What are the three major types of severe weather? Describe at least two characteristics of each type.
High winds- wind speeds as low as 23 knots (43 km/h) may lead to power outages when tree branches fall and disrupt power lines. Once wind exceed 135 knots (250 km/h) within strong tropical cyclones and tornadoes, homes completely collapse, and significant damage is done to larger buildings. Total disruption occurs once wind exceeds 175 knots (324 km/h) Tornado- Typically look like a narrow funnel reaching from the clouds to the ground. Their wind speed goes from 65 to 250 miles per hour. wildfires- Their behavior depend on factors such as fuel type, moisture content in the fuel humidity, windspeed, topographic and geographic location. They have a rapid forward rate of spread (FROS) When fueled by dense uninterrupted vegetation, particularly in wooded areas with canopies.
