thunderstorms in urban areas

Question 1

where they devlop

Answer 1

in hot humid air and characterised by violent and heavy precipitation

Question 2

formation of thunderstorms

Answer 2

• heating of air causes uplift which causes it to rise
• the air cools rapidly causing condensation and clouds to form
• this results in towering cumulrumbus clouds
• rapid cooling leads to the formation of water droplets
• raindrops are split in the updraught causing positive enrgy to build up
• this charge builds up and released to areas of negative change to cause lightning
• thunder occurs as a result of a sudden increase in pressure and temp to produce rapid expansion of air surrounding it

Question 3

link between thunderstorms and urban form

Answer 3

• urban areas 1-3 degrees warmer than surrounding area to cause rapid evaporation from more humid air
• updrafts of unstable air due to buildings which increases conventional uplift of hot humid air causing it to rise
• urban areas generate dust and pollution- this acts as condensation nuclei which encourages clouds to form
