I am searching for the history of the distribution of barometric pressure over each month of the year in Southern UK.

Barometric pressure appears to range from 950 to 1050 millibars for 97.5% of the time and account for 2 standard deviations from the norm. The norm is 1013 millibars which indicates that the shape of the curve is asymmetric and differs on each side of the norm and is more extended to the underside.

Is there a mathematical way or method to describe this distribution??

The area of greater interest is the area between the norm and 950 millibars as this area will determine the probability of dangerous flood events.
