A common way supercell thunderstorms gain their rotation is from wind shear. Which of the following is an example that has BOTH speed and directional wind shear? - ️️Surface wind: SW 5mph; 5,000 ft. wind: SE 25mph. A dryline causes uplift to occur because - ️️the lifted air mass is moister and less dense than the intruding air mass. A large percentage of structural damage and coastal flooding from tropical storms and hurricanes can be attributed to - ️️storm surge. A main feature ...
