Vocab 1
the weather conditions happening in an area in general or over a long period.
What is climate?
the transfer of heat energy through direct contact between the Earth's surface and the air molecules above it, warming the lower atmosphere.
conduction
a pattern of circulation in the atmosphere with associated weather, particularly a recurring pattern of this type.
System
the tendency of the atmosphere to promote vertical air motion.
What is instability?
the mass of air molecules per unit volume
density
all about the atmosphere, including temperature, atmospheric pressure, wind, humidity, precipitation, and cloud cover.
What is weather?
the weight of the air above a given point
What is air pressure?
a short-term balance between incoming and outgoing energy.
What is equilibrium?
the movement of energy from one place to another through - radiation, conduction, and convection.
energy transfer
an instrument used to measure atmospheric pressure
What is a barometer?
a region where air pressure is greater than the surrounding areas, typically leading to stable, clear, and fair weather due to sinking air.
What is high pressure?
a weather area where the atmospheric pressure is lower than the surrounding area. This causes the air to rise, cool, and condense into clouds and precipitation.
What is low pressure?
a body of air with horizontally (side to side) uniform (similar) temperature, humidity, and pressure.
What is an air mass?
a boundary between two air masses of different densities, temperatures, and moisture levels.
What is a front?
the vertical (up and down) movement of heat and moisture in the atmosphere, caused by differences in temperature.
convection
the upward movement of air
What is lift?
atmospheric conditions that can greatly impact the environment, such as storms, heatwaves, heavy rainfall, hurricanes, tornadoes
What is an event?
