It's hotter there.
Tropics
Tropical air is warm and moist due to high sea water evaporation. Polar air is cold and dry due to less evaporation taking place. Any rain is likely to fall as snow in the polar regions.
there is more energy available to support more organisms in the tropics
there is more solar energy available in the tropics than in the temperate zones.
You would find it in the north tropics
Tornadoes can happen in the tropics but they are more common in temperate latitudes.
There is much more rainfall in the tropics than in the desert which supports a greater number and variety of plants.
the second one
