Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. The force that generates wind is called as Pressure gradient force.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance.
