Extreme Wind
Air travelling at high speeds can cause direct and indirect damage to a property’s external structures such as roof, walls or windows.

Effects of Climate Change on Extreme Wind

Increased temperatures associated with climate change in turn increases the moisture in the air and can change convective forces in storms and the severity of air currents.
Changes in Humidity
Higher temperatures result in higher rates of evaporation from the land and sea. This change in humidity shifts weather patterns and winds.
Dryer Conditions
As temperature and humidity levels rise and fall in new patterns, convective currents also change, bringing stronger and unpredictable winds.

Contextual Data

Climate Risk Engines looks at how wind patterns are changing and predicts the probability of extreme wind occurring in the future. As convective currents shift with climate change, some areas may be more at risk than others. Properties in areas that have physical hazards such as tall trees and those that have historically experienced extreme wind events are often more at risk.
Local Weather Patterns
Areas that have historically experienced strong winds are likely to be impacted.
Nearby Physical Hazards
Physical hazards near the property that may be blown over or broken in the wind (such as trees) can cause blackouts and property damage.

Asset Data

The resiliency of a property to extreme wind events is determined by what year the building was built and the National Building Codes that were present at the time. Older buildings are often not built to withstand intense wind speeds and these buildings also deteriorate over time, leaving them more vulnerable to damage. As performance guidelines have been adjusted, modern home designs are typically less vulnerable, while some properties may increase their resiliency to protect themselves against specific wind thresholds.

Climate Valuation looks at the variables of a property (e.g. orientation, year of build, materials, and location) to determine the predicted impacts of extreme winds and level of risk in that area. Properties built with aerodynamics (how air moves) in mind, fare better when experiencing extreme wind. Characteristics like strong foundations, materials and style of roofing are key to a wind resistant building, stacked roofing disrupts the airflow and reduces the likelihood of significant damage.
