First, we'll consider the situation with no coriolis force, such as might occur near the equator. (I know, there wouldn't be snow and ice at sea level near the equator, but bear with me.) What sort of wind speed and direction would cause the net forces on the air to equal zero?
We know that the pressure gradient force will be directed from high pressure to low pressure, or from land to sea in this case. Therefore, for a steady state to be reached, the other force, friction, must be directed from sea to land. And since friction always causes a force opposite to the direction the wind is blowing, the steady-state wind must be from land to sea.
Next, we'll add the coriolis force, and take out friction. This would correspond to a midlatitude situation over a very smooth surface, or something aloft where friction is minimal.
The question is the same: If the accelerations are small or weak, there must be little or no net force on the air. So what sort of wind would we need for the net forces on the air to equal zero?
We know, again, that the pressure gradient force will be directed from high pressure to low pressure, or from land to sea. And again, for a steady state, the coriolis force must be directed from sea to land. What wind will imply a coriolis force directed from sea to land? It might help to take out some scratch paper and draw a few vectors to figure this one out.
