Overview of common weather instruments used to measure atmospheric conditions.

It looks like you've uploaded an image of a chart titled "Weather Instruments", which lists various instruments used to measure different weather conditions. Each instrument is described with its function and includes a picture.

Here's the breakdown of each instrument from the chart:

---

1. Thermometer

- Function: Measures air temperature.
- Details: Contains liquid (usually mercury or alcohol) that expands and contracts with temperature changes. As temperature increases, the liquid expands and rises in the tube.

---

2. Wind Vane

- Function: Measures wind direction.
- Details: Shows which direction the wind is blowing from. The arrow points into the wind, so if it's pointing north, the wind is coming from the north.

---

3. Rain/Snow Gauge

- Function: Measures the amount of rain/snow that has fallen.
- Details: A cylindrical container that collects precipitation. The depth of water or melted snow is measured to determine how much precipitation occurred.

---

4. Barometer

- Function: Measures air pressure.
- Details: Tells whether air pressure is rising or falling. Changes in air pressure can indicate approaching weather systems (e.g., storms or clear skies).

---

5. Hygrometer

- Function: Measures humidity.
- Details: Measures the amount of moisture (water vapor) in the air. High humidity means more moisture in the air; low humidity means drier air.

---

6. Anemometer

- Function: Measures wind speed.
- Details: Made of small cups and a vertical shaft. The cups catch the wind and spin around. The faster they spin, the higher the wind speed.

Summary:

Each instrument plays a crucial role in collecting data for weather forecasting:
- Temperature → Thermometer
- Wind Direction → Wind Vane
- Precipitation → Rain/Snow Gauge
- Air Pressure → Barometer
- Humidity → Hygrometer
- Wind Speed → Anemometer

These tools are often used together in weather stations to provide a complete picture of current weather conditions.
