What is a Hurricanes intensity rated by?

What causes derecho?

It all has to do with something called a downburst. When the wet air in a thunderstorm meets the drier air surrounding it, the water in the air evaporates. When water evaporates, it cools the air around it. Derechos happen when the right conditions for downbursts occur over a wide area.
