The tables below represent rainfall and temperature of stations X and Y. Use them to answer questions (a) and (b)

KCSE Geography Paper 1 2003 Section B Question 8.

The tables below represent rainfall and temperature of stations X and Y. Use them to answer questions (a) and (b)

a) (i) for each of the two stations calculate the mean annual temperature.​

• X - 31- 28= 3C
• Y -  12-12=9C

​(ii) Calculate the annual rainfall for station Y

• The station received low rainfall
• Rain falls throughout the year
• The wettest month is June/the driest moth is February
• Summers are relatively dry while winters are relatively wet
• Most rain falls between May and August
• The station experiences warm summers and cool winters
• Temperature’s are moderate throughout the year

​(iii) On the graph paper provided, draw a bar graph to represent rainfall for station x. Use vertical scale of 1cm to represent 50mm

​b) Describe the climatic characteristics of station Y.

• water surface/sea is heated intensely by conduction
• Maximum heating occurs in the afternoon
• Moisture laden air rises in conventional currents
• As the warm air rises, it is cooled
• The moisture laden air condenses at high altitudes
• The condensed water vapour forms clouds which develop into cumulonimbus clouds with time
• The clouds give rise to heavy/torrential rain accompanied by thunder an lighting and sometimes hail stones

​c)(i) Describe how conventional rainfall in the lake region of Kenya

• The torrential rains cause floods which displace people
• The hailstones destroy crops
• The strong winds blow off roots of houses/ uproot trees
• Lightning strikes causing deaths of people and animals
