Study Notes
Weather and Climate Definitions
- Weather refers to short-term atmospheric conditions including temperature, precipitation, air pressure, wind, and clouds.
- Climate is the long-term average of weather patterns in a specific area, assessing conditions month by month over the years.
Weather Components
- Temperature indicates how hot or cold the air is.
- Precipitation encompasses all forms of water falling from the atmosphere, such as rain, hail, snow, fog, and dew.
- Air Pressure measures the weight of the atmosphere; warm air creates low pressure and cool air creates high pressure.
- Wind is the result of air movement from high-pressure areas to low-pressure areas, affected by pressure differences; stronger differences result in faster winds.
- Clouds consist of tiny water droplets or ice crystals suspended in the atmosphere.
Climate Influencing Factors
- Latitude determines how far a location is from the Equator; sun rays are directly concentrated at the Equator, resulting in warmer temperatures which gradually cool as you move away.
- Altitude measures height above sea level; higher locations are typically colder due to decreased warming from Earth's surface.
Additional Climate Concepts
- Maritime Climate characterizes areas near the sea, known for minimal temperature fluctuations; the ocean keeps coastal regions warmer in winter and cooler in summer.
- Ocean Currents are significant water flows in oceans; warm currents travel from tropical regions toward poles.
- Prevailing Winds are common wind patterns; winds from tropical areas bring warmth, while polar winds introduce cool conditions. Winds that cross oceans generally bring precipitation, whereas dry land winds remain moisture-free.
Atmospheric Phenomena
- Depression refers to a low-pressure area, formed when warm, moist air meets cool, dry air. These air masses do not mix due to temperature differences.
- Anticyclones are high-pressure systems made of cool, dry air which sinks and warms, leading to clear, dry weather since clouds are often absent.
Influence on the British Isles
- The British Isles experience depressions due to the collision of warm, moist Atlantic air with cool, dry continental air, forming large systems that take days to pass.
- Anticyclones occasionally affect the region when dry air masses from Europe or North Africa move over Britain.
- The British Isles maintain a temperate maritime climate, characterized by warm, wet summers, and mild, wet winters. Weather is primarily influenced by Atlantic frontal depressions.
