Wind speeds as low as 23 knots (43 km/h) may lead to power outages when tree branches fall and disrupt power lines. [15] Some species of trees are more vulnerable to winds. Trees with shallow roots are more prone to uproot, and brittle trees such as eucalyptus, sea hibiscus, and avocado are more prone to branch damage. [16]
Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds. The additional trees can also prevent or reduce topsoil erosion (from water and wind), floods and landslides. Finally, additional trees can be a habitat for wildlife, and provide employment and wood products. [2]
The worst-affected areas were communities near the Humber River, Holland Marsh, and Etobicoke Creek. Prone to flooding, the Humber River raced downstream from Woodbridge when an earthen dam failed. In the weeks prior to Hazel, Toronto had received copious amounts of rain, and the soil could not hold as much as 200 mm (7.9 in) of rain ...
Lower temperatures were also recorded at the city’s Yangtze River Beach Park, where 45,000 trees and other vegetation sequester an estimated 724 tonnes of carbon per year.
Atmospheric rivers of the sort causing massive floods and mudslides in Canada's British Columbia are akin to a river in the sky, weather systems that carry up to 15 times the volume of the ...
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
Hurricane-force wind gusts up to 77 mph wreaked havoc in the western part of the state, bringing down numerous trees in addition to power lines. The Seattle area was particularly hard-hit.
The removal of trees at a forest's edge increases the exposure of the remaining trees to the wind. Trees that grow adjacent to lakes or other natural forest edges, or in exposed situations such as hill sides, develop greater rooting strength through growth feedback with wind movement, i.e. 'adaptive' or 'acclimative' growth.
