Vocab 1
the weather conditions prevailing 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 immediately 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
the state of the atmosphere, including temperature, atmospheric pressure, wind, humidity, precipitation, and cloud cover.
What is weather?
the weight of the air above a given point, which exerts force on the Earth's surface
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 air pressure?
a weather area where the atmospheric pressure is lower than the surrounding areas, causing air to rise, cool, and condense into clouds and precipitation.
What is low pressure?
a body of air with horizontally uniform 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 transport 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 significantly impact the environment, such as storms, heatwaves, and heavy rainfall.
What is an event?
