Weather Station Lab Procedures

This video tutorial guides students through a lab on measuring relative humidity and dew point using two methods: a sling cyclometer and a metal beaker. Students will perform measurements both indoors and at a weather station. The video provides detailed instructions for each method, safety precautions, and emphasizes the importance of recording data accurately. It concludes with reminders to consult the lab manual and contact the instructor with questions.

What are the two main objectives of the lab as introduced in the video?

• Measuring wind speed and direction

• Measuring relative humidity and dew point

• Measuring temperature and pressure

• Measuring rainfall and evaporation

What is the primary tool used in the first method to measure humidity and dew point?

• Hygrometer

• Sling Psychrometer

• Anemometer

• Barometer

What should you ensure before spinning the sling psychrometer over your head?

• That there are no objects nearby

• That the floor is dry

• That the room is well-lit

• That the windows are open

What indicates the dew point temperature when using the metal beaker method?

• When the beaker feels cold to touch

• When the water starts boiling

• When the ice is fully melted

• When condensation forms on the outside of the beaker

What should you do while waiting for the ice to melt in the metal beaker?

• Heat the beaker gently

• Add more ice cubes frequently

• Continuously stir the water

• Check for condensation periodically

What additional data should be recorded at the weather station besides dew point and temperature?

• Forecast data

• Cloud cover

• Rainfall amount

• Wind speed

Why is it important to take measurements at the weather station during the first part of the lab?

• To ensure accuracy

• To compare with historical data

• To calibrate the instruments

• To avoid repeating the process

What should you do if you have questions about the lab procedures?

• Search online for answers

• Ask a classmate

• Email the instructor

• Skip the question

What is the purpose of recording forecast data weekly?

• To fulfill a course requirement

• To compare with lab results

• To predict future weather

• To ensure data consistency

What is the final step after completing the lab and recording all data?

• Ask questions if needed

• Review the data

• Clean the equipment

• Submit the lab report
