What causes Winddays?
The Short Answer: Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.
How do clouds move against the wind?
When clouds are moving against the direction of the wind, it is often because of a phenomenon called wind shear, in which wind direction is different in the lower parts vs. upper parts of the atmosphere. This creates an unstable atmosphere, leading to rain and storms.
