Hurricanes are driven by low pressure. Low pressure pulls in warm, moist air, leading to convergence in the lower atmosphere, this causes thunderstorms to spring up, which lower the pressure further and pull in more warm, moist air. These processes help to sustain one another in a hurricane.
Yes, barometric pressure decreases significantly in the midst of a hurricane. This drop in pressure is one of the key indicators of the strength of a hurricane, with lower pressure correlating to a more intense storm.
The decrease in millibars indicates a drop in atmospheric pressure, which correlates with the increasing intensity of a hurricane. A lower pressure system allows air to rise and fuels the storm's development and strength. Conversely, an increase in millibars signifies a rise in atmospheric pressure, which can weaken the hurricane.

It is low, but the exact pressure varies, generally the lower the pressure, the stronger the hurricane. Most have pressures less than 995 millibars. On rare occasions the pressure in the very strongest of hurricanes can drop below 900 millibars.

A tornado produces a greater pressure drop over a shorter distance than a hurricane.

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.

Hurricane hunters drop instruments called dropsondes into hurricanes to measure wind, temperature, and pressure. These dropsondes are released from the aircraft and collect data as they fall through the storm, transmitting it back to the aircraft for analysis.
It is low, but the exact pressure varies, generally the lower the pressure, the stronger the hurricane. Most have pressures less than 995 millibars. On rare occasions the pressure in the very strongest of hurricanes can drop below 900 millibars.
If a tornado passes near or over a barometer, it will measure a very rapid drop in pressure. How much the pressure drops depends on the strength of the tornado and how close the center of it comes tot he barometer.
The central pressure of the hurricane measures how strong the hurricane is. The lower the pressure is in the center of the hurricane, the higher the winds. If the pressure is very low, it is a very strong hurricane.

As a cold front approaches, the barometric pressure will typically decrease. This drop in pressure is due to the denser, cold air displacing the lighter, warm air. This change in pressure can be a signal of impending weather changes such as storms or precipitation.
