Straight-line Wind

There are several terms that mean the same as straight-line winds and they are convective wind gusts, outflow and downbursts. Straight-line wind is wind that comes out of a thunderstorm. If these winds meet or exceed 58 miles per hours then the storm is classified as severe. the winds produce by the downward momentum in the downdraft thunderstorm. When the National Weather Service does a storm damage survey they distinguish between straight-line wind and wind produced from a tornado. Straight-line wind damage will push debris in the same direction the wind is blowing (hence the creation of the term straight-line). Tornado damage will scatter the debris in a variety of different directions since the winds of a tornado are rotating violently. stright live winds can happen anywhere that there are thunderstorms. Straight-line winds can cause alot of damage. it is simular to tornados due to the high winds and it can harm the enviornment by causing damage.

Technlogoy used to predict straigh line wind are T₁ and T₂ methods. The T₁method is used to predict average maximum gusts and the maximum wind gust in frontal thunderstorms. The method should be used to compute the maximum wind gust in frontal thunderstorm s of in a prefrontal squall line.
