A bar is a unit used to measure pressure, similar to how a meter is a unit to measure distance. 1 bar is slightly lower than the average pressure at sea level.
A millibar is 1/1000 of bar, similar to how a millimeter is 1/1000 of a meter.
Gasses will move from an area of high pressure to low pressure, which causes wind. When the center of a hurricane suddenly drops in pressure by a lot, it is able to draw in more air, faster, causing a bigger hurricane.
