I seem to recall from my school days that an area of low pressure would be filled by higher pressure being drawn into it. I wonder with some curiosity how areas of low pressure develop in the first place, but more puzzled by the statement on a forecast I heard this evening that the current low causing the storm (Brendan) has deepened by 24mBar in the last 24 hours. How does a low get lower? Where does the air get sucked to, to make the pressure drop, because all the surrounding air should be at a higher pressure and should lessen the low.
