A category one hurricane has a minimum central pressure of around 980 millibars.
No, Hurricane Irene in 2011 was not the most intense hurricane in world records. It was a Category 3 storm at its peak intensity. The most intense hurricane on record is Hurricane Patricia in 2015, which reached a maximum sustained wind speed of 215 mph.
The components of weather are:Temperature (degrees celsius)sunshine (how bright it is)cloud cover (oktas)precipitation (how much rain/hail/sleet/snow... there is)wind speed (wind strenght)wind direction (place the wind is coming from)atmospheric pressure (low or high pressure) measured in millibars (mb)
Lower pressure generally means higher wind speed. The relationship is approximately 1050-mm=Kt where mm is the pressure in millibars of mercury and Kt is the wind speed in knots. 1 knot = 1.15 mph. At extremely low pressures, the relationship can become a bit skewed due to eyewall replacement cycles but the formula is a good rule of thumb. Examples: Katrina (2005) Min pressure 902mm, max wind 150kt. Hugo (1989) min pressure 918mm, max wind 140kt.
A series of barometers can be used to predict wind speed and direction. Wind will move from higher pressure areas to lower pressure areas. The higher the pressure differential the higher the wind speed will be.
Barometer measures atmospheric pressure Anemometer measures wind speed
No, a wind vane is a tool that measures the direction of the wind, not atmospheric pressure. Millibars are a unit of pressure typically measured using a barometer.

A radiosonde measures atmospheric variables such as temperature, humidity, pressure, and wind during weather balloon ascents. These variables are typically recorded in units of degrees Celsius for temperature, percent for humidity, millibars for pressure, and meters per second for wind speed.
An anemometer is used for measuring the speed of wind,

A wind vane measures wind direction, not wind speed. It is a device that points in the direction from which the wind is blowing. Wind speed is typically measured using an anemometer.
wind speed = squrt(u^2+v^2).
942 is the median of those numbers.
