The Answer is second option (Tombouctou).
Because it's easier to scale hustle then relative humidity. and high relative humidity and high precipitation rate are the associates. I should know because I grew up in both greater New Orleans, which is subtropical, and the Oklahoma panhandle, which is semi-arid 5% relative humidity or higher is normal in New Orleans. While 6% relative humidity is relatively familiar in the Oklahoma and Texas panhandles.
Erosional landforms occur more often in the colder periods of the year because in this parts of the year there's usually more rain, and also there's snow ,and most importantly ice. The rain and snow contribute to the chemical decomposition of the rocks, while the ice with it's pressure contributes to the physical decomposition of the rocks, by literary increasing it's volume inside the cracks of the rocks and break them from the inside.

Explanation:
Effects of Wind
on forecasted temperatures
At night, the earth's surface cools by radiating heat off to space. The strongest cooling takes place right near the surface while temperatures at roughly 3000 feet are actually warmer than those at the surface. On a windy night, some of the warmer air aloft is mixed down towards the surface. This occurs because the winds are faster aloft than at the surface.
To visualize this, place one hand over the other about six inches apart. The bottom hand represents the air near the surface and the top hand represents the warmer wind higher up. Move the bottom hand slowly and the upper hand faster (to indicate the faster winds aloft). The faster air above and slower air below causes the air to overturn or spin (as in the picture below). This overturning motion is how warmer air from above is transported downward on windy nights.
