Cevap

Wet-and-dry bulb psychrometer
The wet-and-dry bulb psychrometer (hygrometer) measures atmospheric relative humidity by evaluating the difference between dry-bulb air temperature and wet-bulb temperature caused by evaporative cooling.

Adım Adım Çözüm

1
Identify the weather parameter being measured in the question stem
The target weather parameter is relative humidity (atmospheric moisture).
The stem describes calculating atmospheric moisture levels using dry and wet bulb temperature readings.
2
Match the specified weather parameter and construction mechanism to the standard meteorological instrument
The wet-and-dry bulb psychrometer (a type of hygrometer) is the instrument designed with two thermometers to measure relative humidity.
Water evaporating from the wet muslin sleeve cools the wet-bulb thermometer, creating a depression that correlates directly with relative humidity.
