Chapter 2 - Temperature

Question 1

Give Kelvin and Fahrenheit at 0 Degrees

Answer 1

273 Kelvin

32 Fahrenheit

Question 2

How do we measure the surface temp

Answer 2

Stevensons Screen

4 feet off the ground / 1-2m

Question 3

How do we measure the upper air temp

Answer 3

Weather ballon’s with Radiosnodes measuring Px, temp, altitude, humidity

Question 4

What does insolation mean

Answer 4

Heat created on the surface caused by the Sun

Question 5

Why hotter on the Equator

Answer 5

The sun rays are more concentrated

Question 6

What is the name of the heat and source of long and short waves?

Answer 6

Short Waves = insolation from Sun

Long Waves = Terrestrial from the surface

Question 7

Another word for reflectivity

Answer 7

Albedo

Question 8

What has a high specific heat

Answer 8

Water - slow to heat and cool

Question 9

What has a low specific heat

Answer 9

Land - quick to heat and cool

Question 10

What causes green house effect

Answer 10

Water & CO2

Question 11

What is conduction

Answer 11

Transfer of heat between physical contact. The Earth’s surface to air

Question 12

What is Convection

Answer 12

Transfer of heat vertically

Question 13

What is Advection

Answer 13

Transfer of heat horizontal

Question 14

Give the process to the atmosphere from WV to W to Ice plus the stages

Answer 14

Warming process - Latent heat released
Condensing
Freezing

Question 15

Give the process to the atmosphere from Ice to W to WV plus the stages

Answer 15

Cooling Process - Latent heat absorbed
Melting
Evaporation

Question 16

WV to Ice each way is called

Answer 16

Sublimation

Question 17

What can cause the Diurnal temp range to be smaller

Answer 17

Wind and Clouds

Question 18

When the ground cools the air directly above it with no convection

Answer 18

Called Ground/ Nocturnal/ Radiation Inversion

Question 19

In a valley Inversion what is the downslope wind called

Answer 19

Katabatibc effect

Question 20

What is a frontal Inversion

Answer 20

Warm sea air being blown towards cool land

Question 21

Discribe a Subsidence Inversion

Answer 21

At a fixed point higher Px air pushes outwards, creating a pocket for cold air, the warm sinking air then sits on top

Question 22

What is the heat equator

Answer 22

Because of the angle the earth sits the heat equator is different to the geographical one. Also called ITCZ and varies with the time of year.
