The following is a List of atmospheric pressure records in Europe and the extratropical Northern Atlantic (it does not include localised events, such as those that occur in tornados). Extreme pressure values in Europe show both seasonal and geographical differentiation. The greatest pressure extremes occur in winter (January) with the deepest lows occurring to the northwest of the continent with a diminishing influence of low pressure to the southeast towards Central Europe and Southeast Europe. This is related to the main cyclonic centre of the Icelandic Low, and the North Atlantic extratropical storm track, close to which have been observed some of the lowest atmospheric pressures of the Northern Hemisphere outside the tropics. Extreme high values are favoured over the north east of Euro
