Tropical storms (& case study typhoon Haiyan) *

Question 1

What is a tropical storm?

Answer 1

a very powerful low pressure weather system that results in high wind speeds and heavy rainfall

Question 2

What is the coriolis effect and how does it effect tropical storms?

Answer 2

the coriolis effect is caused by the earths roation and causes tropical storms to spin

Question 3

What is the central part of a tropical storm?

Answer 3

The eye of the storm - area of light wind speeds and no rain, contains condensing air

Question 4

What is the area surrounding the centre of the storm?

Describe it

Answer 4

The eye wall - large cumulonimbus clouds surrounding the eye, warm moist air condenses as it rises, heavy rainfall and high wind speeds

Question 5

What is the edge of the storm?

Answer 5

The edge of the storm - moderate wind speeds, rainfall and temperature, clouds small and scattered

Question 6

How do tropical storms develop?

Fill the gaps :

form between _ & __ degrees latitude/ north south
occur in early ______ - sea temperature is _______
air above ____ ocean is ______, reaches at least __ degrees C, warm air ____, creates area of very ___ pressure
air draws more ____, ____ air from above the ocean, creates ____ winds
rapidly rising warm air _____, _____ and ________, forming ___________ ______
forms ___ ____, where there is _____ rainfall
in the centre, ____ air _____, forming the eye

Answer 6

form between 5 & 30 degrees latitude / north south
occur in early autumn - sea temperature is highest
air above warm ocean is heated, reaches at least 27 degrees C, warm air rises, creates area of very low pressure
air draws more warm moist air from above the ocean, creates high winds
rapidly rising warm air rises, cools and condenses, forming cumulonimbus clouds
forms eye wall, where there is heavy rainfall
in the centre, cold air sinks, forming the eye
