A UVV MAX is a region of
lifting air in the atmosphere. This lifting is on the large scale. Some example
lifting processes are
low level warm air advection,
divergence aloft, frontal lifting,
and convergence in the lower troposphere. The region with the greatest amount of lifting will be at the
bulls eye of the UVV MAX. High UVV makes cloud formation and precipitation formation very likely. Rising air cools
and condenses out
moisture once it rises enough to reach saturation.
Generally, a UVV of 6 or greater will lead to clouds and precipitation (if air is not initially too dry). For drier air,
higher values of UVV will be needed to generate clouds and precipitation.
