Collect hourly weather data for one dayMake weather station models of the data. Graph weather data. Write analysis and reflection of the lab.
Introduction:
The objective of this lab assignment is to determine how we can use weather data to predict the weather.
Objective
Use the National Weather Service site to choose a location for your hourly observations.
http://weather.noaa.gov/
All 24 hours are already recorded – you don’t have to do this yourself!!
Materials and Procedures
Insert Table 8 columns, 24 rows

82 1013.5 77% None NE 5 mph
74 none
Weather Data-Location: Titusville, Fl Date: September 7th and 8th
CLR = clear FEW = partly cloudy SCTD= scattered clouds BKN= very cloudy OVC= overcast NA = no information available
What does the Sky Conditions column mean?
Weather Station Models:You might not have 4 am and 4 pm exactly, use the
time closest to them Be sure to do both!!
Part III: Creating Graphs (30 Points)Time on the X axis
Temperature for the Y axis
Include units and add titles to the graphs.
Use www.chartgo.com
Copy and paste the sharedURL in the space below.
Example: http://www.chartgo.com/share.do?id=9611ba43aa
This is the part with the graphs!
Dew point is the temperature that the air is saturated with water vapor– think of humidity.
High dew point temperatures – 70 and above – tend to be more humid, and can feel uncomfortable.
If the dew point is high, there is a better chance there is fog, severe humidity, or even rain.
When the air temperature is high, you sweat to cool down – if the dew point temperature is high, your sweat doesn’t evaporate, making you feel sticky and hot!
Dew point Temperature and Air Temperature
We check air pressure in our tires – if it’s low, the tires go flat!
When you go up in an airplane or climb a very tall mountain, air pressure decreases. WHY?
Air pressure in our lives
There is less air. Zero air pressure creates a vacuum – think of outer
space No air pressure is not pretty for people! Changes in air pressure causes the wind to blow- Warm, low density air (low air pressure) rises, cool,
higher density air sinks in to replace it. Wind speed and direction is predicted using air
pressure
When you go up in an airplane or climb a very tall mountain, air pressure decreases. WHY?
1. 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.
What was the weather like that day??
Analysis and Conclusions
1. What did you learn about weather forecasting by completing the activity?
Reflection Questions:(12 points)
3. In your own words, what is the relationship between temperature, dew point, and air pressure? Think about the graphs and what we discussed!
4. Did your findings support your weather predictions? What are the possible sources of error? (I read it wrong is not always a reason!)
