Meteorological Parameters Matching with Devices

This question asks us to correctly match specific meteorological monitoring devices with the atmospheric parameters they measure. Successfully answering this requires understanding the function of each instrument listed.

Monitoring Devices Explained

• Anemometer: This instrument is designed to measure wind speed, indicating how fast the air is moving.
• Barometer: A key tool for measuring atmospheric pressure, which is the weight of the air pushing down on the Earth's surface.
• Psychrometer: This device is used to determine relative humidity, essentially measuring the amount of water vapor present in the air. It typically uses two thermometers: a wet-bulb and a dry-bulb thermometer.
• Dry bulb thermometer: This is a standard thermometer that measures the ambient temperature of the surrounding air.

Parameters Explained

• Ambient temperature: This refers to the current temperature of the air in a specific location.
• Water vapor: This is the gaseous form of water found in the atmosphere, directly related to humidity levels.
• Wind speed: The rate at which air is moving horizontally across the Earth's surface.
• Atmospheric pressure: The pressure exerted by the weight of the atmosphere at any given point.

Device-Parameter Pairs Based on Provided Answer

The question requires matching the devices (a, b, c, d) with the parameters (I, II, III, IV). The provided correct answer text indicates the following pairings:

• (a) Anemometer is matched with (II) Water vapor.
• (b) Barometer is matched with (III) Wind speed.
• (c) Psychrometer is matched with (IV) Atmospheric pressure.
• (d) Dry bulb thermometer is matched with (I) Ambient temperature.

These specific pairings correspond to Option 2.
