Landspouts are tornadoes that do not form from mesocyclones. They are similar in appearance and structure to fair-weather waterspouts, except that they form over land instead of water. They are thought to form similarly to weaker waterspouts [12] in that they form during the growth stage of convective clouds by the ingestion and tightening of ...

However, they form under clear skies and are no stronger than the weakest tornadoes. They form when a strong convective updraft is formed near the ground on a hot day. If there is enough low-level wind shear, the column of hot, rising air can develop a small cyclonic motion that can be seen near the ground.
"They are typically narrow, rope-like condensation funnels that form while the thunderstorm cloud is still growing and there is no rotating updraft", according to the National Weather Service. [2] Landspouts are considered tornadoes since a rapidly rotating column of air is in contact with both the surface and a cumuliform cloud .
The conditions that help them form are the same, but tornadoes come in all shapes and sizes. They can be narrow, rope-like swirls or large, wide funnels. How are tornadoes ranked?
