Study Notes
The Science of Wind and Global Wind Patterns
- Wind patterns are linked to global air temperature patterns, influenced by insolation from the Sun and key factors like latitude, elevation, proximity to the ocean, and surface type.
- Warm air rises while cool air sinks due to differences in density, and air molecules have weight, leading to atmospheric pressure.
- Atmospheric pressure varies with location, season, and time of day, with wind smoothing out pressure differences created by air temperature patterns.
- Meteorologists use air pressure measurements to forecast weather, with low pressure areas (lows) having less pressure than standard sea level pressure.
- Lows can be known as depressions or cyclones, and are associated with cloudy and rainy weather due to rising air drawing winds towards the center.
- High pressure areas (highs) result from cooling and denser air sinking, causing clear and sunny weather.
- Air moves between high and low pressure areas to balance energy, creating winds, with the difference in pressure called a pressure gradient.
- Local wind phenomena, like sea breezes, result from temperature differences between land and sea.
- The equator experiences a belt of low pressure known as the equatorial trough, while the poles have high pressure due to cold, sinking air.
- The Coriolis effect, caused by the Earth's rotation, makes winds appear to curve as they travel, affecting wind directions.
- The Coriolis effect causes winds to curve as they travel over the rotating Earth, influencing wind patterns and directions.
- Wind patterns are influenced by a combination of factors including air temperature, atmospheric pressure, and the Coriolis effect due to the Earth's rotation.
