Definitely a tornado. A hurricane produces a large pressure drop over a distance of hundreds of miles.
A tornado produces a similar, possibly larger pressure drop over only a few hundred feet.
Both a hurricane and a tornado have centers of intense low pressure.
A tornado, most likely. However, few pressure readings have ever been taken from tornadoes.
When a Hurricane, Tornado or Thunderstorm, approaches, the barometric pressure falls but I would not ascribe the adjective "drastic" to this.
No. While they are both spinning storms, tornadoes, unlike hurricanes, can and frequently do form over land.

An object that is placed vertically on a plane will have the steepest pressure gradient. Placing an object on an inclined plane will reduce the pressure it applies downwards.
No. A tornado produces the steepest pressure gradient of any weather phenomenon. An intense mid-latitude cyclone might have an overall pressure deficit comparable to a weak tornado, but that pressure gradient is spread out over several hundred miles. A tornado produces at least that much of a pressure drop over only a few hundred feet.
Both a hurricane and a tornado have centers of intense low pressure.
A tornado produces a greater pressure drop over a shorter distance than a hurricane.
Both produce intense low pressure.
The wind in a tornado moves in a circular fashion as it is pulled inward by the pressure gradient force resulting from the low pressure at the center of the tornado.
Winds spiral in toward the low pressure center of a tornado an build up great speed due to this pressure gradient. However, as they get into the outer part of the tornado's core they are actually spinning so fast that the low pressure cannot pull this air in any further. So the air at the center remains relatively calm. A similar phenomenon is what creates the eye of a hurricane.
Tornadoes and hurricanes both produce low pressure.
No, a hurricane is not a tornado over water. A tornado and a hurricane are quite different. A hurricane is a large-scale self-sustaining storm pressure system, typically hundreds of miles wide. A tornado is a small-scale vortex dependent on a parent thunderstorm rarely over a mile wide. A tornado on water is called a waterspout.
Pressure Gradient Force. which drives the destructive winds.
Yes. The winds of a tornado carry an enormous amount of force. That is why they are so destructive. The winds themselves are driven by a pressure gradient.
The barometric pressure at a tornado is very low, just like in a hurricane. It is also believed that many tornadoes have a relatively calm center where ari descends. This is similar to the eye of a hurricane.
