Given that there was complete synoptic volte-face at the end of
July, the mean sea-level synoptic field for the summer quarter showed a much weaker version of the June/July pattern; the cyclonic/northwesterly August was naturally not sufficient to offset the anticyclonic/southeasterly June and July. The Icelandic Low at 1009mbar in Denmark Strait was slightly deeper than normal while the Azores high 1025mbar just southwest of the Azores was normal in location and intensity although the characteristic summertime ridge to France and central Europe was stronger than normal. The main anomaly centres were +3mbar over the northern Baltic, -1.5mbar in Denmark Strait, and -1.5mbar near Madeira. Over the British Isles pressure was 0.0-1.0mbar above normal, with a weak E to SEly anomalous flow. CET (Manley): 17.5°C (+1.9 degC wrt 1971-2000) CET (Hadley): 17.3°C (+1.7 degC ditto ditto) EW rainfall: 152.5mm ( 88 per cent) EW sunshine: 715.7mm (119 per cent) Rainfall totals ranged from 333mm at Capel Curig (Snowdonia) to 59mm at Thorney Island (Hants); percentages varied between 151 at Herne Bay (Kent) and 29 at Shobdon (Herefs). Sunshine totals ranged from 921h at Shanklin (IoW) to 329h at Stornoway (W.Isles); percentages varied between 135 at Ross-on-Wye (Herefs) and 72 at Stornoway. (c) Philip Eden |
