Keep a log of atmospheric conditions for 4 days and record the following information. Find out information from any one of the following sources such as local newspapers, television news, the Weather Channel, or Weather Underground.



  Day One Day Two Day Three Day Four
High Temperature (F)        
Low Temperature (F)        
High/Low Difference        
Air Pressure (AP)        
AP Rising or Falling?        
Wind Direction        
Wind Speed (mph)        
Time of Sunrise        
Time of Sunset        
Length of Daylight        




Answer the following questions with regards to the atmospheric observations you made and then complete the temperature conversions below.


  1. (10 points)
  2. Describe the overall four-day temperature trend.
  3. (Remember that a trend is not an average but a qualitative statement of value over a time period (e.g., increasing, decreasing, oscillating, etc.)






  1. (10 points) Describe the overall four-day pressure trend.


  1. (10 points) Was the wind direction consistent over the four-day period? What pattern did you observe?







  1. (10 points) Was the wind speed consistent over the four-day period? If not, what pattern did you observe?









  1. (10 points) What pattern did you observe with regards to the amount of daylight over the four-day period? Are the days getting shorter or longer? Relate your answer to the hemisphere and season you are currently in.








  1. (10 points) What does the study of weather have to do with environmental science? What ways can you think of weather data being used in an environmental study?




Part Two – Temperature Conversion


Temperature can be measured in different scales. In the U.S. we use the measure temperature in degrees Fahrenheit (F). Most other countries and many scientists use the Celsius (C) scale. In the Celsius scale, water boils at 100C and freezes at 0C. The formulas for converting from one temperature scale to the other are as follows:


F = (9/5 x C) + 32 and C = (5/9) x (F 32)


  1. (24 points) Complete the following calculations and place your answer in the center column below. Keep track of positive and negative values:



15 degrees Fahrenheit   degrees Celsius
75 degrees Fahrenheit   degrees Celsius
32 degrees Fahrenheit   degrees Celsius
31 degrees Celsius   degrees Fahrenheit
13 degrees Celsius   degrees Fahrenheit
0 degrees Celsius   degrees Fahrenheit
