The wind at a standard height of 10 m 33 ft above ground. Differs from the geostrophic wind and the gradient wind because of friction with the Earth's surface.
Surface winds have to flow around such things as buildings and mountains. Upper-level winds have no 'obstructions' to alter their path.
If divergence exceeds convergence at the surface, it typically leads to a reduction in surface pressure, which can result in stronger surface winds. This is because the pressure gradient force, generated by the difference in pressure, drives air from high to low pressure. As air diverges from the surface and rises, it can enhance the wind speeds. Therefore, in this scenario, surface winds would generally get stronger.
If you mean Katrina peak winds were 175 mph. If you mean Katia peak winds were 135 mph.
The global winds that blow constantly from the same direction and cover a large part of the earth's surface are called the Trade Winds.
surface winds at your local base
A primary cause for surface winds on the earth is the Earths Rotation.
The amplitude is increased by strong surface winds.

Surface winds are slowed by friction caused by topography as well as the built environment.
high winds are normally caused by the unequal heating of the earths surface.
Surface winds have to flow around such things as buildings and mountains. Upper-level winds have no 'obstructions' to alter their path.
You mean trade winds. And they are winds that normally blow in the same direction on a regular basis.

The trade winds (also called trades) are the prevailing pattern of easterly surface winds found in the tropics near the Earth's equator[

Surface winds and upper air winds differ in their speed, direction, and altitude. Surface winds are influenced by friction with the Earth's surface and tend to be slower and more variable in direction. Upper air winds, on the other hand, are faster, more consistent in direction, and are influenced by factors such as temperature gradients and pressure systems. These differences in wind patterns impact weather by affecting the movement of air masses, the formation of weather systems, and the distribution of heat and moisture in the atmosphere.
