A television meteorologist is able to inform viewers about the intensity of an approaching hurricane. However, the meteorologist can report the intensity of a tornado only after it has occurred. Why is this the case?

The meteorologist can report the intensity of a tornado only after it has occurred because (Tornado intensity is based on damage done.)

Explanation:

HURRICANE is a type of violent storm called topical cyclone which is characterised by a large rotating storm with high speed winds that forms over warm waters in tropical areas. They are form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form. These storm clouds will begin to rotate with the spin of the Earth forming an organized system. If there is enough warm water, the cycle will continue and the storm clouds and wind speeds will grow causing a hurricane to form.

Hurricane can cause alot of damages such as flooding and storm surge. And they are also capable of developing to TORNADO.

The intensity of any tornado that occurred can only be measured through the damage it causes. This is because the correct intensity can only be determined while on site or remote sensing of the tornado which is quite impractical for wire scale use, therefore damages as a result of the tornado is used to quantify it.
