| 441796 | 2006-03-29 12:39:00 | Hey. can any one tell me (or tell me where to find - yes i've spent ages on google) the sea level pressure in NZ and the altitude of hamilton city? Thanks |

| 441797 | 2006-03-29 12:46:00 | The sea level pressure will vary with the weather, look at the most current weather map. | Rob99 (151) | ||
| 441798 | 2006-03-29 14:51:00 | Are you setting up a barometer, Fergie? The city library here has a Questions Desk, which is the fount of all wisdom. Try phoning yours for the height - after first checking whether it's on your city's website info. |

| 441800 | 2006-03-29 17:47:00 | Hey . can any one tell me (or tell me where to find - yes i've spent ages on google) the sea level pressure in NZ and the altitude of hamilton city? Thanks Universally, the sea level pressure anywhere in the world is 14 . 7 lb/square inch . Commonly spoken as the value ATU 1 . Unless your ocean/sea is lower than the rest of the seas/oceans of the world (highly unlikely), your values should be the same depending upon barometric conditions at the moment . High and Low pressure weather fronts will modify these values slightly and are detectable and used as weather forecasting devices . A kindly old gent from Italy, Mr . Bernoulli found these values to be useful in just such prognostication, but that hasn't made "weather-guessers" and alchemists any more accurate even to this day . You can use GoogleEarth to check the altitude of most anywhere in the world . . . locate the area of which you are interested and hover the pointer directly at that spot; there is an altitude readout on the lower left portion of the screen . |

| 441801 | 2006-03-29 20:48:00 | Atmosphereic pressure at sea level is generallly accepted as 101.3kpa, or "one atmosphere" of pressure. | somebody (208) | ||
| 441802 | 2006-03-29 20:52:00 | You could type in Hamilton NZ and get..... weather.gladstonefamily.net |

| 441803 | 2006-03-29 21:24:00 | I've just finished some research on this......... Mean MSL pressure varies from 1012 hPa in Invercargill to 1015 hPa in Kaitaia, while its standard deviation varies from 10 to 7.5 hPa. So, pressures are higher in the north, but less variable. Pressure at a particular location is normally distributed and has fractal properties. It has persistence, meaning that the pressure today is a good indicator of what the pressure will be tomorrow. hPa is hecto Pascal (hecto = 100) which is the same as a millibar. Pascal is Newtons/m^2. Probably more than you wanted to know.............. |

| 441804 | 2006-03-29 21:37:00 | The lowest sea level air pressure ever recorded was 870 mb (25.69 in.) in the eye of Typhoon (Tip) over the Pacific Ocean, whereas the highest sea level air pressure ever recorded was 1084 mb (32.01 in.) at Siberia associated with an extremely cold air mass.If you are trying to calculate your altitude with pressure using sea level as a reference point, you need to know the exact pressure. If you move a fair distance with your altimeter you need to re-calibrate. | Rob99 (151) | ||
| 441805 | 2006-03-29 23:19:00 | The social club of a highrise office block ran a competition to find out the height of the building using only a barometer. The production managers dropped the barometer from the top and timed the descent. The engineers took the pressure at the bottom and top. The office cleaner went to the janitor and said, 'You've got a plan of this building. If you tell me the height I'll give you a barometer." Which was the most accurate | Dally (6292) | ||
