🔍 Key Concepts

• Psychrometer function (dry bulb vs. wet bulb readings) • How evaporation from the wet bulb affects temperature • What weather elements are found in psychrometric tables

💭 Think About

• What does it mean if the wet bulb temperature is much lower than the dry bulb temperature? What does that say about moisture in the air? • When mariners look up values in psychrometric tables, which air properties related to moisture content are they usually interested in? • Which of the answer choices are directly related to how much water vapor is in the air, rather than wind or pressure?

✅ Before You Answer

• Identify which choices deal with moisture in the air rather than motion of air or pressure. • Recall that a psychrometer does NOT have any device for measuring wind speed or pressure directly. • Think about which weather elements are typically expressed as a percentage or as a temperature at which condensation occurs.
