How do hurricanes form? A lesson in the science behind the storm – The Globe and Mail

What are hurricanes?Hurricanes are part of a family of storms called tropical cyclones – storms that rotate rapidly around a low-pressure centre and produce heavy rain and strong winds. If one of these storms hits a sustained top wind speed of 119 kilometres an hour and appears in the Atlantic or eastern North Pacific, it qualifies as a hurricane. (Similar storms in the western North Pacific are called typhoons.) The Saffir-Simpson hurricane wind scale goes up from there, through to Category 5, which has no ceiling and represents storms with wind speeds greater than 252 km/h. Anything from Category 3 and up is a “major” hurricane.

Fighting climate change while encouraging innovation and productivity is part of the government’s plan to grow the economy and create jobs. An important part of this plan is creating a low-carbon economy through a cap and trade system, which will limit pollution, reward innovative companies and create more opportunities for investment in Ontario.
