Orographic Rainfall
Orographic rainfall occurs when moist air is lifted as it flows over mountains. This phenomenon is significant in understanding local climate patterns.
- Mechanism:
- When air encounters a mountain range, it is forced to rise.
- As the air rises, it cools and condenses, leading to precipitation on the windward side of the mountain.
- Rain Shadow Effect:
- The leeward side, or rain shadow, receives significantly less rainfall, creating drier conditions.
- Significance:
- Orographic rainfall contributes to the water supply in mountainous regions and supports diverse ecosystems.
Instruments for Measuring Wind
Several instruments are utilized to measure wind speed and direction:
- Anemometer:
- Measures wind speed.
- Common types include cup and vane anemometers.
- Wind Vane:
- Indicates wind direction.
- Typically features a rotating arrow that points into the wind.
Instrument for Atmospheric Pressure
The instrument used to measure the Earth's atmospheric pressure is called a Barometer.
- Types of Barometers:
- Mercury Barometer: Uses mercury in a glass tube; the height of the mercury column indicates pressure.
- Aneroid Barometer: Uses a sealed metal chamber that expands and contracts with pressure changes.
- Importance:
- Barometers are essential in weather forecasting and understanding atmospheric conditions. They help predict storms and changes in weather patterns by monitoring pressure fluctuations.
