5 ESA21: Environmental Science Activities Activity Sheet The Weather Student Name: Adam Rowland Professor Name: Kara Teague Point Value: 100 points The Weather – Activity Sheet The objective of this exercise is to have you observe atmospheric conditions as well as develop your understanding of major atmospheric concepts. For this exercise, you are asked to observe and record weather conditions for four days. In addition, you are asked to answer questions about your observations, as well as respond to a series of questions on general atmospheric characteristics. In the second part of the exercise, you are asked to perform a number of calculations relating to atmospheric conditions and characteristics. Part One - Weather Observation Please read the exercise completely before you begin. Also, printing this exercise before you begin will help you in carrying out the exercise. 1. (16 points) 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.

(10 points) Describe the overall four-day temperature trend. (Remember that a trend is not an average but a qualitative statement of value over a time period (e.g., increasing, decreasing, oscillating, etc.) The trend has been rather predictable. The mornings start off cold and windy, as the day progresses it will start to warm up (usually around noon) and the clouds will dissipate, and the winds will calm down. Finally, the wind will pick back up and it will start to rain as the evening starts.
6 3. (10 points) Describe the overall four-day pressure trend. I have tried to take my pressure at the same time every day to capture the data as equally as I can. The pressure has been rising usually when I take it, but on the 24
th
it had dropped significantly due to a storm coming in. 4. (10 points) Was the wind direction consistent over the four-day period? What pattern did you observe? The wind direction was fairly consistent over the past four-day period. The pattern observed was the wind normally came out of the west and rarely changed directions. You could see this as even some of the trees had a slight tilt to them from consistent pressure on them over many years. 5. (10 points) Was the wind speed consistent over the four-day period? If not, what pattern did you observe? The wind speed was a bit inconsistent. There were certainly days where the gusts were quite high. We had several storms during the four-day timeframe so that may have altered some of the data. Had the storms not rolled in, the winds were rather consistent in the mornings and evenings. The storms came in during the afternoon and captured some very high wind gusts and weather warnings. 6. (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. The sun rose at slightly earlier times every day and set a few minutes later each day. The days are certainly getting longer as we approach the spring season here. This would make sense as Germany is in the Northern and Eastern hemisphere and would be entering a longer time in the sun. 7. (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? In order to understand the environment you have to understand how weather plays a part in it. The field of science strives to predict short-term weather patterns as well as long-term climate changes. If you can understand the impact weather plays on the environment you have a better chance of predicting things such as earthquakes and storms. You can use weather data in storm tracking. Understanding how different pressure systems interact can help you predict storm cloud formations or even tornadoes in certain areas. 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 100°C and freezes at 0°C. 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) 8. (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 -9.4 degrees Celsius 75 degrees Fahrenheit 23.8 degrees Celsius 32 degrees Fahrenheit 0 degrees Celsius 31 degrees Celsius 87.8 degrees Fahrenheit 13 degrees Celsius 55.4 degrees Fahrenheit 0 degrees Celsius 32 degrees Fahrenheit
