Answer 1

1. Temperature
2. Relative humidity
   3.clouds
3. Precipitation
4. Air pressure
5. Wind

Question 2

What are the factors affecting Temperature?

Answer 2

1. Latitude
2. Altitude
3. Distance from the sea
4. Cloud cover

Question 3

Types of rain?

Answer 3

Conventional- influenced by temp on ground
Relief - influenced by the terrain

Question 4

What is classified as high and low Rainfall?

Answer 4

High- 1 500 mm of Rainfall n above
Low - below 250 mm of Rainfall

Question 5

What are the characteristics of an equatorial climate?

Answer 5

1. High mean annual temp (20-30)
2. Small annual temp range under 5
3. High total annual Rainfall (>1000 to >2000mm)
4. High HR thru out the year (over 80%)

Question 6

What are the characteristics of monsoon climate?

Answer 6

1. High mean annual temp (but less than equatorial climate)
2. High annual precipitation (1000-2000)
3. High lvls of Rainfall during wet season but much lower lvls during dry season
   4 RH is over 80% during wet season, moderate during dry season

Question 7

What are the characteristics of cool temperate climate?

Answer 7

1. Moderate mean annual temp (10-15)
2. Large annual temp range (abt 25), with 4 seasons
3. Low to moderate annual precipitation (300-900mm)
4. Low monthly precipitation thruout Yr, no distinct wet/dry
5. Moderate RH (70-80)

Question 8

What is used to record temperature?

Answer 8

1. Thermometer
2. Stevenson screen

Question 9

What is used to find RH?

Answer 9

Sling psychrometer

Question 10

What is used to measure precipitation

Answer 10

Rain gauge

Question 11

Equipment to measure wind speed?

Answer 11

Anemometer

Question 12

Instrument to measure wind direction?

Answer 12

Wind vane

Question 13

Instrument to measure air pressure?

Answer 13

Barometer

Question 14

How does air move? (High to low or low to high?)

Answer 14

Higher pressure to lower pressure

Question 15

How does latitude affect Temperature

Answer 15

Thr temperatures decrease as the latitude increases. This is due to a smaller angle of incidence causing the energy to be more spread out thus the temperatures decrease

Question 16

How does cloud cover affect the temperatures? (Presence of clouds)

Answer 16

During the day, large portions of the sun’s energyis reflected back to space. Clouds absorb heat from earth’s surface,thus at night the trapped heat keeps earth surface warm

Question 17

How does cloud cover affect temp? (Absence of clouds)

Answer 17

No clouds results in large amt of the sun’s energy reaching the earth, causing the surface to heat up quickly. At night, with no clouds allows more heat to be radiated from earth’s surface n escape to space, causing cooler temps

Question 18

How does altitude affect temp??

Answer 18

-temp decreases w altitude
-short wave radiation, 45 percent is absorbed by surface
-long wave radiation, surface admits heat, further up u go, further from surface
- air closer to surface aborbs more LWR
- air is less dense higher, traps less heat

Question 19

Does distance from sea affect temp

Answer 19

Yes

Question 20

Relative humidity formula percentage

Answer 20

Act amt of water vapour in air divide by max amtof water vapour the air can hold x100%
