How come we can't *see* either the high/low pressure systems--as they pass us overhead?

Question

Every time I see an 'H' or an 'L' on the map--and it's directly over where I live--how come I can't see THEM, but I can see the clouds and the blue skies?

Answer 1

because we can't see air

Answer 2

air is invisible. you cant see wind either but you can see the effects of wind- moving trees, clouds, feel a change in temperature...ect. think about that next time you see moving water, it is going to the lower density of pressure even though you cant see it, its a law of nature

Answer 3

Yes u do 'see' them, but u don't recognize them. A high/low pressure system is often related to the cloud,pressure, moisture, temperature and wind patterns that occur when a high/low p.s. is passing. For example, during the summer in the mid-latitudes, if it's really hot and cloudless, then it's a high pressure system overhead- an anticyclone. But when the  pressure significantly drops in a relatively short period of time, it's a low pressure system arriving - a cyclone (not same as the hurricane!! hurricanes are tropical cyclones)

Answer 4

What are you expecting to see, a big blue L in the sky?

Pressure is cause by variances in warm and cold air, do you have infrared vision? Then don't expect to see something like that.

Answer 5

Huh? you want to see a big blue "L" above you? You have too much imagination!
