How is weather predicted or forecasted

 *Weather prediction*, also called *weather forecasting*, is the process of using *scientific tools and data* to predict what the weather will be like in the *future*—for example, whether it will *rain, be sunny, windy, or cold*.

*How Weather Is Predicted:*

*1. Observation and Data Collection*

- Weather stations, satellites, and radars collect data about:

  - Temperature  

  - Humidity  

  - Wind speed and direction  

  - Air pressure  

  - Cloud movement

*2. Use of Weather Instruments*

- *Thermometers* measure temperature.  

- *Barometers* measure air pressure.  

- *Anemometers* measure wind speed.  

- *Rain gauges* measure rainfall.  

- *Satellites and radar* help monitor clouds and storms from space.

*3. Weather Models and Computers*

- Scientists use powerful computers and mathematical models to analyze the data.  

- These models simulate the atmosphere and show how weather might change in the coming hours or days.

*4. Interpretation by Meteorologists*

- Trained experts (called *meteorologists*) study the data and computer models to make forecasts.  

- They decide the *likelihood* of rain, sunshine, storms, etc.

*5. Public Weather Reports*

- Forecasts are shared through *radio, TV, websites, apps, and newspapers*, helping people plan ahead.

*Conclusion*

Weather forecasting uses scientific tools, observations, and computer models to predict future weather. It helps people *prepare for rain, sunshine, storms, or extreme weather*, making it important for farming, travel, and safety.
