Keith (Southend) wrote: Barometric pressure 1073.6mb ! -- Keith (Southend) http://www.southendweather.net I'm not sure how meaningful this is. The station-level pressure at 0000Z was 965 mb from the upper-air sounding. The station is at 2440 ft, 741 m. It's true that extrapolation to sea-level at about -43°C gives the stated pressure but presupposes a layer of cold air over 100 mb thick. In the hypothetical absence of the mountains that layer may well not be there. The mean station-level pressure at Ojmjakon in December is 925 mb so the pressure is certainly very high. The current QNH at Jakutsk (62N, 129E, 101 m) is 1051 mb. It's about 450 miles west of Ojmjakon, and the synoptic-scale gradients are very slight at the moment.
