hurricanes and blizzards
in equitorial low pressure belt , low pressure is due to 1) intense heating 2) rate of rotation of earth is max. at equator . this results in max centrifugal force at equator which pushes the air away from the surface and causes low pressure condition.
Well this is a twofold answer because pressure itself does not mean anything when it comes to wind but rather pressure gradient or how fast the pressure drops over a given area. The faster the pressure drops over a small area the stronger the wind is forced to blow.Now lets take 2 examples here: atmospheric pressure 915 mb pressure drop: 25 mb Distance: 100 miles pressure drop/mile = 1/4 mb atmospheric pressure: 990 mb pressure drop: 25 mb Distance: 100 miles pressure drop/mile = 1/4 mb in these 2 situations the wind would blow the same speed. However like most situations the standard air pressure outside of the system would be around the same pressure or around 1010 mb so if we have the same 2 storms again but one of the storms is much larger then the other storm here is the result: atmospheric pressure 915 mb pressure drop: 95 mb Distance: 380 miles pressure drop/mile = 1/4 mb atmospheric pressure: 990 mb pressure drop: 20 mb Distance: 80 miles pressure drop/mile = 1/4 mb Again the wind speed would be the same since we are still falling at 1/4 mb per mile. So atmospheric pressure, storm size, surrounding air pressure, and other factors all come into play here... however if you had 2 of the same sized storms in the same atmospheric conditions but one had a pressure of 915 mb and the other had an air pressure of 990 mb the one with the 915 would have a higher wind speed due to a higher pressure gradient.
1. Florida, with 113 hurricanes, 37 of them major storms and two that reached Category 5 status (the strongest and most destructive of hurricanes).2. Texas, with 60 total hurricanes, 19 of them major. The majority (23) were Category 1 storms, and none were Category 5.3. Louisiana, with 52 total hurricanes, 20 of them major. One of those storms was a Category 5, and four were Category 4 storms.4. North Carolina, with 50 total hurricanes, 12 of them major storms. No Category 5 hurricanes have made landfall in North Carolina, but there has been one Category 4 storm.5. South Carolina with 30 hurricanes, six of them major. Two Category 4 hurricanes have made landfall on the South Carolina coast.The remaining top-ranked states for hurricane strikes are, in descending order, Alabama with 26, Georgia with 23, Mississippi with 16, New York with 12, Connecticut and Massachusetts with 11, Virginia with 10 and Rhode Island with nine.
Since the triple point of water is at 0.01 °C you could certainly boil water if you released the pressure and allowed it to drop low enough. In this case "low enough" would be down around 10 mbar (0.01 bar).
Twisters or Tornadoes.
The Four major air pressure zonessubtropical HighsSubpolar LowsPolar HighsEquatorial Low
Very simply put, cold air is denser than warm air - thus as air of differing temperature passes over you (or rather your barometer) the barometric pressure will change. The arrival of warm air will cause the barometric pressure to fall and as warm air holds more moisture than cold air a falling barometric pressure will herald the arrival of rain. Conversely, if the pressure rises this will indicate some nice sunny days to come Further, if the pressure falls (or rises) fast, then there are likely to be strong winds.

(2) high pressure toward regions of low pressure
Hurricanes are low pressure systems out over the open warm ocean waters and they get their energy from those warm waters. The low pressure system gathers clouds and storms and once these storms get organized enough they can eventually turn into hurricanes. They are hundreds of miles wide and can reach wind speeds of up to 155mph. Tornadoes are violently rotating columns of wind they form from a storm known as a supercell which is the most violent form of thunderstorm the atmosphere makes. They form when you have the right atmospheric conditions such as cold air colliding with warm moist unstable air. When those 2 air masses collide they form storms and these storms can then turn into supercells and the supercells can then produce a tornado if the supercell has a strong updraft and downdraft as well as strong enough rotation within the storm it can and does produce a tornado.
high and low
2 reasons for the system to cut out, low pressure, and high pressure. I am thinking you are experiencing low pressure and need to recharge your system.
Faulty sensor, low oil level, thin oil, plugged filter, worn bearings, worn pump,...........ANS 2 - A faulty sensor can not cause low oil pressure.
Gases show least ideal behaviour at 1- high pressure and 2- low temperature.
All low 2's.
where is the AC low pressure valve locted? check on passengers side, between firewall and engine, about 1 to 2 ft down!! the cap has a (L) on it!!
Blood pressure at or above 140/90 is considered high blood pressure. Conversely, pressures below 100/60 (or in some cases, 90/60) are considered low blood pressure.
