Our hearts and thoughts go out to those in Texas suffering from Hurricane Harvey.
Tropical rotating storms — hurricanes to us, typhoons and cyclones elsewhere — are not a mystery. They occur in tropical zones between 10 and 20 degrees North and South when ocean temperatures exceed 82 degrees F. They derive their energy from the increasing moisture in the air above the warming oceans. The damage caused by hurricanes results from their energy content, the ocean level and the surge they generate.
