Weather wise, we point to Florida's lack of winter ...
As what separates it most from the continental north.
Spring and fall is where the true contrast lies.
Continental stream systems peak in spring (sometimes as is the case for the Red River with record floods) and ebb to their low flow condition (called base flow) in fall. The exact opposite is true for the flow ways of the south Florida peninsular swamp:
Fall marks peak flood season and spring is a time of drought.
Then there's the story of south Florida's famous "wrong way" clouds. I'll save that for another day.
