Study Notes
- The cycling of water through Earth's systems is driven by energy from the sun and gravity
- Motions and interactions of air masses influence changing weather conditions
- Unequal heating and Earth's rotation cause atmospheric and oceanic circulation patterns, which create regional climates
Key Terms
- Latitude: Coordinate specifying the north–south position of a point on the Earth's surface
- Longitude: Coordinate specifying the east–west position of a point on the Earth's surface
- Direct Sunlight: Solar radiation that travels straight to the Earth's surface
- Indirect Sunlight: Solar radiation that is scattered or diffused before reaching the Earth's surface
- Heat Capacity: The amount of heat required to change an object's temperature by a certain amount
- Altitude: The height of an object or point in relation to sea level or ground level
- Prevailing Winds: Winds that blow predominantly from a single general direction over a particular point on the Earth's surface
- Convection Current: A current in a fluid that results from convection
- Thermohaline Current: A part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes
- Ocean Conveyor Belt: A global-scale circulation pattern in which density-driven forces and gravity combine to sink cold, salty water in the North Atlantic and then return warmer water to the surface in other parts of the ocean
- Rain Shadow: A dry area on the leeward side of a mountainous area
- Precipitation: Any product of the condensation of atmospheric water vapor that falls under gravity
- Condensation: The change of the physical state of matter from gas phase into liquid phase
- Evaporation: The process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure
- Glaciers: A slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles
- Fronts: A boundary separating two masses of air of different densities, and is the primary cause of meteorological phenomena
Weather vs. Climate
- Weather is the state of the atmosphere at a specific time and place
- Climate is the average weather conditions in a place over many years
- Climate is what you expect, weather is what you get
Thermal Energy Transfer
- Thermal energy transfers through conduction, convection, and radiation
- Thermal energy transfers from warmer to cooler objects
Water Cycle
- Water changes state between liquid, solid (ice), and gas (water vapor)
- Energy flows during the water cycle, e.g., evaporation requires energy input
- Pressure and density change as water moves through the cycle
Latitude
- Latitude influences weather, as it affects the angle of sunlight and temperature
Prevailing Winds
- Prevailing winds are driven by pressure gradients and the Coriolis effect
- Prevailing winds impact weather by distributing heat and moisture
Ocean Currents
- Ocean currents are driven by wind, density differences, and the Earth's rotation
- They impact weather by transporting heat
Heat Capacity
- Land and sea breezes are affected by heat capacity: Land heats and cools faster than water
- Relationship between temperature, density, and pressure influences these breezes
Altitude
- Altitude impacts temperature; temperature decreases with increasing altitude
- Higher altitudes are generally cooler due to lower air pressure
Mountains
- Mountains impact weather by forcing air to rise, leading to cooling, condensation, and precipitation
- Mountains create rain shadows on their leeward sides
Temperature Relationships
- Temperature's relationships with other variables: arrows to indicate increase/decrease:
- Temperature increase = altitude decrease
- Temperature decrease = altitude increase
Fronts
- Fronts are boundaries between air masses: Cold fronts, warm fronts, stationary fronts, occluded fronts
- Different types of weather are caused by fronts, e.g., storms, drizzle
Pressure Systems
- Pressure systems impact fronts: Pressure influences their movement and intensity
