drop in air pressure..?

Question

a scuba diver is below the surface of the water when a storm approaches, dropping the air pressure above the water. would a sufficiently sensitive pressure gauge attached to his wrist register this drop in air pressure? Give your reasoning assuming that the diver's wrist does not move as the storm approaches.

I was going to say no because if the scuba diver is that far down in the ocean, he would not feel the drop in air pressure due to all the water pressure on top of him...is this wrong?

Answer 1

well, maybe.

If the air pressure was tremendously huge that it could extract waters oxygen molecules, then there would be less water, and the effect would be easier to feel

Answer 2

Storm surge. Like sucking on straw a low pressure area will elevate sea level vs. the geoid. Will the diver stay at constant altitude vs. the bottom or will he rise as the water above him rises?

The lowest hurricane pressure appears to be 892 (12.9 psi) or 924 (13.4 psi) mbar. One psi/2 feet of depth, more or less. The very worst hurricane would then show a depth change of ~3.6 feet if the diver stayed at constant altitude above the bottom.

In a nutshell: The tropics are warm. warm air rises. That lowers the rigidity. The poles are chilly. chilly air sinks. That will improve the rigidity. If it wasn't for the earth's rotation and the Coriolis rigidity, what rises between the tropics might in all probability circulate to the poles earlier sinking. however the remarkable-hand component divertion on the Coriolis rigidity in the northern hemisphere, spins the air that rose, at greater or less latitudes 30 north and 30 south into 2 belts of severe pressures. that's the place you will locate maximum deserts in the international. between that and the polar air, the hotter one rises over the less warm one and that types polar fronts at approximately latitudes 60 N and 60 S. with the aid of fact the air rises, it additionally lowers the rigidity. at the same time, those style what's suggested as the Hadley cells (tropics) the Ferrel cells (mid-latitudes) and Polar cells. and those are the main important air circulations in the international. The rigidity additionally variety during the direction of an afternoon. during sunlight hours, the sunlight heats the earth that heats a layer of air above it, that rises. This lowers the rigidity. At night, the chilly air from above sinks slowly and that will improve the rigidity. The exciting factor then is, why is it less warm with altitude when you consider that heat air rises? nicely, the increasing (suggested as, a convection) of the air during sunlight hours, happens lots, lots quicker than the slow sinking of the chilly air from above (suggested as, a subsidence) during the night. final yet no longer least: as heat air rises right into a lesser rigidity aloft, it cools down with the aid of adiabatic consequence and whilst the chilly air from above sinks, it warms up with the aid of the different adiabatic consequence. for this reason a low rigidity with the aid of increasing air, is linked with clouds and rain as moisture condenses whilst it cools down. yet in a severe rigidity, the air sinks, warms up and clouds evaporate, giving place to a clean sky.

Answer 4

The air pressure is such a small change u would not see it.
