Eye cyclone Diagram of a Northern hemisphere hurricane Tropical cyclones are areas of relatively low pressure in the tropospherewith the largest pressure perturbations occurring at low altitudes near the surface. On Earth, the pressures recorded at the centers of tropical cyclones are among the lowest ever observed at sea level. As air flows radially inward, it begins to rotate cyclonically counter-clockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere in order to conserve angular momentum. At an inner radius, air begins to ascend to the top of the troposphere.
If you live near the coast, know what the local tides are. High tides will significantly increase the danger from storm surges. Go indoors and remain indoors during a hurricane. A battery-operated radio will ensure your access during power outages.
Winter Severe Weather Blizzards The word blizzard was first used to describe a snow storm in the early nineteenth century in the United States. Blizzards combine high winds, bitter cold and blowing snow.
They are dangerous on several counts. First, the snow is often powdery and fine enough for you to breath into your lungs. Second, the combination of bitter cold and high winds can cause frost bite within seconds.
And third, the blowing snow and high winds often reduce visibility to almost zero. Canadian literature abounds with true stories of pioneers, farmers, ranchers and explorers who froze to death only metres away from the shelter they could not see.
In Canada, blizzards are most common in the southern Prairies, the Maritimes and the eastern Arctic. They are relatively rare in Ontario. Freezing Rain Freezing rain is a significant winter hazard in Canadabut can also occur in late fall or early spring.
Freezing rain glazes trees, hydro lines, roads and sidewalks with ice. Buildups of ice can bring down branches and trees as well as overhead power and telephone lines. This can disrupt power supplies and communications for days. Even a small accumulation of ice may pose a risk to both pedestrians and drivers.
If you must go outside for a short period, dress in multiple layers of loose-fitting clothing. Outer clothing should be hooded, tightly woven and water repellant. Mittens are warmer than gloves. Wear a hat, because most body heat is lost through the head.
Never touch a power line that may have come down due to wind or ice buildup. It may still be "live" and you could be electrocuted. If you become stranded while traveling in a vehicle, wait for rescue: Keep dry and warm.
If you begin to sweat, remove your hat or one layer of clothing. Keep fresh air in the car by opening the window one centimetre or less on the side away from the wind.
Exercise your arms and legs periodically to keep your hands and feet warm. Keep watch for traffic or for search parties. Ice Storm is a term used to identify particularly severe freezing rain events.
The ice storm which hit parts of eastern OntarioQuebec and New Brunswick from January 4 to 10,was the worst in recent memory. The storm was directly or indirectly responsible for the deaths of 25 people. At its height, the storm left nearly three million people in Quebec and Ontario without electricity or heat.
A week after the storm ended, nearly one million people were still without light or heat. Ask your students to write a story describing what it would be like to live in their homes for seven days in the winter without electricity, running water adn heat from the furnaces.
Ask them what supplies they might want to keep on hand to help cope with such an event. In some respects that storm was typical of most freezing rain storms. For several days a low pressure area over the Texas panhandle pumped warm, moist air from the Gulf of Mexico into southern Ontario and Quebec.Application Case: Tropical Storm Wilma 1.
