Q

How does air temp work in relation 2 rotation of Earth?

A
  1. earth rotate, side face Sun, day, recieve solar radiation, experience higher temp
  2. side eventually face away, rotation, dosent recieve solar radiation experience night time, experience lower temp

16
Q

Midday
1. sun position
2. solar radiation
3. temperature

over year
revolutions + seasons

A
  1. directly overhead
  2. smaller surface area hit, more concentrated
  3. highest of whole day

SG

23-25-31-33

17
Q

before, after midday
1. sun position
2. solar radiation
3. temperature

A
  1. not directly overhead
  2. larger surface area hit, less concentrated
  3. lower than midday

SG

23-25-31-33

18
Q

before sunrise
1. sun position
2. solar radiation
3. temperature

aka night

A
  1. does not recieve solar radiation, loses heat for longest time, form of longwave radiation
  2. lowest

SG

23-25-31-33
longwave radiation emitted from ground

19
Q

air temp variations (year) cause

aka seasons

A
  • earth revolution arnd sun
  • 23.5deg Earth axis tilt
  • hemispheres recieve diff amt solar radiation across yr
20
Q

Template for Temperature at different seasons.

A
  1. At month, N/S/Neither Hemisphere
    leans towards Sun
  2. higher/lower direct solar radiation
  3. experience hotter/colder/moderate temp
  4. NH (spring/autumn), SH (autumn/spring)

Step 2 if Summer/Winter
Step 4 if Autumn/Spring

21
Q

relative humidity calculation

A

Amt water vapor (g)/(max cap water (g) air can hold at that temp) * 100%

22
Q

Rh accurate indication of moisture in air/rainfall?

A

Rainfall
- Rh also affected by temp,
- when Rh = 100%, about 2 rain

i.e. Rh = 100%
Summer, hotter, air more water capacity: 60 Arbitary unit
Winter, colder, air less water capacity: 10 Arbitary unit

23
Q

1 type of cloud in syllabus

A

Culmulonimbus clouds
