Study Notes
Air Pressure and Atmospheric Dynamics
- Differences in air pressure are caused by temperature variations, humidity levels, and altitude.
- Warm air rises because it is less dense than cold air, causing it to expand and rise higher into the atmosphere.
- Atmospheric pressure is also known as barometric pressure.
- Air moves from areas of high pressure to areas of low pressure, creating wind patterns.
Characteristics of Air
- Warm air is less dense compared to cold air, which is denser and sinks closer to the Earth's surface.
- A sea breeze is created when cooler air from the ocean moves toward the land to replace rising warm air above the land during the day.
- At night, a land breeze occurs as the land cools faster than the water, causing air to move from the land to the sea.
Weather Prediction and Wind Naming
- Winds are named based on the direction they come from; for example, a south wind originates from the south.
- The persistence model for weather prediction assumes that tomorrow's weather will be similar to today's conditions.
- Meteorologists use various methods, including radar, satellite data, and computer models, to analyze current weather and forecast future conditions.
