2 climate blog

Hurricanes-These are tropical storms that have a low pressure center. They cause high winds and precipitation. Their strength is increased over warmer waters. With global climate change the water is getting warmer and therefore the hurricanes are becoming more powerful than they used to be.

Tornados-These are violent wind vortexes that are often seen with debris around them. They are caused by mesoclones. These are created by low pressure and wind rising at the same time. The tornados have been seen on every continent except anarctica but mostly occur in the U.S. and mostly in tornado alley in the U.S.
