Hurricanes are more powerful than tropical storms. A hurricane, in fact, is a tropical storm until its wind speed increases to at least 74 mph sustained.

Erica's Answer:

Your other question is comparing the power of a hurricane to a tornado. Basing my answer only on the amount of energy that is released in a hurricane, then you can definitively say that a hurricane is more powerful than a tornado. This is because hurricanes are so much larger than tornadoes. Tornadoes are a couple miles wide at the most, whereas hurricanes can be about 1,000 miles in diameter. The wind field, or number of square miles with strong winds, is much larger in hurricanes than in tornadoes. Also, hurricanes aren't just a bunch of wind, like tornadoes are! Hurricanes also carry a lot of water. The combination of wind-driven water makes hurricanes much more powerful than tornadoes!
