Because the Earth rotates.
The Coriolis force, a result of the earth's rotation, causes wind to follow a curved path over the earth's surface. As air moves across the rotating earth, its direction is deflected, causing winds to veer to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This causes the curved paths of winds commonly observed on the earth's surface.
Yes, gradient winds flow along curved paths due to the balance between the pressure gradient force and the Coriolis force. This results in the wind direction changing with height above the Earth's surface.

Everywhere is south from the north pole. Due to the rotation of the earth the majority of the winds follow the weather from west to east. The further south from the north pole, many other factors come into play that have a direct impact on the direction of the winds due to changes in the earth's profile, the flora, the variation of the surface temperatures, etc..
It is the Trajectory.
The geodesic solution is a mathematical concept used to find the shortest path between two points on a curved surface. It involves calculating the path that follows the curvature of the surface and minimizes the distance traveled between the two points.
Planetary winds do not blow directly north or south due to the Coriolis effect, which is caused by the Earth's rotation. As air moves from high to low pressure, the rotation of the Earth causes the winds to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection results in the winds generally flowing in a more east-west direction, creating prevailing wind patterns such as the trade winds and westerlies. Consequently, the winds follow a curved path rather than a straight north-south trajectory.
Prevailing winds do not blow in a perfectly straight line; they can be affected by various factors such as the Earth's rotation, landforms, and temperature gradients. As a result, prevailing winds often curve and change direction as they move across different regions.
Winds do flow down a pressure gradient from high pressure to low pressure, but the Coriolis effect deflects them, causing winds to move parallel to isobars. This creates geostrophic balance, where the pressure gradient force is balanced by the Coriolis force. As a result, winds don't blow directly from high to low pressure but rather follow a curved path.
Surface winds have to flow around such things as buildings and mountains. Upper-level winds have no 'obstructions' to alter their path.
A curved path followed by a projectile is called a trajectory. This is the path that an object takes when it is thrown or launched into the air.
Its the Coriolis effect. In fact, the wind is trying to blow straight and the earth is turning under it in a circular motion. The resulting path of the wind on the earth is a curved line.
