- Why do saturated parcels cool faster
- WALR cools slower because of latent heat from condensation
- Anticyclone
- High pressure system associated with fair weather
- Mature
- strong updraft, induced downdraft, anvil top
- Dissipating
- Downdraft begins to dominate
- Hurricanes
- Circulation around a deep low pressure center, most damage due to storm surge
- Occluded Front
- Occurs when cold front catches up with a warm front
- LCL
- Ta=Td, parcel becomes saturated, clouds form
- Return Stroke
- Positive charge drains from ground to cloud
- Input > Output
- Surplus
- Causes for climate change
- volcanic eruptions, asteriod impact, solar variability, variation in earth's orbit, continental drift, ocean circulation change
- Air mass t-storm
- short-lived, isolated, weak
- Zone of Aeration
- holds soil moisture
- Characteristics of a sinking parcel
- Stable, Warmer
- Output
- Evapotranspiration
- Super cell
- large, long-lived, rotating storm
- Confined Aquifers
- impermeable layers above and below
- DALR
- 5.5 degrees/1000 ft
- ITCZ
- form Tropical Rainforests
- Characteristics of a stable atmosphere
- Saturation, Cloud formation, (H) Pressure
- Zone of Saturation
- holds ground water
- Microburst
- Intense downdraft becomes localized creating circular damage with 100mph winds
- Input
- Precipitation
- Unproven cause for climate change
- CO2 emissions
- 4 Lifting Mechanisms
- Convergence, Convection, Orographic, Frontal
- WALR
- 3 degrees/1000 ft
- Developing
- Towering cumulus, updrafts
- Adiabatic Process
- No energy exchange, just lifting
- Occluded Front
- Boundary between two polar air masses
- Subtropical High
- form deserts
- 4 Air Mass Types
- cP, cT, mP, mT
- Tornados
- Move to NE, Directional Wind Shear, Intense (L) Pressure
- Stepped Leader
- From cloud to ground, usually faint, invisible - negative charge
- Convection lifting
- due to surface heating
- ELR
- Change in environment's temperature with height
- Charge Seperation
- Friction between rising and sinking hail and water
- Wider the tree rings
- More growth
- Warm Front Characteristics
- Stratus, Slow, Widespread, S Winds, High humidity
- 3 ingredients for a thunderstorm
- instability, moisture, lifting mechanism
- Characteristics of a stable atmosphere
- Parcel warmer the ELR, Rising Motions, Adiabatic Cooling
- Life cycle of a thunderstorm
- Developing, mature, dissipating
- 5 Climate Controls
- Latitude, Altitude, Topography, Continentality, Prevailing Circulation
- Flat line on a climograph
- the more maritime the climate
- Urban rates
- low infiltration, high overland flow
- Where the most evaporation, condensation, precipitation occurs
- Over the Ocean
- Thunder
- Rapid expansion and contraction of air
- Orographic lifting
- windward side of the mountain
- Hail
- occures in the mature life cycle in the top of cloud below freezing
- Cold Front Characteristics
- Cumulus, Rapid, T-Storms, NW Winds, Low humidity
- Flordia's Climate Classification
- Humid Subtropical (Cf)
- Lightning Parts
- Charge Seperation, Stepped Leader, Return Stroke
- Characteristics of a rising parcel
- Unstable, Cooler
- Field Capacity
- Amount of moisture that can be held in the soil
- Stationary Front
- Seperates two non-advancing air masses
