Hurricane,Cyclone & Typhoon . Are they different phenomena

Weather forecasts keep changing all the time,don't they ?  Many Brazilian people never check the weather forecasts before leaving home ,but a lot of foreign people never leave home without listening ,reading or watching information about the weather.

How about you  ? Do you often pay attention to the weather forecast or you do not worry about the weather at all ?

The British anthropologist Kate Fox,who performed the studies in 2010 for an update of her book  "Watching the English-The hidden rules of English Behaviour  " has said  :" According to recent research 94% of British respondents admit to  having conversed about the weather in the past 6 hours while 38% say they have in the past 60 minutes.This means at almost any moment in England,at least a third of the population is either talking about the weather,has already done so or is about to do so !
