Is the wind direction at high altitude the same as that on the ground?

1, the atmospheric motion at high altitude is mainly influenced by two forces, namely the horizontal pressure gradient force and the geostrophic deflection force (the friction force is too small to be ignored). From the point of view of balance, two forces can only be balanced if they are equal in magnitude and opposite in direction, so the wind direction is parallel to the isobar.

2. Considering the friction near the ground, it becomes influenced by three forces, so the forces tilt to the isobar after reaching balance, that is, there is an included angle.

3. Isobar map of the northern hemisphere. This problem needs to look at the high pressure center and low pressure center, as well as land and sea, as well as seasons and other comprehensive factors.

Extended data:

The direction of the current generated when the wire cuts the magnetic induction wire can be remembered by the direction of the palm and fingers of the right hand, that is, the right hand is extended so that the thumb is perpendicular to the other four fingers and all are in the same plane as the palm; Let the magnetic induction line enter from the palm of your hand, with your thumb pointing in the direction of the line movement. At this time, the direction pointed by the four fingers is the direction of the induced current. This is the right-hand rule to determine the direction of induced current when the conductor cuts the magnetic induction line.
