Question

What is the correlation between precipitation rate and the level of atmospheric pressure?

Answer 1

When there is as low pressure system the atmosphere drops and air rises. When the air rises it basically sucks up all the heat and moisture with it. You typically see more severe weather with lower pressure systems. With the high pressure the sinks although there is a possibility for rain.  The altitude has a major effect on pressure; if you live in Colorado the average pressure is lower in inches of mercury than kansas. I will include a pressure converter you can play around with.

Answer 2

As atmospheric pressure decreases, precipitation intensity increases. Hurricanes are by far the best example.

Answer 3

If a low pressure area intensifies,convergence of winds takes place on a large scale leading to strong convection currents.Due to these ascending air,condensation takes place resulting in the formation of convective clouds and more rain.Hence,low pressure increases  the precipitation rate in most of the cases.
