Friday, September 25th 2020, 11:32 am - Hurricanes are dangerous and destructive storms. Here are seven facts about them you may not have known.
We're in the midst of what has been a very active Atlantic hurricane season. As of September 24, there have been eight hurricanes, two of them being major storms. Current damages are estimated at more than $22 billion USD, and there are still weeks to go before storm activity dies down.
Hurricanes are dangerous and destructive storms that form over warm ocean waters.
When the moist, warm air that's over the water rises, it's replaced by cooler air when then starts to warm and rise -- generating a cycle that can lead to the formation of storm clouds. The system could start to spin and become an organized system. If that occurs, the storm clouds and wind speeds will grow stronger, which could lead to the formation of a hurricane.

IMPACT ON NATURE AND THE ENVIRONMENT
- "Hurricanes not only transport heat from the warmer tropics towards the colder polar regions (a vital part of Earth's climate system), but they also help radiate tropical heat out into space." -- Scott Sutherland

- "Despite their huge size and destructiveness, hurricanes are a small part of the planet’s energy transfer and they are just an expression of heat being moved from the equator towards the poles." -- Mark Robinson

- "Birds occasionally get trapped by hurricanes and will seek shelter in the eye of the storm, where the winds are astonishingly light. Over Florida in 2016, radar images of Hurricane Matthew showed a huge flock of birds stuck in the eye, which they, unfortunately, had no choice but to be carried northward with the storm, becoming displaced by thousands of kilometres." -- Erin Wenckstern
- "In 1979, Typhoon Tip was a unique beast, taking the record for not only the lowest pressure ever recorded in a tropical cyclone (870 mb), but also the largest with a diameter of 2200 km (1380 miles), able to cover Ontario twice!" -- Erin Wenckstern

- "The largest hurricane/typhoon ever recorded was Typhoon Tip in the Pacific in 1979. It had a wind diameter of 2200 km and a max wind speed of 305 km/h. At its largest, Tip was nearly half the size of the contiguous United States." -- Mark Robinson
