Atpl Weather - Temperature

Front 1

Surface temp dependent on

Back 1

a. Angle of incidence of solar radiation

b. Amount of radiation reflected

c. Type of surface (land, water)

Front 2

Diurnal variation smallest

Back 2

Temperate oceans

Front 3

When air subsides

Back 3

Compressionally heated - relative humidity dec

Front 4

Temp calculations at high altitudes

Back 4

Up to -56.5 C

Front 5

Heat transfer

Back 5

Evaporation - absorbs heat

Sublimation- absorbs heat

Freezing - absorbs heat

Freezing - release heat

Condensation- release heat

Deposition - release heat

*evaporation from growing vegetation or moist soil will reduce heating

Front 6

Relative humidity

Back 6

Ratio determined by comparing actual amount of water vapor in air to amount that would be present if air was saturated at same pressure and temperature

Front 7

Nocturnal LLJ

Back 7

Generally:

- over flat terrain (ex Prairies)

- predominant in Summer

Front 8

Inversion types

Back 8

1. Frontal

2. Subsidence: H

3. Nocturnal

4. Tropopause

Front 9

Evaporation of rain

Back 9

Rain falls into cold air - heat absorbed due evaporation - air made cooler - moisture added - saturation - condensation = St cloud

Front 10

Hoar frost forms

Back 10

Air with blw freezing dp cools to saturation

Front 11

Earths surface heated by

Back 11

Short wave solar radiation

Front 12

Wet bulb reading = dry bulb reading

Back 12

Relative humidity 100%
