How Weather Forecasts Work
Weather forecasts are created using complex computer models that analyze current atmospheric conditions and predict future weather patterns. Meteorologists use data from weather stations, satellites, and radar systems worldwide.
Common Weather Terms
- Temperature: Measured in Celsius or Fahrenheit, indicates how hot or cold it is.
- Humidity: The amount of moisture in the air, expressed as a percentage.
- Wind Speed: How fast air is moving, usually measured in km/h or mph.
- Pressure: Atmospheric pressure, measured in millibars or inches of mercury.
- UV Index: Measures the strength of ultraviolet radiation from the sun.
- Visibility: How far you can see clearly, affected by fog, rain, or pollution.
