# WEAX 201 ERAU Meteorology Density Altitude Training Activity Hypothesis & Conclusions

hypothesis and conclusions

I have attached the worksheet with my answers.

In the Data section of the Density Altitude Experiment Worksheet are three tables. Each table provides five different scenarios of sea level pressure, station pressure*, temperature, and dew point temperature for the given airport. Recall that the dew point temperature is a measure of the air’s water vapor content.

After analyzing the differences in the airports and the scenarios, develop a hypothesis (i.e., make a prediction) for how the differences in airport elevation and the different scenarios of pressure, temperature, and dew point temperature will impact the air density and the density altitude. First, think about the effect of the airport elevation alone on air pressure and density, and the density altitude. Then, for each scenario in a given table, consider how the calculated value of density altitude should compare to the airport’s elevation. Type your hypothesis in the Hypothesis section of the experiment worksheet.

After completing the tables, analyze your results, then draw some conclusions by formulating a short discussion for each of the prompts 1-5 below. Type your discussions for each of the prompts in the Conclusions section of the experiment worksheet.

Evaluate the correctness of your hypothesis based on the experiment results.

After making a rough comparison of the “average” (ball-park) density altitude value for each airport, explain why station elevation has the greatest impact on the value of the density altitude.

Analyze the data for each airport/station elevation separately to determine which factor – station pressure, temperature, or dew point temperature – has the MOST affect on density altitude. Provide some justification for your answer.

Analyze the data for each airport/station elevation separately to determine which factor – station pressure, temperature, or dew point temperature – has the LEAST effect on density altitude. Provide some justification for your answer.

Make the appropriate choices below (High OR Low) to create the combination of factors that creates the highest value of density altitude:

High/Low station elevation

High/Low temperature

High/Low dew point temperature

Then, develop a sentence that summarizes the conditions that create a high density altitude situation.
