Energy transfer Flashcards
An object is said to _______, if it is capable of doing work.
Possess energy
Present activity in the atmosphere may be regarded as _______ energy sources while activity in the past may be regarded as _________ energy sources
Renewable
Non-renewable
What are the internal sources of energy?
Earth’s energy
Earth’s attraction
Earth’s rotation
What are the external sources of radiation?
Solar radiation
Solar and lunar gravitation
Why is solar radiation important?
Provides incoming heat to the earth-atmosphere system.
Why is Solar and lunar gravitation important?
Seasons and monthly cycles
Why is Earth’s heat important?
Tropospheric heating
Why is earth’s gravitation and rotation important?
Vertical pressure distribution, keeps atmosphere in place. day and night cycles
What is kinetic energy
The energy possessed by an object because of its motion
the heat energy of a body depends on the _______ of its particles
Total kinetic energy
Kinetic energy computations can assist in forecast:
- Positions of cloud tops
- wind speeds
- severity of baroclinic systems
State the general law of conservation of mass and energy:
In any system the sum of the mass and energy remains constant.
List the 4 processes by which heat is transferred in the atmosphere
Radiation
Conduction
Convection
Advection
Radiation and conduction transfer energy via:
Heat exchange
Advection and convection transfer energy via:
Mass transfer
