High Pressure?

Question

Does a persistent high pressure ever cause rain?

Answer 1

During the summer there will often be enough convective heating to trigger afternoon thunderstorms even under a persistent high pressure region such as the Bermuda High which covers much of the eastern US during the Summer and sometimes for an extended period of time. With this particular scenario there is a moist flow of unstable air from the Gulf of Mexico into the interior of the country, which sets up the right conditions for these thunderstorms.

Answer 2

You cannot get rain near the centre of a high pressure system as the air is descending and cloud will not form. Away from the centre the air becomes less stable and you can get convection producing large cumulus or cumulonimbus cloud. Convective clouds need instability through a great depth of the troposphere and you won't get that near the centre of highs.

Answer 3

never, high pressure areas are always good weather. only low pressure can allow rain and bad weather
