Study Notes
Earth Science - Chapter 12
- Weather vs. Climate: Weather is the short-term state of the atmosphere, while climate is the long-term average of weather variations in a particular area.
Meteorology
- Definition: Meteorology is the study of atmospheric phenomena, originating from the Greek word "meteoros," meaning "high in the air."
High and Low Pressure Systems
- Differences: High-pressure systems are characterized by sinking air, while low-pressure systems are characterized by rising air.
Heating Earth's Surface
-
Imbalanced Heating: Earth's axis tilt causes uneven solar radiation, leading to variations in temperature across different locations and times.
-
Uneven Solar Radiation: Direct sunlight creates more concentrated heat per unit area than diffuse sunlight.
-
Thermal Energy Redistribution: Constant air movement distributes thermal energy globally, forming weather patterns.
Air Masses
-
Definition: Air masses are large volumes of air with consistent humidity and temperature characteristics, originating from a specific source region.
-
Source Regions: Air masses take on characteristics of the land or water they form over. Examples include maritime tropical (warm, moist), continental tropical (hot, dry), maritime polar (cold, moist), continental polar (cold, dry), and arctic (very cold, dry).
Air Mass Modification
- Modification: When air masses travel over different terrains, their temperature and moisture content adjust, leading to modifications in their characteristics. An example is when continental polar air moves over a body of water, it gains moisture, becoming milder. (e.g., lake-effect snow).
Global Wind Systems
-
Coriolis Effect: Earth's rotation influences wind patterns, causing fluids and objects to move in curved paths, rather than straight lines, (Apparent deflection).
-
Polar Easterlies: Winds between 60° latitude and the poles.
-
Prevailing Westerlies: Winds between 30° and 60° latitude.
-
Trade Winds: Winds between 30° latitude and the equator.
-
Intertropical Convergence Zone (ITCZ): Area near the equator where trade winds converge, often characterized by rainfall.
-
Jet Streams: Strong, high-altitude winds that influence weather patterns. Polar and subtropical jet streams are distinguished by their location.
Fronts
-
Definition: Fronts are boundaries where contrasting air masses meet.
-
Types: Cold fronts (cold air displaces warm air), warm fronts (warm air displaces cold air), stationary fronts (neither air mass advances), and occluded fronts (cold air overtakes a warm front) are the four main front categories that directly effect weather patterns.
Pressure Systems
-
High-Pressure Systems : Air sinks, causing generally fair weather.
-
Low-Pressure Systems: Air rises, frequently associated with clouds and precipitation.
