On the 0600 UKMO fax synoptic chart is a low 1033mb in the north sea. How
high can low pressures go? As high as you like. It's a low because the pressure there is lower than that of the air surrounding that location. If the surrounding pressure is 1055 mb you could have a 1054 mb low. At the other end of the scale (with 'low' highs) I have seen a high in the south Atlantic, central pressure 990 mb. -- Freddie Bayston Hill Shropshire 102m AMSL http://www.hosiene.co.uk/weather/cumulus/ https://twitter.com/#!/BaystonHillWx for hourly reports |

Joe Egginton Wolverhampton On the MetO FAX chart for 12Z Thursday there was a Low 1036 at 54N, 35E (Russia). There was just about a closed circulation and a bit of snow. The lowest High I have seen was a rather transient (12 -18 hours) High 978 over western Scotland in early December 1976. It was surrounded by several weak low centres in a large complex area of low pressure. Tudor Hughes, Warlingham, Surrey. |
