Basic weather instruments are tools used to measure and observe atmospheric conditions. Common examples include thermometers for temperature, barometers for air pressure, hygrometers for humidity, anemometers for wind speed, and rain gauges for precipitation. These instruments provide essential data for weather forecasting and climate studies. By collecting and analyzing information from these devices, meteorologists can better understand weather patterns and predict changes in the environment.

What is a thermometer used for?
To measure temperature, indicating how hot or cold the air or a surface is (in °C or °F).
What does a barometer measure and why is it useful?
Air pressure. Tracking changes helps forecast weather; rising pressure often means calmer weather, while falling pressure can indicate storms.
What is a hygrometer used for?
Measuring humidity in the air, typically reported as relative humidity (%).
What does an anemometer measure?
Wind speed (and, in some models, wind direction) to describe how fast the air is moving.
What is a rain gauge used for?
Measuring the amount of precipitation, usually rainfall, over a specified period (in mm or inches).
