Explain why winds aloft flow roughly parallel to the isobars, while surface winds travel at an angle across the isobars.

Answer to Question 1

In both cases, pressure gradient force directs the wind directly perpendicular to the isobars, into the low pressure. In the upper atmosphere, there is almost no friction, which allows for greater wind speed. This in turn allows for a greater Coriolis deflection. The balance of these two forces results in winds that are parallel to the isobars. At the surface, increased friction slows the winds and also reduces the Coriolis deflection. The pressure gradient force does not change, however, so the balance of the three forces in play at the surface is slightly more in favor of the pressure gradient. The winds therefore still blow in towards the low, at an angle across the isobars, rather than flowing parallel to them as they do in the upper atmosphere.
