Latent heat is …

Is ‘hidden energy’ heat energy is released or absorbed to change the state of a substance whiteout changing temperature

Advection is …

1. Is a transfer of energy by horizontal movement of the air

2. Advection occurs whenever the wind blows

Conduction is …

Is the transfer of heat energy through direct physical contact between two bodies or substances

Solar radiation is a ? and ? Wave

1. intense

2. Short

Terrestrial radiation is a ? intensity and ? Wave radiation

1. Low

2. Long

An inversion

Describes a temperature increase with altitude ( warm air is aloft )

Examples include ~ ground inversion, subsidence inversion, turbulent inversion, frontal inversion and valley inversion

Ground inversion is …

are formed either at night as the surface layers cool, or at other times by warmer air moving over a cooler surface

Subsidence inversions is …

Are common in high pressure areas, where the descending dry air warms faster than the static environmental air

Frontal inversion is …

Form when warm less dense air flows and up over cooler, denser air

Friction layer inversion is …

Is created by a turbulent mixing modifying the surface layer lapse rate

Valley inversion is …

Are formed art night when colder denser air sinks and pools in the valley, displacing warmer air aloft

What is isotherm

Constant temperature

What is a radiosonde

1. Battery powered telemetry instrument carried into the atmosphere via a weather ballon

2. Tests are done on none busy days

3. Measures vary atmospheric parameters

4. Transmits the information by radio

Valley inversion can cause …

Wind shear or turbulence ~ THINK OF GIBRALTER

This is because of a change in density
