extreme weather/ tropical storms Flashcards
compare extreme temperatures in 2 different countries
-Australia is warmer than the UK
-average summer in Australia is 33 and UK its 23 degrees Celsius
-Australia has lower precipitation
-Australia has stronger extreme winds
-Australia is affected by tropical cyclones
what conditions are required for a tropical storm to develop
when sea temperatures is 27 degrees or higher, there’s lots of warm air to cause extreme precipitation
what is the Coriolis effect
the way the earth’s rotation causes rotating weather systems and tropical storms
how is a tropical storm developed
- when warm air rises and cools releases huge amounts of energy. rising air creating low pressure increases surface winds
- earth’s rotation deflects path of the winds, which causes storm to spin
- storm gets stronger due to energy from warm water so winds speed increases
explain how extreme winds are associated with tropical storms
-strong winds are causes by low pressure at the centre of the storm that creates a big pressure difference
explain how extreme rain are associated with tropical storms
large amounts of warm air is sucked towards the centre of the storm due to pressure difference. Air rises cools and condenses causing rain
what are the extreme weather conditions causes by tropical storms
extreme winds and rain
how has the frequency of tropical storms varied over time
number of tropical storms varies each year, in the Atlantic, number of tropical storms increased since 1984
what do majority of storms occur
northern hemisphere in late summer/autumn, when sea temperatures are the highest
what is the eye wall of the tropical storm
outer edge of the eye with very strong winds
identify 2 hazards associated with topical storms
strong winds, storm surges
