All of the following could enhance a single-celled thunderstorm EXCEPT
A) hot surface and an updraft dominated cloud.
B) cool surface and a downdraft dominated cloud.
C) extensive areas of cloud mergers between adjacent clouds.
D) vertical wind shear keeping precipitation separated from the uplift zone.

Question

Quizplus · Accepted Answer

A cool surface and a downdraft dominated cloud is the only option that could potentially hinder the growth of a single-celled thunderstorm. The other options all provide conditions that could enhance the storm. Hot surface and an updraft dominated cloud provide the necessary heat and instability for the storm to form and grow. Extensive areas of cloud mergers between adjacent clouds can lead to convergence and further uplift, also assisting in storm growth. Vertical wind shear can keep the precipitation separated from the uplifting air, allowing the storm to persist for longer periods.
