wind shear may decrease in a warmer world and that could mean fewer tornadoes.
On the other hand, wind shear is expected to decrease as the poles get warmer.
Both were dry, hilly landscapes with soil, sand, and wind shear as significant factors to deal with.
|wind shear |
A change in wind direction and speed between slightly different altitudes, especially a sudden downdraft. Depending on its scale, wind shear can cause a variety of effects, from minor turbulence to tornadoes. Wind shear caused by interactions between oceanic and atmospheric winds can be so strong that it can dissipate hurricanes. See also shear force.
