The first movement of air (wind) is always from high to low pressure. This is known as the Pressure Gradient Force (PGF). However, because the Earth is rotating, the Coriolis effect causes the wind to be deflected through 90 degrees. The resulting wind is known as the Geostrophic wind, and it blows parallel to isobars.
If the windmill wouldn't swivel with the windflow, it would stop, then turn into the opposite direction :-) But fortunately wind usually not changes its direction of flow 180 degrees suddenly, so the windmill can swivel ... and continue running. Wind energy generators, which usually run autonomously, also adjust the pitch of the blades according to wind speed. Above a certain top wind speed, usually 25 m/s , they shut down, regardless of direction of flow.
Wind is a cousin to the pressure. Pressure moves the wind.
The wind direction is measured with wind vanes or wind socks. Sexagesimal degrees.
The wind direction could be in any direction in a blizzard; it would be dependent on the location and which way the fronts are moving. Most of the blizzards in our area have little wind, usually thick, relentless snow fall.
The direction of the wind is measured using a wind vane. The wind direction is a good indicator of how the weather will change and what weather can be expected with that wind direction.

It pivots and aligns itself with the air flow, much like a flag.

The wind speed would be measured by an anemometer, while the wind direction would be shown by a wind vane. The wind vane is usually attached to the anemometer with most products.

Direct Current, sometimes abbreviated DC. When the current periodically changes direction, that's Alternating Current (AC)
All rivers flow down slope and usually towards the Sea.
