Study Notes
Understanding Global Wind Patterns
- Global wind patterns are linked to global air temperature patterns, which are influenced by factors like latitude, elevation, proximity to the ocean, and surface type.
- Warm air is lighter and tends to rise, while cool air is heavier and tends to sink due to differences in air density.
- Atmospheric pressure, caused by the weight of air, varies with location, season, and time of day.
- Wind is the atmosphere's way of equalizing pressure differences created by daily and seasonal air temperature patterns.
- Meteorologists use air pressure measurements to forecast weather, with low pressure areas indicating less air pressing down on the Earth's surface.
- Lows, also known as depressions or cyclones, result from air heating and expanding, drawing winds towards the center and causing cloudy and rainy weather.
- High pressure areas, known as highs or anticyclones, result from cooling and densifying air, bringing clear and sunny weather.
- Air moves between high and low pressure areas to balance energy, creating winds due to pressure gradient, the difference in pressure between highs and lows.
- Local wind patterns, like sea breezes, are caused by temperature differences between land and sea, resulting in air rushing from the sea onto the land.
- The equator experiences low pressure due to consistently warm air, while the poles experience high pressure due to cold, sinking air.
- Winds do not just blow north and south due to the Coriolis effect, which causes moving objects to appear to curve as they travel over the rotating Earth.
- The Coriolis effect influences wind direction, causing a deflection to the right in the northern hemisphere and to the left in the southern hemisphere.
