2.Magnitude, Regularity and Predictability

Question 1

Saffir Simpson

Answer 1

Developed in 1971 and allows storms of different magnitudes to be compared, absolute scale based on sustained wind speeds, widely used
HOWEVER
Limited value when assessing impact, doesn’t take into account rainfall, or area affected by the storm
Difficult to prepare, extent of damage is unknown

Question 2

Regularity

Answer 2

REGULAR:
Over a long period of time there is a degree of regularity, generally restricted to the tropics and not too close to the equator. Occur in summer to Autumn

IRREGULAR:
No set spatial or temporal pattern. Although they follow similar tracks each storm develops its own characteristics and responds uniquely to atmospheric and oceanographic conditions

Question 3

Predictability

Answer 3

US NOAA publishes a prediction of hurricane activity for upcoming season. Use satellites and supercomputers to analyse sea surface temps, atmospheric conditions and climatic cycles

NOAA cannot predict landfall or give precise locations can only be done in final few days but can still change course
