[Music] hurricanes typhoons and Cyclones are tropical storms they are essentially the same but are labeled differently depending on which region of the world they occur in hurricanes form in the North Atlantic and Northeast Pacific Oceans largely affecting the Caribbean islands and the US Cyclones emerge in the South Pacific and Indian oceans while typhoons begin in the Northwestern Pacific paciific ocean these tropical storms begin when a group of rain showers and weak thunderstorms form when Waters get warmer warm Waters heat the air causing it to rise quickly as it cools more warm air rises creating a strong wind spiral winds in the spiral increase to speeds over 117 kmph this coupled with warm water fuels the growth and movement of the Spiral storm the storm weakens and dissipates when it hits cooler water or land hurricanes are categorized on a scale of 1 to 5 by their wind speed using the suffer Simpson hurricane wind scale category 1 is considered dangerous and will produce some damage winds in these can reach up to 153 kmph category 2s carry winds up to 177 kmph and can cause extensive damage Category 3 and above are considered major hurricanes category 3's pack winds up to 208 kmph and category 4S reach 251 kmph devastating damage and even loss of life occur when these make landfall the deadliest are Category 5 with wind speeds exceeding 252 kmph these bring catastrophic damage and destruction to anything in their path [Music] Cyclones are also categorized by wind speeds using the suffer Simpson hurricane wind scale seasonal Cyclones form between November and April and largely affect countries in Africa and Asia typhoons form from May to October but can occur throughout the year too they impact Far Eastern countries like Japan and the Philippines typhoons are also measured using the Safir Simpson hurricane wind scale with the most severe being super typhoons hurricanes Cyclones and typhoons are given names for easier identification weather scientists meet once a year in their regions to choose new names names are selected in alphabetical order and the lists are sent to weather bureaus in the regions that are commonly affected names of exceptionally destructive storms are retired and never used again
