Part 1: Calculating Relative Humidity



Earth 111 Module 2 Formative Assessment 3: Orographic EffectPart 1: Calculating Relative HumidityInstructionsFor each problem below, calculate the correct numerical answer. In order to receive full credit, you must show all your work.QuestionsFollow the trajectory of the air mass at the following locations in the image below, and use the plot of water content to calculate the relative humidity at each:Starting point as the air mass comes onshoreHalfway up the Sierra Nevada mountainsAt the crest of the SierrasIn the low area just East of the SierrasScoring and RubricEach problem will earn a maximum of 5 points, as described in the rubric below.Work ShownPossible PointsCalculation is set up correctly2Units converted correctly1Work is legible1Correct answer1Part 2: Topography and the Orographic EffectInstructionsAnswer each question in 2-3 complete sentences. Consider each question carefully and be sure to provide a complete answer.QuestionsLook at the map of U.S. mean annual precipitation. Note two areas where it rains a lot, and explain why – are there mountains there? If so, which mountains?Do the same for two dry areas.???Are there any particular population centers that seem poorly situated based on the distribution of precipitation in the U.S.?? Explain your logic.Where is your hometown? What is the average annual precipitation in your hometown? Where do you think the water originates (i.e., from where does it evaporate to become atmospheric water vapor before it returns to the surface as precipitation)? Where do you suppose it ultimately ends up after it falls (i.e., which ocean)?Scoring and RubricEach answer will earn a maximum of 5 points, as described in the rubric below.Work ShownPossible PointsAnswer reflects careful consideration of the question2Answer is appropriate in length1Answer is legible1Answer given in complete sentences, correct spelling and grammar1Submitting your answersBring your written answers to class.
