What causes wind aviation?

SKYbrary Wiki In global terms, the main cause of wind is the difference in air pressure between two regions within the atmosphere. Initially, wind flows from high to low pressure, but as the wind speed increases, the rotation of the earth takes effect, causing the wind to travel along the direction of the isobars.

Is it better to fly in high or low pressure?

Lows: Low pressure areas are more important to flying weather than high pressure areas because the lows make the inclemencies that challenge us. The circulation around a low is counter-clockwise in the northern hemisphere and air flows around and into a low and then circulates upward.
