Challenges of Natural Hazards: Tropical Storms Flashcards
What conditions do TROPICAL STORMS need to form?
Tropical waters above 27oc
Forms in SUMMER and AUTUMN when sea temperatures are at its’ highest
Where do TROPICAL STORMS FORM?
5-15oN&S of the equator
Describe how air effects TROPICAL STORMS
Air gets drawn into the ‘EYE’
Warm air rises up and cools which condenses to form clouds
15k-20km above sea level winds spiral outwards
What are some KEY STRUCTURES of TROPICAL STORMS?
Storm has a central ‘EYE’- relatively calm in the centre
‘EYE’ wall has the strongest winds and rainfall
What are some CHANGES of TROPICAL STORMS overtime?
Sea temperatures in TROPICS have risen- areas where TROPICAL STORMS occur have grown e.g. Hurricane Catarina affected Brazil
Frequency of TROPICAL STORMS have decreased
However intensities of TROPICAL STORMS have increased- due to increase of sea temp
