Why do tropical hurricanes need ocean temperatures of at least 80 degrees to form?
Tropical hurricanes can form at temperatures of less than 80 degrees but become more powerful when the water temperature is higher. When the wind from a hurricane sweeps across warm ocean water it evaporates easily. When that water vapor rises and turns back into rain, it gives off 540cal/g. That produces the energy that produces the wind that drives the storm. When the water is cooler, the storm has less energy that it can pull from the water. When a storm sits still over an area, it cools down the water and loses strength.
What are hurricanes and how do they form?
A hurricane is a storm. Conditions must be right for them to form in the tropic water (Ocean temperatures must be over 80 degrees F. , warm wind is needed.)
Do temperatures increase or decrease when a storm is coming?
Decrease

What temperature does the air have to be for a tornado to occur?
There is no exact temperature. especially since many tornadoes form in storm generate by cold fronts where the temperature changes fairly quickly. However they generally require warm temperatures and rarely form in temperatures of less than 60 degrees Fahrenheit.
