It varies. Irene was a high end category 2 with a pressure of around 942, but often that pressure would give you a a little bit stronger of a hurricane (maybe 120-130mph).
A Category 1 Hurricane has 980 Millibars or greater, however, to be a C1 Hurricane, its Wind Speed has to be 75-95 MPH.
No. Not even close. There are two main measures of hurricane intensity: wind speed and barometric pressure. Hurricane Irene is already past its peak of 120 mph winds and a pressure of 942 millibars (the lower the pressure, the stronger the storm). The strongest Hurricane on record in terms of wind speed was Hurricane Camille at 190 mph. The most intense tropical cyclone (generic term for hurricane, typhoon etc.) on recordwas Typhoon Tip with a pressure of 870 millibars.
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.

A wind vane measures direction of the wind. Millibars are a measure of pressure. A barometer measures in millibars.

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,

No. A wind vane is an instrument that can tell wind speed but not wind direction.
The current wind speed on the wind speed chart is 40 kilometers per hour.
wind speed = squrt(u^2+v^2).
