construct a second line graph using Timeon the X axis and Air Pressure for the Y axis. Be sure to include units and add titles to the graphs. Use the following website to make an easy line graph: ChartGo. Once your graph is created please copy and pase the sharedURL in the space below. Example: http://www.chartgo.com/share.do?id=9611ba43aa

Analysis and Conclusions: (8 points)

In your own words, write an analysis of the weather that occurred on the day you selected, based on the surface weather station models you created.

Reflection Questions:(12 points)

1. What did you learn about weather forecasting by completing the activity?
2. In your own words, how are weather data used to make forecasts?
3. In your own words, what is the relationship between temperature, dew point temperature, and air pressure?
4. Did your findings support your weather predictions? What are the possible sources of error?
